Frequently Asked Questions

X-Google-Original-From: Somebody ``` This means that the edited sender address was automatically replaced by a verified address before sending the message. Note that this is independent of receiving messages.
**(34) How are identities matched?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq34) Identities are as expected matched by account. For incoming messages the *to*, *cc*, *bcc*, *from* and *(X-)delivered/envelope/original-to* addresses will be checked (in this order) and for outgoing messages (drafts, outbox and sent) only the *from* addresses will be checked. Equal addresses have precedence over partially matching addresses, except for *delivered-to* addresses. The matched address will be shown as *via* in the addresses section of received messages (between the message header and message text). Note that identities needs to be enabled to be able to be matched and that identities of other accounts will not be considered. Matching will be done only once on receiving a message, so changing the configuration will not change existing messages. You could clear local messages by long pressing a folder in the folder list and synchronize the messages again though. It is possible to configure a [regex](https://en.wikipedia.org/wiki/Regular_expression) in the identity settings to match **the username** of an email address (the part before the @ sign). Note that the domain name (the parts after the @ sign) always needs to be equal to the domain name of the identity. Since version 1.1640 it is possible to match the full email address with a regex, which can be useful for matching alias domain names. If you like to match a catch-all email address, this regex is mostly okay: ``` .* ``` If you like to match the special purpose email addresses abc@example.com and xyx@example.com and like to have a fallback email address main@example.com as well, you could do something like this: * Identity: abc@example.com; regex: **(?i)abc** * Identity: xyz@example.com; regex: **(?i)xyz** * Identity: main@example.com; regex: **^(?i)((?!abc|xyz).)\*$** You can test a regex [here](https://regexr.com/). Matched identities can be used to color code messages. The identity color takes precedence over the folder and account color. Setting identity colors is a pro feature.
**(35) Why should I be careful with viewing images, attachments, the original message, and opening links?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq35) Viewing remotely stored images (see also [this FAQ](#user-content-faq27)) and opening links might not only tell the sender that you have seen the message, but will also leak your IP address. See also this question: [Why email's link is more dangerous than web search's link?](https://security.stackexchange.com/questions/241139/why-emails-link-is-more-dangerous-than-web-searchs-link). This BBC article is worth reading: [Spy pixels in emails have become endemic](https://www.bbc.com/news/technology-56071437). Opening attachments or viewing an original message might load remote content and execute scripts, that might not only cause privacy sensitive information to leak, but can also be a security risk. Note that your contacts could unknowingly send malicious messages if they got infected with malware. FairEmail formats messages again causing messages to look different from the original, but also uncovering phishing links. Note that reformatted messages are often better readable than original messages because the margins are removed, and font colors and sizes are standardized. The Gmail app shows images by default by downloading the images through a Google proxy server. Since the images are downloaded from the source server [in real-time](https://blog.filippo.io/how-the-new-gmail-image-proxy-works-and-what-this-means-for-you/), this is even less secure because Google is involved too without providing much benefit. You can show images and original messages by default for trusted senders on a case-by-case basis by checking *Do not ask this again for ...*.
**(36) How are settings files encrypted?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq36) Short version: AES 256 bit Long version: * The 256 bit key is generated with *PBKDF2WithHmacSHA1* using a 128 bit secure random salt and 65536 iterations * The cipher is *AES/CBC/PKCS5Padding*
**(37) How are passwords stored?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq37) All supported Android versions [encrypt all user data](https://source.android.com/security/encryption), so all data, including usernames, passwords, messages, etc, is stored encrypted. If the device is secured with a PIN, pattern or password, you can make the account and identity passwords visible. If this is a problem because you are sharing the device with other people, consider to use [user profiles](https://www.howtogeek.com/333484/how-to-set-up-multiple-user-profiles-on-android/).
**(39) How can I reduce the battery usage of FairEmail?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq39) Recent Android versions by default report *app usage* as a percentage in the Android battery settings screen. **Confusingly, *app usage* is not the same as *battery usage* and is not even directly related to battery usage!** The app usage (while in use) will be very high because FairEmail is using a foreground service which is considered as constant app usage by Android. However, this doesn't mean that FairEmail is constantly using battery power. The real battery usage can be seen by navigating to this screen: *Android settings*, *Battery*, three-dots menu *Battery usage*, three-dots menu *Show full device usage* Alternatively: tap on the *App settings* button in the main settings screen of the app and tap on *Battery*. As a rule of thumb the battery usage should be below or in any case not be much higher than *Mobile network standby* for one account with a stable network connection. If this isn't the case, please turn on *Auto optimize* in the receive settings. If this doesn't help, please [ask for support](https://contact.faircode.eu/?product=fairemailsupport). It is inevitable that synchronizing messages will use battery power because it requires network access and accessing the messages database. If you are comparing the battery usage of FairEmail with another email client, please make sure the other email client is setup similarly. For example comparing always sync (push messages) and (infrequent) periodic checking for new messages is not a fair comparison. Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage. Also, some email servers prematurely terminate idle connections, while [the standard](https://tools.ietf.org/html/rfc2177) says that an idle connection should be kept open for 29 minutes. In these cases you might want to synchronize periodically, for example each hour, instead of continuously. Note that polling frequently (more than every 30-60 minutes) will likely use more battery power than synchronizing always because connecting to the server and comparing the local and remote messages are expensive operations. [On some devices](https://dontkillmyapp.com/) it is necessary to *disable* battery optimizations (setup step 3) to keep connections to email servers open. In fact, leaving battery optimizations enabled can result in extra battery usage for all devices, even though this sounds contradictory! Most of the battery usage, not considering viewing messages, is due to synchronization (receiving and sending) of messages. So, to reduce the battery usage, set the number of days to synchronize message for to a lower value, especially if there are a lot of recent messages in a folder. Long press a folder name in the folders list and select *Edit properties* to access this setting. If you have at least once a day internet connectivity, it is sufficient to synchronize messages just for one day. Note that you can set the number of days to *keep* messages for to a higher number than to *synchronize* messages for. You could for example initially synchronize messages for a large number of days and after this has been completed reduce the number of days to synchronize messages, but leave the number of days to keep messages. After decreasing the number of days to keep messages, you might want to run the cleanup in the miscellaneous settings to remove old files. In the receive settings you can enable to always synchronize starred messages, which will allow you to keep older messages around while synchronizing messages for a limited number of days. Disabling the folder option *Automatically download message texts and attachments* will result in less network traffic and thus less battery usage. You could disable this option for example for the sent folder and the archive. Synchronizing messages at night is mostly not useful, so you can save on battery usage by not synchronizing at night. In the settings you can select a schedule for message synchronization (this is a pro feature). FairEmail will by default synchronize the folder list on each connection. Since folders are mostly not created, renamed and deleted very often, you can save some network and battery usage by disabling this in the receive settings. FairEmail will by default check if old messages were deleted from the server on each connection. If you don't mind that old messages that were delete from the server are still visible in FairEmail, you can save some network and battery usage by disabling this in the receive settings. Some providers don't follow the IMAP standard and [don't keep connections open](https://datatracker.ietf.org/doc/html/rfc3501#section-5.4) long enough, forcing FairEmail to reconnect often, causing extra battery usage. You can inspect the *Log* via the main navigation menu to check if there are frequent reconnects (connection closed/reset, read/write error/timeout, etc). You can workaround this by lowering the keep-alive interval in the advanced account settings to for example 9 or 15 minutes. Note that battery optimizations need to be disabled in setup step 3 to reliably keep connections alive. Some providers send every two minutes something like '*Still here*' resulting in network traffic and your device to wake up and causing unnecessary extra battery usage. You can inspect the *Log* via the main navigation menu to check if your provider is doing this. If your provider is using [Dovecot](https://www.dovecot.org/) as IMAP server, you could ask your provider to change the [imap_idle_notify_interval](https://wiki.dovecot.org/Timeouts) setting to a higher value or better yet, to disable this. If your provider is not able or willing to change/disable this, you should consider to switch to periodically instead of continuous synchronization. You can change this in the receive settings. If you got the message *This provider does not support push messages* while configuring an account, consider switching to a modern provider which supports push messages (IMAP IDLE) to reduce battery usage. If your device has an [AMOLED](https://en.wikipedia.org/wiki/AMOLED) screen, you can save battery usage while viewing messages by switching to the black theme. If auto optimize in the receive settings is enabled, an account will automatically be switched to periodically checking for new messages when the email server: * Says '*Still here*' within 3 minutes * The email server does not support push messages * The keep-alive interval is lower than 12 minutes In addition, the trash and spam folders will be automatically set to checking for new messages after three successive [too many simultaneous connections](#user-content-faq23) errors.
**(40) How can I reduce the data usage of FairEmail?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq40) You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions. It is inevitable that data will be used to synchronize messages. If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings). To reduce data usage, you could change these advanced receive settings: * Check if old messages were removed from the server: disable * Synchronize (shared) folder list: disable By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.
**(41) How can I fix the error 'Handshake failed'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq41) There are several possible causes, so please read to the end of this answer. The error '*Handshake failed ... WRONG_VERSION_NUMBER ...*' might mean that you are trying to connect to an IMAP or SMTP server without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP), or that a wrong protocol (SSL/TLS or STARTTLS) is being used. Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP). If your provider doesn't support encrypted connections, you should ask to make this possible. If this isn't an option, you could enable *Allow insecure connections* both in the advanced settings AND the account/identity settings. See also [this FAQ](#user-content-faq4). The error '*Handshake failed ... SSLV3_ALERT_ILLEGAL_PARAMETER ...*' is either caused by a bug in the SSL protocol implementation or by a too short DH key on the email server and can unfortunately not be fixed by FairEmail. The error '*Handshake failed ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...*' might be caused by the provider still using RC4, which isn't supported since [Android 7](https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl) anymore. The error '*Handshake failed SSL handshake terminated ... SSLV3_ALERT_HANDSHAKE_FAILURE ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO*' can be caused by [this Android 7.0 bug](https://issuetracker.google.com/issues/37122132). This can unfortunately not be fixed by FairEmail. The error '*Handshake failed ... UNSUPPORTED_PROTOCOL or TLSV1_ALERT_PROTOCOL_VERSION or SSLV3_ALERT_HANDSHAKE_FAILURE ...*' might be caused by enabling **hardening connections**, or requiring TLS 1.3 in the connection settings or by Android not supporting older protocols anymore, like SSLv3. Android 8 Oreo and later [do not support](https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all) SSLv3 anymore. There is no way to workaround lacking RC4 and SSLv3 support because it has completely been removed from Android (which should say something). Please [see here](https://developer.android.com/reference/javax/net/ssl/SSLSocket) for an overview of supported protocols and cipher suites by Android version. You can use [this website](https://ssl-tools.net/mailservers) or [this website](https://www.immuniweb.com/ssl/) to check for SSL/TLS problems of email servers.
**(42) Can you add a new provider to the list of providers?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq42) If the provider is used by more than a few people, yes, with pleasure. The following information is needed: ``` // this is not needed ``` The EFF [writes](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery): "*Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted.*" So, pure SSL connections are safer than using [STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) and therefore preferred. Please make sure receiving and sending messages works properly before contacting me to add a provider. See below about how to contact me.
**(43) Can you show the original ...?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq43) Show original, shows the original message as the sender has sent it, including original fonts, colors, margins, etc. FairEmail does and will not alter this in any way, except for requesting [TEXT_AUTOSIZING](https://developer.android.com/reference/android/webkit/WebSettings.LayoutAlgorithm), which will *attempt* to make small text more readable.
**~~(44) Can you show contact photos / identicons in the sent folder?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq44) ~~Contact photos and identicons are always shown for the sender because this is necessary for conversation threads.~~ ~~Getting contact photos for both the sender and receiver is not really an option because getting contact photo is an expensive operation.~~
**(45) How can I fix 'This key is not available. To use it, you must import it as one of your own!'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq45) You'll get the message *This key is not available. To use it, you must import it as one of your own!* when trying to decrypt a message with a public key. To fix this you'll need to import the private key.
**(46) Why does the message list keep refreshing?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq46) If you see a 'spinner' at the top of the message list, the folder is still being synchronized with the remote server. You can see the progress of the synchronization in the folder list. See the legend about what the icons and numbers mean. The speed of your device and internet connection and the number of days to synchronize messages determine how long synchronization will take. Note that you shouldn't set the number of days to synchronize messages to more than one day in most cases, see also [this FAQ](#user-content-faq39).
**(47) How do I solve the error 'No primary account or no drafts folder'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq47) You'll get the error message *No primary account or no drafts folder* when trying to compose a message while there is no account set to be the primary account or when there is no drafts folder selected for the primary account. This can happen for example when you start FairEmail to compose a message from another app. FairEmail needs to know where to store the draft, so you'll need to select one account to be the primary account and/or you'll need to select a drafts folder for the primary account. This can also happen when you try to reply to a message or to forward a message from an account with no drafts folder while there is no primary account or when the primary account does not have a drafts folder. Please see [this FAQ](#user-content-faq141) for some more information.
**~~(48) How do I solve the error 'No primary account or no archive folder'?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq48) ~~You'll get the error message *No primary account or no archive folder* when searching for messages from another app. FairEmail needs to know where to search, so you'll need to select one account to be the primary account and/or you'll need to select a archive folder for the primary account.~~
**(49) How do I fix 'An outdated app sent a file path instead of a file stream'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq49) You likely selected or sent an attachment or image with an outdated file manager or an outdated app which assumes all apps still have storage permissions. For security and privacy reasons modern apps like FairEmail have no full access to all files anymore. This can result into the error message *An outdated app sent a file path instead of a file stream* if a file name instead of a file stream is being shared with FairEmail because FairEmail cannot randomly open files. You can fix this by switching to an up-to-date file manager or an app designed for recent Android versions. Alternatively, you can grant FairEmail read access to the storage space on your device in the Android app settings. Note that this workaround [won't work on Android Q](https://developer.android.com/preview/privacy/scoped-storage) anymore. See also [question 25](#user-content-faq25) and [what Google writes about it](https://developer.android.com/training/secure-file-sharing/share-file#RespondToRequest).
**(50) Can you add an option to synchronize all messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq50) You can synchronize more or even all messages by long pressing a folder (inbox) in the folder list of an account (tap on the account name in the navigation menu) and selecting *Synchronize more* in the popup menu.
**(51) How are folders sorted?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq51) Folders are first sorted on account order (by default on account name) and within an account with special, system folders on top, followed by folders set to synchronize. Within each category the folders are sorted on (display) name. You can set the display name by long pressing a folder in the folder list and selecting *Edit properties*. The navigation (hamburger) menu item *Order folders* in the settings can be used to manually order the folders.
**(52) Why does it take some time to reconnect to an account?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq52) There is no reliable way to know if an account connection was terminated gracefully or forcefully. Trying to reconnect to an account while the account connection was terminated forcefully too often can result in problems like [too many simultaneous connections](#user-content-faq23) or even the account being blocked. To prevent such problems, FairEmail waits 90 seconds until trying to reconnect again. You can long press *Settings* in the navigation menu to reconnect immediately.
**(53) Can you stick the message action bar to the top/bottom?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq53) The message action bar works on a single message and the bottom action bar works on all the messages in the conversation. Since there is often more than one message in a conversation, this is not possible. Moreover, there are quite some message specific actions, like forwarding. Moving the message action bar to the bottom of the message is visually not appealing because there is already a conversation action bar at the bottom of the screen. Note that there are not many, if any, email apps that display a conversation as a list of expandable messages. This has a lot of advantages, but the also causes the need for message specific actions.
**~~(54) How do I use a namespace prefix?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq54) ~~A namespace prefix is used to automatically remove the prefix providers sometimes add to folder names.~~ ~~For example the Gmail spam folder is called:~~ ``` [Gmail]/Spam ``` ~~By setting the namespace prefix to *[Gmail]* FairEmail will automatically remove *[Gmail]/* from all folder names.~~
**(55) How can I mark all messages as read / move or delete all messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq55) You can use multiple select for this. Long press the first message, don't lift your finger and slide down to the last message. Then use the three dot action button to execute the desired action.
**(56) Can you add support for JMAP?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq56) There are almost no providers offering the [JMAP](https://jmap.io/) protocol, so it is not worth a lot of effort to add support for this to FairEmail.
**(57) Can I use HTML in signatures?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq57) Yes, you can use [HTML](https://en.wikipedia.org/wiki/HTML). In the signature editor you can switch to HTML mode via the three-dots menu. Note that if you switch back to the text editor that not all HTML might be rendered as-is because the Android text editor is not able to render all HTML. Similarly, if you use the text editor, the HTML might be altered in unexpected ways. If you want to use preformatted text, like [ASCII art](https://en.wikipedia.org/wiki/ASCII_art), you should wrap the text in a *pre* element, like this: ```

  |\_/|
 / @ @ \
( > º < )
 `>>x<<´
 /  O  \
 

``` If you want to resize an image, you could do it like this: ``` ``` The recipient of your message might not like large images in messages, so it is better to resize images with an image editor first.
**(58) What does an open/closed email icon mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq58) The email icon in the folder list can be open (outlined) or closed (solid):  Message bodies and attachments are not downloaded by default.  Message bodies and attachments are downloaded by default.
**(59) Can original messages be opened in the browser?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq59) For security reasons the files with the original message texts are not accessible to other apps, so this is not possible. In theory the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) could be used to share these files, but even Google's Chrome cannot handle this.
**(60) Did you know ...?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq60) * Did you know that starred messages can be synchronized/kept always?

**(61) Why are some messages shown dimmed?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq61) Messages shown dimmed (grayed) are locally moved messages for which the move is not confirmed by the server yet. This can happen when there is no connection to the server or the account (yet). These messages will be synchronized after a connection to the server and the account has been made or, if this never happens, will be deleted if they are too old to be synchronized. You might need to manually synchronize the folder, for example by pulling down. You can view these messages, but you cannot move these messages again until the previous move has been confirmed. Pending [operations](#user-content-faq3) are shown in the operations view accessible from the main navigation menu.
**(62) Which authentication methods are supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq62) The following authentication methods are supported and used in this order: * CRAM-MD5 * LOGIN * PLAIN * NTLM (untested) * XOAUTH2 ([Gmail](https://developers.google.com/gmail/imap/xoauth2-protocol), [Yandex](https://tech.yandex.com/oauth/)) SASL authentication methods, besides CRAM-MD5, are not supported because [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication. If your provider requires an unsupported authentication method, you'll likely get the error message *authentication failed*. [Client certificates](https://en.wikipedia.org/wiki/Client_certificate) can be selected in the account and identity settings. [Server Name Indication](https://en.wikipedia.org/wiki/Server_Name_Indication) is supported by [all supported Android versions](https://developer.android.com/training/articles/security-ssl).
**(63) How are images resized for displaying on screens?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq63) You can add images to a message in two ways: * As attachment, by tapping on the paperclip icon button in the bottom action bar * As image, by tapping on the image icon button in the bottom action bar If you disabled the bottom action bar, you can enable it again via the three-dots menu at the top right of the message editor. An attachment will always be sent as-is. An image can be added as attachment or inserted into a message and you can select to reduce the size of the image and to remove privacy sensitive information. Images will be scaled down using whole number factors to reduce memory usage and to retain the image quality. Scaled images will be saved with a compression ratio of 90 %. If the image options do not appear, you can enable them again via the three-dots menu. Note that most email providers limit the total message size to 10-50 MB. Automatically resizing of inline and/or attached images and the maximum target image size can be configured in the send settings.
**~~(64) Can you add custom actions for swipe left/right?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq64) ~~The most natural thing to do when swiping a list entry left or right is to remove the entry from the list.~~ ~~The most natural action in the context of an email app is moving the message out of the folder to another folder.~~ ~~You can select the folder to move to in the account settings.~~ ~~Other actions, like marking messages read and snoozing messages are available via multiple selection.~~ ~~You can long press a message to start multiple selection. See also [this question](#user-content-faq55).~~ ~~Swiping left or right to mark a message read or unread is unnatural because the message first goes away and later comes back in a different shape.~~ ~~Note that there is an advanced option to mark messages automatically read on moving,~~ ~~which is in most cases a perfect replacement for the sequence mark read and move to some folder.~~ ~~You can also mark messages read from new message notifications.~~ ~~If you want to read a message later, you can hide it until a specific time by using the *snooze* menu.~~
**(65) Why are some attachments shown dimmed?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq65) Inline (image) attachments are shown dimmed. [Inline attachments](https://tools.ietf.org/html/rfc2183) are supposed to be downloaded and shown automatically, but since FairEmail doesn't always download attachments automatically, see also [this FAQ](#user-content-faq40), FairEmail shows all attachment types. To distinguish inline and regular attachments, inline attachments are shown dimmed.
**(66) Is FairEmail available in the Google Play Family Library?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq66) "*You can't share in-app purchases and free apps with your family members.*" See [here](https://support.google.com/googleone/answer/7007852) under "*See if content is eligible to be added to Family Library*", "*Apps & games*". In other words, only subscriptions can be shared and since there is no subscription, FairEmail is not shareable via the Google Play Family Library.
**(67) How can I snooze conversations?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq67) Multiple select one of more conversations (long press to start multiple selecting), tap the three dot button and select *Snooze ...*. Alternatively, in the expanded message view use *Snooze ...* in the message three-dots 'more' menu or the time-lapse action in the bottom action bar. Select the time the conversation(s) should snooze and confirm by tapping OK. The conversations will be hidden for the selected time and shown again afterwards. You will receive a new message notification as reminder. It is also possible to snooze messages with [a rule](#user-content-faq71), which will also allow you to move messages to a folder to let them be auto snoozed. You can show snoozed messages by unchecking *Filter out* > *Hidden* in the three dot overflow menu. You can tap on the small snooze icon to see until when a conversation is snoozed. By selecting a zero snooze duration you can cancel snoozing. Third party apps do not have access to the Gmail snoozed messages folder.
**~~(68) Why can Adobe Acrobat reader not open PDF attachments / Microsoft apps not open attached documents?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq68) ~~Adobe Acrobat reader and Microsoft apps still expects full access to all stored files,~~ ~~while apps should use the [Storage Access Framework](https://developer.android.com/guide/topics/providers/document-provider) since Android KitKat (2013)~~ ~~to have access to actively shared files only. This is for privacy and security reasons.~~ ~~You can workaround this by saving the attachment and opening it from the Adobe Acrobat reader / Microsoft app,~~ ~~but you are advised to install an up-to-date and preferably open source PDF reader / document viewer,~~ ~~for example one listed [here](https://github.com/offa/android-foss#-document--pdf-viewer).~~
**(69) Can you add auto scroll up on new message?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq69) The message list is automatically scrolled up when navigating from a new message notification or after a manual refresh. Always automatically scrolling up on arrival of new messages would interfere with your own scrolling, but if you like you can enable this in the settings.
**(70) When will messages be auto expanded?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq70) When navigation to a conversation one message will be expanded if: * There is just one message in the conversation * There is exactly one unread message in the conversation * There is exactly one starred (favorite) message in the conversation (since version 1.1508) There is one exception: the message was not downloaded yet and the message is too large to download automatically on a metered (mobile) connection. You can set or disable the maximum message size on the 'connection' settings tab. Duplicate (archived) messages, trashed messages and draft messages are not counted. Messages will automatically be marked read on expanding, unless this was disabled in the individual account settings.
**(71) How do I use filter rules?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq71) You can edit filter rules by long pressing a folder in the folder list of an account (tap the account name in the navigation/side menu). New rules will be applied to new messages received in the folder, not to existing messages. You can check the rule and apply the rule to existing messages or, alternatively, long press the rule in the rule list and select *Execute now*. You'll need to give a rule a name and you'll need to define the order in which a rule should be executed relative to other rules. You can disable a rule and you can stop processing other rules after a rule has been executed, which can be used to create a *not* condition. The following rule conditions are available: * Sender contains or sender is contact * Recipient contains * Subject contains * Has attachments (optional of specific type) * Header contains * Text contains (since version 1.1785) * Absolute time (received) between (since version 1.1540) * Relative time (received) between All the conditions of a rule need to be true for the rule action to be executed. All conditions are optional, but there needs to be at least one condition, to prevent matching all messages. If you want to match all senders or all recipients, you can just use the @ character as condition because all email addresses will contain this character. If you want to match a domain name, you can use as a condition something like *@example.org* Note that email addresses are formatted like this: `` "Somebody" `` Note that message texts are normalized, which means that all whitespaces (spaces, tabs, line breaks, etc) are replaced by a single space. This makes it easier to match texts on multiple lines or when the line break is at different places. You can use multiple rules, possibly with a *stop processing*, for an *or* or a *not* condition. Matching is not case sensitive, unless you use [regular expressions](https://en.wikipedia.org/wiki/Regular_expression). Please see [here](https://developer.android.com/reference/java/util/regex/Pattern) for the documentation of Java regular expressions. Note that you need to match the complete text from the first to the last character. You can test a regex [here](https://regexr.com/). Note that a regular expression supports an *or* operator, so if you want to match multiple senders, you can do this: `` .*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.* `` Note that [dot all mode](https://developer.android.com/reference/java/util/regex/Pattern#DOTALL) is enabled to be able to match [unfolded headers](https://tools.ietf.org/html/rfc2822#section-3.2.3). You can select one of these actions to apply to matching messages: * No action (useful for *not*) * Mark as read * Mark as unread * Hide * Suppress notification * Snooze * Add star * Set importance (local priority) * Add keyword * Move * Copy (Gmail: label) * Delete permanently (since version 1.1801) * Play sound (since version 1.1803; experimental) * Answer/forward (with template) * Text-to-speech (sender and subject) * Automation (Tasker, etc) **Important**: permanent deletion is **irreversible**. Instead, consider to move messages to the trash folder and to set up auto deletion for the trash folder in the folder properties (long press the folder in the folder list of an account). If you want to forward a message, consider to use a *move* action instead. This will be more reliable than forwarding because forwarded messages might be considered as spam.
A *move* action can optionally create subfolders (since version 1.1966) to move messages to, for which you can use the following placeholders: ``` $week$ $month$ $year$ $domain$ ```
Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space it is by default not possible to preview which messages would match a header rule condition. You can enable downloading message headers in the connection settings and check headers conditions anyway (since version 1.1599). Some common header conditions (regex): * *.*Auto-Submitted:.** [RFC3834](https://tools.ietf.org/html/rfc3834) * *.*List-Unsubscribe:.** [RFC3834](https://datatracker.ietf.org/doc/html/rfc2369) * *.*Content-Type: multipart/report.** [RFC3462](https://tools.ietf.org/html/rfc3462) To match *set* IMAP flags (keywords) via a header condition (since version 1.1777): ``` $$ ``` To match *set* message flags via a header condition (since version 1.1777): ``` $$seen$ $$answered$ $$flagged$ $$deleted$ ``` To match *passed* message checks via a header condition (since version 1.1787): ``` $$tls$ (since version 1.1826) $$dkim$ $$spf$ $$dmarc$ $$mx$ $$blocklist$ $$replydomain$ $$nofrom$ (since version 1.1791) $$multifrom$ (since version 1.1791) $$automatic$ (since version 1.1862) $$lowpriority$ (since version 1.1958) $$highpriority$ (since version 1.1958) ``` Note that *regex* should be disable and that there should be no white space. Please be aware that a difference in the *from* and *reply-to* domain, and no or multi *from* addresses isn't a good indication of spam. Since the app sets the keyword *$Filtered$* after the rules have been executed for a message, you can create a rule to prevent the rules from being executed again (which is sometimes desirable): * Name: anything you like * Order: lower than all other rules, for example 0 * Stop processing rules after executing this rule: enabled * Header contains: *$$Filtered$* (no spaces) * Action: No action Note that not all email servers support IMAP keywords.
The automation action will broadcast the intent *eu.faircode.email.AUTOMATION* with the following string extras: * *name* * *sender* * *subject* * *received* (ISO 8601 date/time) An app like Tasker can listen for this intent and perform some action.
In the three-dots *more* message menu there is an item to create a rule for a received message with the most common conditions filled in.
If you want to set up archiving by week, month, year, etc, you can do this with filter rules with an absolute time condition on a 'jump' archive folder where archived messages are being moved to as a first step. The filter rules will move the messages to a (sub) archive folder as a second step. The POP3 protocol does not support setting keywords and moving or copying messages. Using rules is a pro feature.
**(72) What are primary accounts/identities?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq72) The primary account is used when the account is ambiguous, for example when starting a new draft from the unified inbox. Similarly, the primary identity of an account is used when the identity is ambiguous. The default email address is the email address of the primary identity of the primary account. There can be just one primary account and there can be just one primary identity per account. You can set an account or an identity to be primary by long pressing it in the list of accounts or identities. You can go to the list of accounts via *Manual setup and account options* in the main setup screen.
**(73) Is moving messages across accounts safe/efficient?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq73) Moving messages across accounts is safe because the raw, original messages will be downloaded and moved and because the source messages will be deleted only after the target messages have been added Batch moving messages across accounts is efficient if both the source folder and target folder are set to synchronize, else FairEmail needs to connect to the folder(s) for each message.
**(74) Why do I see duplicate messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq74) Some providers, notably Gmail, list all messages in all folders, except trashed messages, in the archive (all messages) folder too. FairEmail shows all these messages in a non obtrusive way to indicate that these messages are in fact the same message. Gmail allows one message to have multiple labels, which are presented to FairEmail as folders. This means that messages with multiple labels will be shown multiple times as well.
**(75) Can you make an iOS, Windows, Linux, etc version?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq75) A lot of knowledge and experience is required to successfully develop an app for a specific platform, which is why I develop apps for Android only.
**(76) What does 'Clear local messages' do?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq76) The folder menu *Clear local messages* removes messages from the device which are present on the server too. It does not delete messages from the server. This can be useful after changing the folder settings to not download the message content (text and attachments), for example to save space.
**(77) Why are messages sometimes shown with a small delay?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq77) Depending on the speed of your device (processor speed and maybe even more memory speed) messages might be displayed with a small delay. FairEmail is designed to dynamically handle a large number of messages without running out of memory. This means that messages needs to be read from a database and that this database needs to be watched for changes, both of which might cause small delays. Some convenience features, like grouping messages to display conversation threads and determining the previous/next message, take a little extra time. Note that there is no *the* next message because in the meantime a new message might have been arrived. When comparing the speed of FairEmail with similar apps this should be part of the comparison. It is easy to write a similar, faster app which just displays a lineair list of messages while possible using too much memory, but it is not so easy to properly manage resource usage and to offer more advanced features like conversation threading. FairEmail is based on the state-of-the-art [Android architecture components](https://developer.android.com/topic/libraries/architecture/), so there is little room for performance improvements.
**(78) How do I use schedules?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq78) In the receive settings you can enable scheduling and set a time period and the days of the week *when* messages should be *received*. Note that an end time equal to or earlier than the start time is considered to be 24 hours later. Since version 1.1880 is is possible to exclude accounts from scheduling in the advanced account settings. This means you can synchronize a business account during business hours only and make an exception for personal accounts. Automation, see below, can be used for more advanced schedules, like for example multiple synchronization periods per day or different synchronization periods for different days. It is possible to install FairEmail in multiple user profiles, for example a personal and a work profile, and to configure FairEmail differently in each profile, which is another possibility to have different synchronization schedules and to synchronize a different set of accounts. It is also possible to create [filter rules](#user-content-faq71) with a time condition and to snooze messages until the end time of the time condition. This way it is possible to *snooze* business related messages until the start of the business hours. This also means that the messages will be on your device for when there is (temporarily) no internet connection. How to: * Go to the folder list of an account by tapping on the account name in the navigation menu (left side menu) * Long press the inbox in the folder list and select *Edit rules* * Tap om the big *plus* button at the bottom to create a new rule * Enter as name for example *Snooze business messages* * Under relative time select a start and end date/time, for example Friday 17:00 and Monday 09:00 * Select *Snooze* as action * Save the rule with the save button in the bottom action bar Note that recent Android versions allow overriding DND (Do Not Disturb) per notification channel and per app, which could be used to (not) silence specific (business) notifications. Please [see here](https://support.google.com/android/answer/9069335) for more information. For more complex schemes you could set one or more accounts to manual synchronization and send this command to FairEmail to check for new messages: ``` (adb shell) am start-foreground-service -a eu.faircode.email.POLL ``` For a specific account: ``` (adb shell) am start-foreground-service -a eu.faircode.email.POLL --es account Gmail ``` You can also automate turning receiving messages on and off by sending these commands to FairEmail: ``` (adb shell) am start-foreground-service -a eu.faircode.email.ENABLE (adb shell) am start-foreground-service -a eu.faircode.email.DISABLE ``` To enable/disable a specific account: ``` (adb shell) am start-foreground-service -a eu.faircode.email.ENABLE --es account Gmail (adb shell) am start-foreground-service -a eu.faircode.email.DISABLE --es account Gmail ``` Note that disabling an account will hide the account and all associated folders and messages. Since version 1.1600 an account will be disabled/enabled by setting the account to manual/automatic sync, so the folders and messages keep being accessible. To set the poll interval: ``` (adb shell) adb shell am start-foreground-service -a eu.faircode.email.INTERVAL --ei minutes nnn ``` Where *nnn* is one of 0, 5, 15, 30, 60, 120, 240, 480, 1440. A value of 0 means push messages. You can automatically send commands with for example [Tasker](https://tasker.joaoapps.com/userguide/en/intents.html): ``` New task: Something recognizable Action Category: Misc/Send Intent Action: eu.faircode.email.ENABLE Target: Service ``` To enable/disable an account with the name *Gmail*: ``` Extras: account:Gmail ``` Account names are case sensitive. Scheduling is a pro feature.
**(79) How do I use synchronize on demand (manual)?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq79) Normally, FairEmail maintains a connection to the configured email servers whenever possible to receive messages in real-time. If you don't want this, for example to be not disturbed or to save on battery usage, just disable receiving in the receive settings. This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification. You can also enable *Synchronize manually* in the advanced account settings if you want to manually synchronize specific accounts only. You can use pull-down-to-refresh in a message list or use the folder menu *Synchronize now* to manually synchronize messages. If you want to synchronize some or all folders of an account manually, just disable synchronization for the folders (but not of the account). You'll likely want to disabled [browse on server](#user-content-faq24) too.
**~~(80) How do I fix the error 'Unable to load BODYSTRUCTURE'?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq80) ~~The error message *Unable to load BODYSTRUCTURE* is caused by bugs in the email server,~~ ~~see [here](https://javaee.github.io/javamail/FAQ#imapserverbug) for more details.~~ ~~FairEmail already tries to workaround these bugs, but if this fail you'll need to ask for support from your provider.~~
**(81) Can you make the background of the original message view dark in dark themes?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq81) The original message view will use a dark background when using a dark theme for Android version 10 and later. For Android before version 10 Google removed this feature from the [Android System WebView](https://play.google.com/store/apps/details?id=com.google.android.webview), even though it worked fine in most cases. Please see [this issue](https://issuetracker.google.com/issues/237785596) (requires a Google account login) requesting to restore this feature again for more information.
**(82) What is a tracking image?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq82) Please see [here](https://en.wikipedia.org/wiki/Web_beacon) about what a tracking image exactly is. In short tracking images keep track if you opened a message. The BBC article '[Spy pixels in emails have become endemic](https://www.bbc.com/news/technology-56071437)' is worth reading. FairEmail will in most cases automatically recognize tracking images and replace them by this icon:  Automatic recognition of tracking images can be disabled in the privacy settings.
**(84) What are local contacts for?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq84) Local contact information is based on names and addresses found in incoming and outgoing messages. The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail. Another use is to generate [shortcuts](#user-content-faq31) on recent Android versions to quickly send a message to frequently contacted people. This is also why the number of times contacted and the last time contacted is being recorded and why you can make a contact a favorite or exclude it from favorites by long pressing it. The list of contacts is sorted on number of times contacted and the last time contacted. By default only names and addresses to whom you send messages to will be recorded. You can change this in the send settings.
**(85) Why is an identity not available?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq85) An identity is available for sending a new message or replying or forwarding an existing message only if: * the identity is set to synchronize (send messages) * the associated account is set to synchronize (receive messages) * the associated account has a drafts folder FairEmail will try to select the best identity based on the *to* address of the message replied to / being forwarded.
**~~(86) What are 'extra privacy features'?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq86) ~~The advanced option *extra privacy features* enables:~~ * ~~Looking up the owner of the IP address of a link~~ * ~~Detection and removal of [tracking images](#user-content-faq82)~~
**(87) What does 'invalid credentials' mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq87) The error message *invalid credentials* means either that the user name and/or password is incorrect, for example because the password was changed or expired, or that the account authorization has expired, for example due to logging out. If the password is incorrect/expired, you will have to update the password in the account and/or identity settings. If the account authorization has expired, you will have to select the account again. You will likely need to save the associated identity again as well. In the case of a Gmail account the error *Invalid credentials (Failure)* can be the result of *accounts.google.com* being blocked for the Android account manager, for example due to using a VPN, firewall, ad blocker, or similar. So, try to disable all VPN based apps or allow this address.
**(88) How can I use a Yahoo/AT&T, AOL or Sky account?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq88) The preferred way to set up a Yahoo account is by using the quick setup wizard, which will use OAuth instead of a password and is therefore safer (and easier as well). To authorize a Yahoo/AT&T, AOL, or Sky account you need to use an app password instead of your normal account password. For instructions about how to create an app password, please see here: * [for Yahoo/AT&T](https://help.yahoo.com/kb/generate-third-party-passwords-sln15241.html) * [for AOL](https://help.aol.com/articles/Create-and-manage-app-password) * [for Sky](https://www.sky.com/help/articles/getting-started-with-sky-yahoo-mail) (under *Other email apps*) Please see [this FAQ](#user-content-faq111) about OAuth support. Note that Yahoo, AOL, and Sky do not support standard push messages. The Yahoo email app uses a proprietary, undocumented protocol for push messages. Push messages require [IMAP IDLE](https://en.wikipedia.org/wiki/IMAP_IDLE) and the Yahoo email server does not report IDLE as capability: ``` Y1 CAPABILITY * CAPABILITY IMAP4rev1 ID MOVE NAMESPACE XYMHIGHESTMODSEQ UIDPLUS LITERAL+ CHILDREN X-MSG-EXT UNSELECT OBJECTID Y1 OK CAPABILITY completed ```
**(89) How can I send plain text only messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq89) By default FairEmail sends each message both as plain text and as HTML formatted text because almost every receiver expects formatted messages these days. If you want/need to send plain text only messages, you can enable this in the send options. You can enable/disable sending plain text only messages in the send dialog on a case by case basis as well. If you disabled the send dialog, you can long press the *Send* button to show it again.
**(90) Why are some texts linked while not being a link?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq90) FairEmail will automatically link not linked web links (http and https) and not linked email addresses (mailto) for your convenience. However, texts and links are not easily distinguished, especially not with lots of [top level domains](https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains) being words. This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links. Links for the tel, geo, rtsp and xmpp protocols will be recognized too, but links for less usual or less safe protocols like telnet and ftp will not be recognized. The regex to recognize links is already *very* complex and adding more protocols will make it only slower and possibly cause errors. Note that original messages are shown exactly as they are, which means also that links are not automatically added.
**~~(91) Can you add periodical synchronization to save battery power?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq91) ~~Synchronizing messages is an expensive proces because the local and remote messages need to be compared,~~ ~~so periodically synchronizing messages will not result in saving battery power, more likely the contrary.~~ ~~See [this FAQ](#user-content-faq39) about optimizing battery usage.~~
**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq92) Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client. Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices. Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client. Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to. Spam filtering based on message headers might have been feasible, but unfortunately this technique is [patented by Microsoft](https://patents.google.com/patent/US7543076). Recent versions of FairEmail can filter spam to a certain extent using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this. Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#user-content-faq71) too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder. Note that the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts. Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are. If you are wondering why a message was moved into the spam folder, these are all possible reasons: * The email server of your email provider moved the message into the spam folder. The app can't undo this automatically because this can result in an endless loop. * The message classifier (miscellaneous settings tab page) moved the message into the spam folder. * A filter rule (navigation menu = left side menu of the start screen), for example a block domain name rule, moved the message into the spam folder. * An email address or a network address is on a block list (receive settings tab page). If you receive a lot of spam messages in your inbox, the best you can do is to contact the email provider to ask if spam filtering can be improved. Also, FairEmail can show a small red warning flag when DKIM, SPF or [DMARC](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server. You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings. FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server. This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly. If the domain name of the sender and the domain name of the reply address differ, the warning flag will be shown too because this is most often the case with phishing messages. If desired, this can be disabled in the receive settings (since version 1.1506). If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated. The sender might use [this tool](https://www.mail-tester.com/) to check authentication and other things.
**(93) Can you allow installation/data storage on external storage media (sdcard)?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq93) FairEmail uses services and alarms, provides widgets and listens for the boot completed event to be started on device start, so it is not possible to store the app on external storage media, like an sdcard. See also [here](https://developer.android.com/guide/topics/data/install-location). Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe. See [here](https://developer.android.com/training/data-storage) for the details. Instead, consider to use [adoptable storage](https://source.android.com/devices/storage/adoptable). Since version 1.1829 is it possible to store attachments to external storage space private to the app (except for file managers) via an option in the debug panel. You can enable the debug panel by enabling debug mode in the miscellaneous settings (last option). To prevent ongoing operations from storing attachments at the old location you should disable receiving messages in the receive settings and wait until all operations have been completed before changing this option. Please be aware that removing the storage space will inevitably result in problems, which is one of the reasons why this option is hidden. When needed you can save (raw) messages via the three-dots menu just above the message text and save attachments by tapping on the floppy icon. If you need to save on storage space, you can limit the number of days messages are being synchronized and kept on your device and disable downloading and storing of message texts and attachments (which means only message headers will be stored). You can change these settings by long pressing a folder in the folder list and selecting *Edit properties*.
**(94) What does the red/orange stripe at the end of the header mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq94) The red/orange stripe at the left side of the header means that the DKIM, SPF or DMARC authentication failed. See also [this FAQ](#user-content-faq92).
**(95) Why are not all apps shown when selecting an attachment or image?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq95) For privacy and security reasons FairEmail does not have permissions to directly access files, instead the Storage Access Framework, available and recommended since Android 4.4 KitKat (released in 2013), is used to select files. If an app is listed depends on if the app implements a [document provider](https://developer.android.com/guide/topics/providers/document-provider). If the app is not listed, you might need to ask the developer of the app to add support for the Storage Access Framework. Android Q will make it harder and maybe even impossible to directly access files, see [here](https://developer.android.com/preview/privacy/scoped-storage) and [here](https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/) for more details. If you use MIUI, please make sure [MIUI optimization](https://android.stackexchange.com/questions/191228/what-is-miui-optimization) is enabled in the developer settings. You can enable the developer options by tapping a few times on the MIUI version number in the settings, About phone.
**(96) Where can I find the IMAP and SMTP settings?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq96) The IMAP settings are part of the (custom) account settings and the SMTP settings are part of the identity settings.
**(97) What is 'cleanup'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq97) About each four hours FairEmail runs a cleanup job that: * Removes old message texts * Removes old attachment files * Removes old image files * Removes old local contacts * Removes old log entries Note that the cleanup job will only run when the synchronize service is active.
**(98) Why can I still pick contacts after revoking contacts permissions?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq98) After revoking contacts permissions Android does not allow FairEmail access to your contacts anymore. However, picking contacts is delegated to and done by Android and not by FairEmail, so this will still be possible without contacts permissions.
**(99) Can you add a rich text or markdown editor?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq99) FairEmail provides common text formatting (bold, italic, underline, text size and color) via a toolbar that appears after selecting some text. A [Rich text](https://en.wikipedia.org/wiki/Formatted_text) or [Markdown](https://en.wikipedia.org/wiki/Markdown) editor would not be used by many people on a small mobile device and, more important, Android doesn't support a rich text editor and most rich text editor open source projects are abandoned. See [here](https://forum.xda-developers.com/showpost.php?p=79061829&postcount=4919) for some more details about this.
**(100) How can I synchronize Gmail categories?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq100) You can synchronize Gmail categories by creating filters to label categorized messages: * Create a new filter via Gmail > Settings wheel > See all settings > Filters and Blocked Addresses > Create a new filter * Enter a category search (see below) in the *Has the words* field and click *Create filter* * Check *Apply the label* and select a label and click *Create filter* Possible categories: ``` category:social category:updates category:forums category:promotions ``` Documentation: [see here](https://support.google.com/mail/answer/7190). Unfortunately, this is not possible for the snoozed messages folder. You can use *Force sync* in the three-dots menu of the unified inbox to let FairEmail synchronize the folder list again and you can long press the folders to enable synchronization.
**(101) What does the blue/orange dot at the bottom of the conversations mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq101) The dot shows the relative position of the conversation in the message list. The dot will be show orange when the conversation is the first or last in the message list, else it will be blue. The dot is meant as an aid when swiping left/right to go to the previous/next conversation. The dot is disabled by default and can be enabled with the display settings *Show relative conversation position with a dot*.
**(102) How can I enable auto rotation of images?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq102) Images will automatically be rotated when automatic resizing of images is enabled in the settings (enabled by default). However, automatic rotating depends on the [Exif](https://en.wikipedia.org/wiki/Exif) information to be present and to be correct, which is not always the case. Particularly not when taking a photo with a camara app from FairEmail. Note that only [JPEG](https://en.wikipedia.org/wiki/JPEG) and [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) images can contain Exif information.
**(104) What do I need to know about error reporting?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq104) * Error reports will help improve FairEmail * Error reporting is optional and opt-in * Error reporting can be enabled/disabled via the *miscellaneous* settings tab page * Error reports will automatically be sent anonymously to [Bugsnag](https://www.bugsnag.com/) * [Telemetry](https://docs.bugsnag.com/platforms/android/configuration-options/#telemetry) is always disabled * Bugsnag for Android is [open source](https://github.com/bugsnag/bugsnag-android) * See [here](https://docs.bugsnag.com/platforms/android/automatically-captured-data/) about what data will be sent in case of errors * See [here](https://docs.bugsnag.com/legal/privacy-policy/) for the privacy policy of Bugsnag * Error reports will be sent to *sessions.bugsnag.com:443* and *notify.bugsnag.com:443* Error reports have helped to find otherwise hard to find bugs and therefore improve the overall stability of the app.
**(105) How does the roam-like-at-home option work?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq105) FairEmail will check if the country code of the SIM card and the country code of the network are in the [EU roam-like-at-home countries](https://en.wikipedia.org/wiki/European_Union_roaming_regulations#Territorial_extent) and assumes no roaming if the country codes are equal and the advanced roam-like-at-home option is enabled. So, you don't have to disable this option if you don't have an EU SIM or are not connected to an EU network.
**(106) Which launchers can show a badge count with the number of unread messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq106) Please [see here](https://github.com/leolin310148/ShortcutBadger#supported-launchers) for a list of launchers which can show the number of unread messages. Standard Android [does not support this](https://developer.android.com/training/notify-user/badges). Note that Nova Launcher requires Tesla Unread, which is [not supported anymore](https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415). Note that the notification setting *Show launcher icon with number of new messages* needs to be enabled (default enabled). Only *new* unread messages in folders set to show new message notifications will be counted, so messages marked unread again and messages in folders set to not show new message notification will not be counted. Depending on what you want, the notification settings *Let the number of new messages match the number of notifications* needs to be enabled (default disabled). When enabled the badge count will be the same as the number of new message notifications. When disabled the badge count will be the number of unread messages, independent if they are shown in a notification or are new. This feature depends on support of your launcher. FairEmail merely 'broadcasts' the number of unread messages using the ShortcutBadger library. If it doesn't work, this cannot be fixed by changes in FairEmail. If you are using Nova launcher and you want to show the number of notifications in the launcher icon (maximum 10), you'll need to enable *Notification access* in the Android *Special app access* settings for Nova launcher on recent Android versions. Some launchers display a dot or a '1' for [the monitoring notification](#user-content-faq2), despite FairEmail explicitly requesting not to show a *badge* for this notification. This could be caused by a bug in the launcher app or in your Android version. Please double check if the notification dot (badge) is disabled for the receive (service) notification channel. You can go to the right notification channel settings via the notification settings of FairEmail. This might not be obvious, but you can tap on the channel name for more settings. FairEmail does send a new message count *broadcast* intent as well: ``` eu.faircode.email.NEW_MESSAGE_COUNT ``` The number of new, unread messages will be in an integer "*count*" parameter.
**(107) How do I use colored stars?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq107) You can set a colored star via the *more* message menu, via multiple selection (started by long pressing a message), by long pressing a star in a conversation or automatically by using [rules](#user-content-faq71). You need to know that colored stars are not supported by the IMAP protocol and can therefore not be synchronized to an email server. This means that colored stars will not be visible in other email clients and will be lost on downloading messages again. However, the stars (without color) will be synchronized and will be visible in other email clients, when supported. Some email clients use IMAP keywords for colors. However, not all servers support IMAP keywords and besides that there are no standard keywords for colors.
**~~(108) Can you add permanently delete messages from any folder?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq108) ~~When you delete messages from a folder the messages will be moved to the trash folder, so you have a chance to restore the messages.~~ ~~You can permanently delete messages from the trash folder.~~ ~~Permanently delete messages from other folders would defeat the purpose of the trash folder, so this will not be added.~~
**~~(109) Why is 'select account' available in official versions only?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq109) ~~Using *select account* to select and authorize Google accounts require special permission from Google for security and privacy reasons.~~ ~~This special permission can only be acquired for apps a developer manages and is responsible for.~~ ~~Third party builds, like the F-Droid builds, are managed by third parties and are the responsibility of these third parties.~~ ~~So, only these third parties can acquire the required permission from Google.~~ ~~Since these third parties do not actually support FairEmail, they are most likely not going to request the required permission.~~ ~~You can solve this in two ways:~~ * ~~Switch to the official version of FairEmail, see [here](https://github.com/M66B/FairEmail/blob/master/README.md#downloads) for the options~~ * ~~Use app specific passwords, see [this FAQ](#user-content-faq6)~~ ~~Using *select account* in third party builds is not possible in recent versions anymore.~~ ~~In older versions this was possible, but it will now result in the error *UNREGISTERED_ON_API_CONSOLE*.~~
**(110) Why are (some) messages empty and/or attachments corrupt?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq110) Empty messages and/or corrupt attachments are probably being caused by a bug in the server software. Older Microsoft Exchange software is known to cause this problem. Mostly you can workaround this by disabling *Partial fetch* in the advanced account settings: Settings > Manual setup > Accounts > tap account > tap advanced > Partial fetch > uncheck After disabling this setting, you can use the message 'more' (three dots) menu to 'resync' empty messages. Alternatively, you can *Delete local messages* by long pressing the folder(s) in the folder list and synchronize all messages again. Disabling *Partial fetch* will result in more memory usage.
**(111) Is OAuth supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq111) OAuth for Gmail is supported via the quick setup wizard. ~~The Android account manager will be used to fetch and refresh OAuth tokens for selected on-device accounts.~~ ~~OAuth for non on-device accounts is not supported~~ ~~because Google requires a [yearly security audit](https://support.google.com/cloud/answer/9110914) ($15,000 to $75,000) for this.~~ ~~Since FairEmail is basically offered free of charge, it is not an option to pay such an amount annually for a security audit.~~ ~~You can read more about this [here](https://www.theregister.com/2019/02/11/google_gmail_developer/).~~ OAuth for Outlook/Office 365, Yahoo, Mail.ru and Yandex is supported via the quick setup wizard. The OAuth [jump page](https://oauth.faircode.eu/) exists for when [Android App Links](https://developer.android.com/training/app-links/verify-site-associations) are not available, for example when using a non Play store version of the app, or do not work for some reason. OAuth is not supported for third party builds like the F-Droid build, please [see here](#user-content-faq147) about why not. Since version 1.1859 there is support for custom OAuth. To use custom OAuth, an XML file containing the server and OAuth data, like the client secret, should be created and imported. Please [see here](https://github.com/M66B/FairEmail/blob/master/app/src/main/res/xml/providers.xml) about how the XML file should look like. The XML file can be imported via a button in the debug panel of the miscellaneous settings of the app. To show the debug panel, debug mode mode should temporarily be enabled. After importing, you can use the quick setup wizard to configure an account.
**(112) Which email provider do you recommend?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq112) FairEmail is an email client only, so you need to bring your own email address. Note that this is clearly mentioned in the app description. There are plenty of email providers to choose from. Which email provider is best for you depends on your wishes/requirements. Please see these websites for lists of privacy oriented email providers with advantages and disadvantages: * [Restore privacy](https://restoreprivacy.com/secure-email/) * [Privacy Guides](https://www.privacyguides.org/email/) * [Privacy Tools](https://www.privacytools.io/providers/email/) **Important**: Some providers, like ProtonMail and Tutanota, use proprietary email protocols, which make it impossible to use third party email apps. Please see [this FAQ](#user-content-faq129) for more information. Using your own (custom) domain name, which is supported by most email providers, will make it easier to switch to another email provider.
**(113) How does biometric authentication work?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq113) If your device has a biometric sensor, for example a fingerprint sensor, you can enable/disable biometric authentication in the navigation (hamburger) menu of the settings screen. When enabled FairEmail will require biometric authentication after a period of inactivity or after the screen has been turned off while FairEmail was running. Activity is navigation within FairEmail, for example opening a conversation thread. The inactivity period duration can be configured in the miscellaneous settings. When biometric authentication is enabled new message notifications will not show any content and FairEmail won't be visible on the Android recents screen. Biometric authentication is meant to prevent others from seeing your messages only. FairEmail relies on device encryption for data encryption, see also [this FAQ](#user-content-faq37). Biometric authentication is a pro feature.
**(114) Can you add an import for the settings of other email apps?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq114) The format of the settings files of most other email apps is not documented, so this is difficult. Sometimes it is possible to reverse engineer the format, but as soon as the settings format changes things will break. Also, settings are often incompatible. For example, FairEmail has unlike most other email apps settings for the number of days to synchronize messages and for the number of days to keep messages, mainly to save on battery usage. Moreover, setting up an account/identity with the quick setup wizard is simple, so it is not really worth the effort.
**~~(115) Can you add email address chips?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq115) ~~Email address [chips](https://material.io/design/components/chips.html) look nice, but cannot be edited,~~ ~~which is quite inconvenient when you made a typo in an email address.~~ ~~Note that FairEmail will select the address only when long pressing an address, which makes it easy to delete an address.~~ ~~Chips are not suitable for showing in a list~~ ~~and since the message header in a list should look similar to the message header of the message view it is not an option to use chips for viewing messages.~~ ~~Reverted [commit](https://github.com/M66B/FairEmail/commit/2c80c25b8aa75af2287f471b882ec87d5a5a5015).~~
**~~(116) How can I show images in messages from trusted senders by default?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq116) ~~You can show images in messages from trusted senders by default by enabled the display setting *Automatically show images for known contacts*.~~ ~~Contacts in the Android contacts list are considered to be known and trusted,~~ ~~unless the contact is in the group / has the label '*Untrusted*' (case insensitive).~~
**(117) How can I restore a purchase (on another device) ?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq117) First of all, a purchase will be available on all devices logged into the same Google account, *if* (this is important) the app is installed via the same Google account too. You can select the account in the Play store app by tapping on the avatar at the top right. Google manages all purchases, so as a developer I have little control over purchases. So, basically the only thing I can do, is give some advice: * Make sure you have an active, working internet connection, and turn off any VPN based app because it might prevent the Play store from checking purchases * Make sure you are logged in with the right Google account and that there is nothing wrong with your Google account * Make sure you installed FairEmail via the right Google account if you configured multiple Google accounts on your device (you might need to reinstall the app) * Make sure the Play store app is up to date, please [see here](https://support.google.com/googleplay/answer/1050566?hl=en) * Open the Play store app and wait at least a minute to give it time to synchronize with the Google servers * Open FairEmail and navigate to the pro features screen to let FairEmail check the purchases; sometimes it help to tap the *buy* button You can also try to clear the cache of the Play store app via the Android apps settings. Restarting the device might be necessary to let the Play store recognize the purchase correctly. Note that: * If you get *ITEM_ALREADY_OWNED*, the Play store app probably needs to be updated, please [see here](https://support.google.com/googleplay/answer/1050566?hl=en) * If you get *BILLING_UNAVAILABLE Google Play In-app Billing API version is less than 3*, the Play store app might not be logged into the account used to install the app * Purchases are stored in the Google cloud and cannot get lost * There is no time limit on purchases, so they cannot expire * Google does not expose details (name, e-mail, etc) about buyers to developers * An app like FairEmail cannot select which Google account to use * It may take a while until the Play store app has synchronized a purchase to another device * Play Store purchases cannot be used without the Play Store app/services * Play Store purchases cannot be transferred to another account * You can't restore purchases with [microG](https://microg.org/) Please [see here](https://support.google.com/googleplay/answer/4646404) about how to add, remove, or edit your Google Play payment method. If you cannot solve the problem with the purchase, you will have to contact Google about it.
**(118) What does 'Remove tracking parameters' exactly?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq118) Checking *Remove tracking parameters* will remove all [UTM parameters](https://en.wikipedia.org/wiki/UTM_parameters) from a link.
**~~(119) Can you add colors to the unified inbox widget?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq119) ~~The widget is designed to look good on most home/launcher screens by making it monochrome and by using a half transparent background.~~ ~~This way the widget will nicely blend in, while still being properly readable.~~ ~~Adding colors will cause problems with some backgrounds and will cause readability problems, which is why this won't be added.~~ Due to Android limitations it is not possible to dynamically set the opacity of the background and to have rounded corners at the same time.
**(120) Why are new message notifications not removed on opening the app?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq120) New message notifications will be removed on swiping notifications away or on marking the associated messages read. Opening the app will not remove new message notifications. This gives you a choice to leave new message notifications as a reminder that there are still unread messages. On Android 7 Nougat and later new message notifications will be [grouped](https://developer.android.com/training/notify-user/group). Tapping on the summary notification will open the unified inbox. The summary notification can be expanded to view individual new message notifications. Tapping on an individual new message notification will open the conversation the message it is part of. See [this FAQ](#user-content-faq70) about when messages in a conversation will be auto expanded and marked read.
**(121) How are messages grouped into a conversation?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq121) By default FairEmail groups messages in conversations. This can be turned of in the display settings. FairEmail groups messages based on the standard *Message-ID*, *In-Reply-To* and *References* headers. FairEmail does not group on other criteria, like the subject, because this could result in grouping unrelated messages and would be at the expense of increased battery usage.
**~~(122) Why is the recipient name/email address show with a warning color?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq122) ~~The recipient name and/or email address in the addresses section will be shown in a warning color~~ ~~when the sender domain name and the domain name of the *to* address do not match.~~ ~~Mostly this indicates that the message was received *via* an account with another email address.~~
**(123) What will happen when FairEmail cannot connect to an email server?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq123) If FairEmail cannot connect to an email server to synchronize messages, for example if the internet connection is bad or a firewall or a VPN is blocking the connection, FairEmail will retry one time after waiting 8 seconds while keeping the device awake (=use battery power). If this fails, FairEmail will schedule an alarm to retry after 5, 15, 30 and eventually every 60 minutes and let the device sleep (=no battery usage). By temporarily enabling debug mode in the miscellaneous settings, you can disable this logarithmic back-off scheme (since version 1.1855). This will result in using a linear back-off scheme, which means that after each successive failure the waiting time will be increased by 1 minute the first 5 minutes and thereafter by 5 minutes up to 60 minutes. Note that [Android doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) does not allow to wake the device earlier than after 15 minutes when doze mode is active. *Force sync* in the three-dots menu of the unified inbox can be used to let FairEmail attempt to reconnect without waiting. Sending messages will be retried on connectivity changes only (reconnecting to the same network or connecting to another network) to prevent the email server from blocking the connection permanently. You can pull down the outbox to retry manually. Note that sending will not be retried in case of authentication problems and when the server rejected the message. In this case you can pull down the outbox to try again.
**(124) Why do I get 'Message too large or too complex to display'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq124) The message *Message too large or too complex to display* will be shown if there are more than 100,000 characters or more than 500 links in a message. Reformatting and displaying such messages will take too long. You can try to use the original message view, powered by the browser, instead.
**(125) What are the current experimental features?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq125) *Send hard bounce (version 1.1477+)* Send a [Delivery Status Notification](https://tools.ietf.org/html/rfc3464) (=hard bounce) via the reply/answer menu. Hard bounces will mostly be processed automatically because they affect the reputation of the email provider. The bounce address (=*Return-Path* header) is mostly very specific, so the email server can determine the sending account. Some email servers, reportedly the Outlook.com email server, respond with a hard bounce to a hard bounce. In other words, hard bounces are being rejected. For some background, see for [this Wikipedia article](https://en.wikipedia.org/wiki/Bounce_message).
*Resend (version 1.1788+)* Resend a message as defined in [rfc2822 section 3.6.6](https://datatracker.ietf.org/doc/html/rfc2822#section-3.6.6) via the reply/answer menu. To resend a message, the original message headers are required. You can enable downloading of messages headers for all messages in the connection settings of the app. Alternative, you can show messages headers via the horizontal three-dots menu just above the message text to download the message headers for a single message. The resend menu item will be shown grayed (dimmed) if the message headers are not available (yet). Remarks: * Messages to, CC or BCC *undisclosed-recipients:* cannot be resend * The original subject is sent as-is, unless it is being changed * The original message text will be sent as-is, unless text is being entered * The original attachments are sent as they are, unless attachments are being added or removed * Default CC and BCC addresses will not be applied * Read and delivery receipts will be requested when enabled, they could go to the original sender or to you * The email server might refuse resent messages * DKIM, SPF and DMARC will likely fail, often causing resent messages to be considered as spam
*Process delivery/read receipt (version 1.1797+)* On receiving a delivery or read receipt, the related message will be looked up in the sent messages folder and the following keywords will be set depending on the contents of the report: ``` $Delivered $NotDelivered $Displayed $NotDisplayed ``` * Delivered: action = *delivered*, *relayed*, or *expanded*, [see here](https://datatracker.ietf.org/doc/html/rfc3464#section-2.3.3) * Displayed: disposition = *displayed*, [see here](https://datatracker.ietf.org/doc/html/rfc3798#section-3.2.6) It is probably a good idea to enable *Show keywords in message header* in the display settings. Note that the email server needs to support IMAP flags (keywords) for this feature. Filter rules will be applied to the received receipt, so it is possible to move/archive the receipt. See [this FAQ](#user-content-faq71) for a header condition to recognize receipts.
*Block toolbar (version 1.1967+)* When enabled in the three-dots overflow menu of the message editor, a toolbar to perform operations (align text, insert list, indent text, insert blockquote) on a block of text (consecutive non-empty lines) will be shown.
**(126) Can message previews be sent to my wearable?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq126) FairEmail fetches a message in two steps: 1. Fetch message headers 1. Fetch message text and attachments Directly after the first step new messages will be notified. However, only until after the second step the message text will be available. FairEmail updates exiting notifications with a preview of the message text, but unfortunately wearable notifications cannot be updated. Since there is no guarantee that a message text will always be fetched directly after a message header, it is not possible to guarantee that a new message notification with a preview text will always be sent to a wearable. If you think this is good enough, you can enable the notification option *Only send notifications with a message preview to wearables* and if this does not work, you can try to enable the notification option *Show notifications with a preview text only*. Note that this applies to wearables not showing a preview text too, even when the Android Wear app says the notification has been sent (bridged). If you want to have the full message text sent to your wearable, you can enable the notification option *Preview all text*. Note that some wearables are known to crash with this option enabled. If you use a Samsung wearable with the Galaxy Wearable (Samsung Gear) app, you might need to enable notifications for FairEmail when the setting *Notifications*, *Apps installed in the future* is turned off in this app. Some companion apps ignore [local only](https://developer.android.com/training/wearables/notifications/bridger#non-bridged) notifications, causing the summary notification (*nnn new messages*) to be bridged. Unfortunately, it is not possible to workaround this problem.
**(127) How can I fix 'Syntactically invalid HELO argument(s)'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq127) The error *... Syntactically invalid HELO argument(s) ...* means that the SMTP server rejected the local IP address or host name. You can likely fix this error by enabling or disabling the advanced indentity option *Use local IP address instead of host name*.
**(128) How can I reset asked questions, for example to show images?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq128) You can reset asked questions via the three dots overflow menu in the miscellaneous settings.
**(129) Are ProtonMail, Tutanota, etc supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq129) **ProtonMail** uses a proprietary email protocol and [does not directly support IMAP](https://protonmail.com/support/knowledge-base/imap-smtp-and-pop3-setup/), so you cannot use FairEmail or any other Android email client to access ProtonMail. **Tutanota** uses a proprietary email protocol and [does not support IMAP](https://tutanota.com/faq/#imap), so you cannot use FairEmail or any other email client to access Tutanota. **Cyberfear** does not support IMAP, so you'll need to manually configure a POP3 account.
**(130) What does message error ... mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq130) If you don't understand an error, please [contact me](https://contact.faircode.eu/?product=fairemailsupport) for support. The warning *No server found at ...* means that there was no email server registered at the indicated domain name. Replying to the message might not be possible and might result in an error. This could indicate a falsified email address and/or spam. The error *... ParseException ...* means that there is a problem with a received message, likely caused by a bug in the sending software. FairEmail will workaround this is in most cases, so this message can mostly be considered as a warning instead of an error. The error *...SendFailedException...* means that there was a problem while sending a message. The error will almost always include a reason. Common reasons are that the message was too big or that one or more recipient addresses were invalid. The warning *Message too large to fit into the available memory* means that the message was larger than 10 MiB. Even if your device has plenty of storage space Android provides limited working memory to apps, which limits the size of messages that can be handled. Please see [here](#user-content-faq22) for other error messages.
**(131) Can you change the direction for swiping to previous/next message?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq131) If you read from left to right, swiping to the left will show the next message. Similarly, if you read from right to left, swiping to the right will show the next message. This behavior seems quite natural to me, also because it is similar to turning pages. Anyway, there is a behavior setting to reverse the swipe direction.
**(132) Why are new message notifications silent?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq132) Notifications are silent by default on some MIUI versions. Please see [here](http://en.miui.com/thread-3930694-1-1.html) how you can fix this. There is a bug in some Android versions causing [setOnlyAlertOnce](https://developer.android.com/reference/android/app/Notification.Builder#setOnlyAlertOnce(boolean)) to mute notifications. Since FairEmail shows new message notifications right after fetching the message headers and FairEmail needs to update new message notifications after fetching the message text later, this cannot be fixed or worked around by FairEmail. Android might rate limit the notification sound, which can cause some new message notifications to be silent.
**(133) Why is ActiveSync not supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq133) The Microsoft Exchange ActiveSync protocol [is patented](https://en.wikipedia.org/wiki/Exchange_ActiveSync#Licensing) and can therefore not be supported. For this reason you won't find many, if any, other email clients supporting ActiveSync. Note that the desciption of FairEmail starts with the remark that non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync are not supported.
**(134) Can you add leave messages on the server?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq134) *POP3* In the account settings (Settings, tap Manual setup, tap Accounts, tap account) you can enable *Leave messages on server* and *Leave deleted messages on server*. *IMAP* Since the IMAP protocol is meant to synchronize two ways, trashing (=move to trash) and (permanently) deleting messages will be performed on the email server too, so that the message list is the same for all connected clients. Deleting a messages from the device only won't work because it would be synchronized again later. However, FairEmail supports hiding messages, either via the three-dots menu in the action bar just above the message text (you can configure a button for this via the same menu) or by multiple selecting messages in the message list. Basically this is the same as "leave on server" of the POP3 protocol with the advantage that you can show the messages again when needed. Alternatively, you can disable AUTO EXPUNGE, which will result in marking messages being deleted on the server (by setting the *deleted* flag), but not expunging (deleting) them. You can find this option in the debug panel, which can be shown by (temporarily) enabling debug mode in the miscellaneous settings. Note that it is possible to set the swipe left or right action to hide a message. There is a button in the behavior settings to quickly configure the swipe left and right actions for all IMAP account.
**(135) Why are trashed messages and drafts shown in conversations?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq135) Individual messages will rarely be trashed and mostly this happens by accident. Showing trashed messages in conversations makes it easier to find them back. You can permanently delete a message using the message three-dots *delete* menu, which will remove the message from the conversation. Note that this irreversible. Similarly, drafts are shown in conversations to find them back in the context where they belong. It is easy to read through the received messages before continuing to write the draft later.
**(136) How can I delete an account/identity/folder?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq136) Deleting an account/identity/folder is a little bit hidden to prevent accidents. * Account: Settings > Manual setup > Accounts > tap account * Identity: Settings > Manual setup > Identities > tap identity * Folder: Long press the folder in the folder list > Edit properties In the three-dots overflow menu at the top right there is an item to delete the account/identity/folder.
**(137) How can I reset 'Don't ask again'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq137) You can reset all questions set to be not asked again in the miscellaneous settings.
**(138) Can you add calendar/contact/tasks/notes management?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq138) Calendar, contact, task and note management can better be done by a separate, specialized app. Note that FairEmail is a specialized email app, not an office suite. Also, I prefer to do a few things very well, instead of many things only half. Moreover, from a security perspective, it is not a good idea to grant many permissions to a single app. You are advised to use the excellent, open source [DAVx⁵](https://f-droid.org/packages/at.bitfire.davdroid/) app to synchronize/manage your calendars/contacts. If you want to synchronize Outlook contacts and you have access to Google Workspace, please [see here](https://support.google.com/a/users/answer/156595) about how you can set up contact syncing. Most providers support exporting your contacts. Please [see here](https://support.google.com/contacts/answer/1069522) about how you can import contacts if synchronizing is not possible. Note that FairEmail does support replying to calendar invites (a pro feature) and adding calendar invites to your personal calendar.
**(139) How do I fix 'User is authenticated but not connected'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq139) The confusing Microsoft specific server error *User is authenticated but not connected* might occur if: * External access is administratively disabled, please see [this article](https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/client-access-rules/client-access-rules) about how an administrator can enable it again * SMTP is administratively disabled, please see [this article](https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission) about how an administrator can enable it again * Required server components are disabled, please see [this article](https://learn.microsoft.com/en-us/exchange/troubleshoot/user-and-shared-mailboxes/pop3-imap-owa-activesync-office-365) about enabling IMAP, MAPI, etc. * Push messages are enabled for too many folders: see [this FAQ](#user-content-faq23) for more information and a workaround * There were too many login attempts in a too short time, for example by using multiple email clients at the same time * An ad blocker or DNS changer is being used * There is a problem with the Exchange server license: it might be expired or for another server edition * An alias email address is being used as username instead of the primary email address * An incorrect login scheme is being used for a shared mailbox: the right scheme is *username@domain\SharedMailboxAlias* The shared mailbox alias will mostly be the email address of the shared account, like this: ``` you@example.com\shared@example.com ``` Note that it should be a backslash and not a forward slash. The Outlook/Office 365 quick setup wizard supports setting up shared mailboxes. When using a shared mailbox, you might want to enable the option *Synchronize shared folder lists* in the receive settings. Sometimes it helps to use the *Other provider* wizard instead of the *Outlook/Office 365* wizard. You might need an app password for this, please see [this FAQ](#user-content-faq14).
**(140) Why does the message text contain strange characters?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq140) Displaying strange characters is almost always caused by specifying no or an invalid character encoding by the sending software. FairEmail will assume [ISO 8859-1](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) when no character set or when [US-ASCII](https://en.wikipedia.org/wiki/ASCII) was specified. Other than that there is no way to reliably determine the correct character encoding automatically, so this cannot be fixed by FairEmail. The right action is to complain to the sender.
**(141) How can I fix 'A drafts folder is required to send messages'?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq141) To store draft messages a drafts folder is required. In most cases FairEmail will automatically select the drafts folders on adding an account based on [the attributes](https://www.iana.org/assignments/imap-mailbox-name-attributes/imap-mailbox-name-attributes.xhtml) the email server sends. However, some email servers are not configured properly and do not send these attributes. In this case FairEmail tries to identify the drafts folder by name, but this might fail if the drafts folder has an unusual name or is not present at all. You can fix this problem by manually selecting the drafts folder in the account settings (Settings, tap Manual setup, tap Accounts, tap account, at the bottom). If there is no drafts folder at all, you can create a drafts folder by tapping on the '+' button in the folder list of the account (tap on the account name in the navigation menu). Some providers, like Gmail, allow enabling/disabling IMAP for individual folders. So, if a folder is not visible, you might need to enable IMAP for the folder. Quick link for Gmail (will work on a desktop computer only): [https://mail.google.com/mail/u/0/#settings/labels](https://mail.google.com/mail/u/0/#settings/labels)
**(142) How can I store sent messages in the inbox?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq142) Generally, it is not a good idea to store sent messages in the inbox because this is hard to undo and could be incompatible with other email clients. That said, FairEmail is able to properly handle sent messages in the inbox. FairEmail will mark outgoing messages with a sent messages icon for example. The best solution would be to enable showing the sent folder in the unified inbox by long pressing the sent folder in the folder list and enabling *Show in unified inbox*. This way all messages can stay where they belong, while allowing to see both incoming and outgoing messages at one place. If this is not an option, you can [create a rule](#user-content-faq71) to automatically move sent messages to the inbox or set a default CC/BCC address in the advanced identity settings (via the manual setup in the main setup screen) to send yourself a copy.
**~~(143) Can you add a trash folder for POP3 accounts?~~** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq143) [POP3](https://en.wikipedia.org/wiki/Post_Office_Protocol) is a very limited protocol. Basically only messages can be downloaded and deleted from the inbox. It is not even possible to mark a message read. Since POP3 does not allow access to the trash folder at all, there is no way to restore trashed messages. Note that you can hide messages and search for hidden messages, which is similar to a local trash folder, without suggesting that trashed messages can be restored, while this is actually not possible. Version 1.1082 added a local trash folder. Note that trashing a message will permanently remove it from the server and that trashed messages cannot be restored to the server anymore.
**(144) How can I record voice notes?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq144) To record voice notes you can press this icon in the bottom action bar of the message composer:  This requires a compatible audio recorder app to be installed. In particular [this common intent](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media.html#RECORD_SOUND_ACTION) needs to be supported. For example [this audio recorder](https://f-droid.org/app/com.github.axet.audiorecorder) is compatible. Voice notes will automatically be attached.
**(145) How can I set a notification sound for an account, folder, sender or condition?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq145) Account: * Version 1.1927-: enable *Separate notifications* in the advanced account settings * Version 1.1927+: long press the account in the account list and select *Create notification channel* * Long press the account in the account list and select *Edit notification channel* to change the notification sound To go to the account list: navigation menu (left side menu), tap *Settings*, tap *Manual setup and account options* and tap *Accounts*.
To go to the advanced account settings from the account list: tap on the account and tap on *Advanced*. Folder: * Long press the folder in the folder list and select *Notify on new messages* * Long press the folder in the folder list and select *Create notification channel* * Long press the folder in the folder list and select *Edit notification channel* to change the notification sound To go to the folder list: tap on the account name in the navigation menu (left side menu). Sender: * Open a message from the sender and expand it * Expand the addresses section by tapping on the down arrow * Tap on the bell icon to create or edit a notification channel and to change the notification sound Conditional: (since version 1.1803; experimental) * Long press the folder (inbox) in the folder list and select *Edit rules* * Add a rule with the big 'plus' button at the bottom right * Configure a rule condition, select *Play sound* as rule action and select a sound * For more information about filter rules, please [see here](#user-content-faq71) The order of precendence is: conditional sound, sender sound, folder sound, account sound and (default) notification sound. Setting a notification sound for an account, folder or sender requires Android 8 Oreo or later and is a pro feature.
**(146) How can I fix incorrect message times?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq146) Since the sent date/time is optional and can be manipulated by the sender, FairEmail uses the server received date/time by default. Sometimes the server received date/time is incorrect, mostly because messages were incorrectly imported from another server and sometimes due to a bug in the email server. In these rare cases, it is possible to let FairEmail use either the date/time from the *Date* header (sent time) or from the *Received* header as a workaround. This can be changed in the advanced account settings: Settings, tap Manual setup, tap Accounts, tap account, tap Advanced. This will not change the time of already synchronized messages. To solve this, long press the folder(s) in the folder list and select *Delete local messages* and *Synchronize now*.
**(147) What should I know about third party versions?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq147) You likely came here because you are using a third party build of FairEmail. There is **only support** on the latest Play store version, the latest GitHub release and the F-Droid build, but **only if** the version number of the F-Droid build is the same as the version number of the latest GitHub release. F-Droid builds irregularly, which can be problematic when there is an important update. Therefore you are advised to switch to the GitHub release. OAuth access is available only for Play Store and Github releases because email providers permitted the use of OAuth for these releases only. The responsible for a release, for the F-Droid build this is the F-Droid organization, needs to ask for OAuth permissions, which mostly involves signing a contract with binding terms and conditions. Note that you'll need to uninstall the F-Droid build first before you can install a GitHub release because Android refuses to install ("*App was not installed*") the same app with a different signature for security reasons. Note that the GitHub version will automatically check for updates. When desired, this can be turned off in the miscellaneous settings. Please [see here](https://github.com/M66B/FairEmail/blob/master/README.md#user-content-downloads) for all download option and [see here](#user-content-faq173) for the differences between the different release types. If you have a problem with the F-Droid build, please check if there is a newer GitHub version first. You can see the source of the app in *About* of the navigation menu (left side menu), either *Play store*, *GitHub*, *F-Droid*, or *?* (for example in the case of a custom build). [IzzyOnDroid](https://apt.izzysoft.de/fdroid/) hosts the GitHub release of the app. [Aurora Store](https://f-droid.org/packages/com.aurora.store/) hosts the Play store version of the app, even though the Aurora Store app was downloaded from F-Droid.
**(148) How can I use an Apple iCloud account?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq148) There is a built-in profile for Apple iCloud, so you should be able to use the quick setup wizard (other provider). If needed you can find the right settings [here](https://support.apple.com/en-us/HT202304) to manually set up an account. When using two-factor authentication you might need to use an [app-specific password](https://support.apple.com/en-us/HT204397).
**(149) How does the unread message count widget work?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq149) The unread message count widget shows the number of unread messages either for all accounts or for a selected account, but only for the folders for which new message notifications are enabled. Tapping on the notification will synchronize all folders for which synchronization is enabled and will open: * the start screen when all accounts were selected * a folder list when a specific account was selected and when new message notifications are enabled for multiple folders * a list of messages when a specific account was selected and when new message notifications are enabled for one folder
**(150) Can you add cancelling calendar invites?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq150) Cancelling calendar invites (removing calendar events) requires write calendar permission, which will result in effectively granting permission to read and write *all* calendar events of *all* calendars. Given the goal of FairEmail, privacy and security, and given that it is easy to remove a calendar event manually, it is not a good idea to request this permission for just this reason. Inserting new calendar events can be done without permissions with special [intents](https://developer.android.com/guide/topics/providers/calendar-provider.html#intents). Unfortunately, there exists no intent to delete existing calendar events.
**(151) Can you add backup/restore of messages?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq151) An email client is meant to read and write messages, not to backup and restore messages. Note that breaking or losing your device, means losing your messages! Instead, the email provider/server is responsible for backups. If you want to make a backup yourself, you could use a tool like [imapsync](https://imapsync.lamiral.info/). Since version 1.1556 it is possible to export all messages of a POP3 folder in mbox format according to [RFC4155](https://www.ietf.org/rfc/rfc4155.txt), which might be useful to save sent messages if the email server doesn't. If you want to import an mbox file to an existing email account, you can use Thunderbird on a desktop computer and the [ImportExportTools](https://addons.thunderbird.net/nl/thunderbird/addon/importexporttools/) add-on. Note that in case of IMAP all messages on your device are also on the email server.

**(153) Why does permanently deleting Gmail message not work?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq153) You might need to change [the Gmail IMAP settings](https://mail.google.com/mail/u/0/#settings/fwdandpop) on a desktop browser to make it work: * When I mark a message in IMAP as deleted: Auto-Expunge off - Wait for the client to update the server. * When a message is marked as deleted and expunged from the last visible IMAP folder: Immediately delete the message forever Note that archived messages can be deleted only by moving them to the trash folder first. Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view. Another oddity is that a star (favorite message) set via the web interface cannot be removed with the IMAP command ``` STORE -FLAGS (\Flagged) ``` On the other hand, a star set via IMAP is being shown in the web interface and can be removed via IMAP.

If the wizard ends with *AUTHENTICATE failed*, IMAP and/or SMTP might be disabled for the account. In this case you should ask the administrator to enable IMAP and SMTP. The procedure is documented [here](https://docs.microsoft.com/en-in/exchange/troubleshoot/configure-mailboxes/pop3-imap-owa-activesync-office-365). If you've enabled *security defaults* in your organization, you might need to enable the SMTP AUTH protocol.

The following apps are open source cameras and audio recorders: * [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) ([F-Droid](https://f-droid.org/en/packages/net.sourceforge.opencamera/)) * [Audio Recorder version 3.3.24+](https://play.google.com/store/apps/details?id=com.github.axet.audiorecorder) ([F-Droid](https://f-droid.org/packages/com.github.axet.audiorecorder/)) To record voice notes, etc, the audio recorder needs to support [MediaStore.Audio.Media.RECORD_SOUND_ACTION](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media#RECORD_SOUND_ACTION). Oddly, most audio recorders seem not to support this standard Android action.
**(159) What are Disconnect's tracker protection lists?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq159) Please see [here](https://disconnect.me/trackerprotection) for more information about Disconnect's tracker protection lists. For the last updates, please [see here](https://github.com/disconnectme/disconnect-tracking-protection/commits). After downloading the lists in the privacy settings, the lists can optionally be used: * to warn about tracking links on opening links * to recognize tracking images in messages Tracking images will be disabled only if the corresponding main 'disable' option is enabled. Tracking images will not be recognized when the domain is classified as '*Content*', see [here](https://disconnect.me/trackerprotection#trackers-we-dont-block) for more information. This command can be sent to FairEmail from an automation app to update the protection lists: ``` (adb shell) am start-foreground-service -a eu.faircode.email.DISCONNECT.ME ``` Updating once a week will probably be sufficient, please see [here](https://github.com/disconnectme/disconnect-tracking-protection/commits/master) for recent lists changes.
**(160) Can you add permanent deletion of messages without confirmation?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq160) Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-( Please [see here](https://forum.xda-developers.com/t/app-5-0-fairemail-fully-featured-open-source-privacy-oriented-email-app.3824168/post-86984471) for more background information. Since version 1.1601 it is possible to disable confirmation of permanent deletion of individual messages after reading a big warning. Note that the POP3 protocol can download messages from the inbox only. So, deleted messages cannot be uploaded to the inbox again. This means that messages can only be permanently deleted in case of a POP3 account. Advanced: the IMAP delete flag in combination with the EXPUNGE command is not supportable because both email servers and not all people can handle this, risking unexpected loss of messages. A complicating factor is that not all email servers support [UID EXPUNGE](https://tools.ietf.org/html/rfc4315). Since version 1.1485 it is possible to temporarily enable debug mode in the miscellaneous settings to disable auto expunging messages. Note that messages with a *\Deleted* flag will not be shown if auto EXPUNGE is enabled.
**(161) Can you add a setting to change the primary and accent color?*** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq161) If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.
**(162) Is IMAP NOTIFY supported?*** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq162) Yes, [IMAP NOTIFY](https://tools.ietf.org/html/rfc5465) has been supported since version 1.1413. IMAP NOTIFY support means that notifications for added, changed or deleted messages of all *subscribed* folders will be requested and if a notification is received for a subscribed folder, that the folder will be synchronized. Synchronization for subscribed folders can therefore be disable, saving folder connections to the email server. **Important**: push messages (=always sync) for the inbox and subscription management (receive settings) need to be enabled. **Important**: most email servers do not support this! You can check the log via the navigation menu if an email server supports the NOTIFY capability.
**(163) What is message classification?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq163) *This is an experimental feature!* Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc. You can enable message classification in the miscellaneous settings. This will enable 'learning' mode only. The classifier will 'learn' from new messages in the inbox and spam folder by default. The folder property *Classify new messages in this folder* will enable or disable 'learning' mode for a folder. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages. Each folder has an option *Automatically move classified messages to this folder* ('auto classification' for short). When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved. The option *Use local spam filter* in the report spam dialog will turn on message classification in the miscellaneous settings and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in [false positives and false negatives](https://en.wikipedia.org/wiki/False_positives_and_false_negatives). See also [this FAQ](#user-content-faq92). A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the 'marketing' folder, FairEmail will start moving similar messages automatically into this folder. Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text). Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is. To prevent the email server from moving a message into the spam folder again and again, auto classification out of the spam folder will not be done. The message classifier calculates the probability a message belongs in a folder (class). There are two options in the miscellaneous settings which control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder: * *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 15 %) * *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %) If all previously classified messages were the same and the message being evaluated is also the same, the confidence would be 100%. Both conditions must be satisfied before a message will be moved. Considering the default option values: * Apples 40 % and bananas 30 % would be disregarded because the difference of 25 % is below the minimum of 50 % * Apples 10 % and bananas 5 % would be disregarded because the probability for apples is below the minimum of 15 % * Apples 50 % and bananas 20 % would result in selecting apples Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power. This is also why only folders of the same account will be considered. You can delete all classification data by turning classification in the miscellaneous settings three times off. This will be necessary when classification for a folder is enabled or disabled (or when a folder is deleted) because classification is based on comparision. [Filter rules](#user-content-faq71) will be executed before classification. If one or more filter rules were executed for a message, message classification will be skipped because it is assumed that the message will be processed by the filter rules in this case. Message classification is a pro feature, except for the spam folder.
**(164) Can you add customizable themes?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq164) Unfortunately, Android [does not support](https://stackoverflow.com/a/26511725/1794097) dynamic themes, which means all themes need [to be predefined](https://github.com/M66B/FairEmail/blob/master/app/src/main/res/values/styles.xml). Since for each theme there needs to be a light, dark and black variant, it is not feasible to add for each color combination (literally millions) a predefined theme. Moreover, a theme is more than just a few colors. For example themes with a yellow accent color use a darker link color for enough contrast. Most people like the beige background for the light themes, but if you don't like it, it can be disabled in the display settings. The [Material You](https://material.io/blog/announcing-material-you) theme, a more dynamic theme based on the selected background image ("Monet"), which was introduced in Android 12 on Google Pixel devices, is supported and can be selected in the theme selection dialog (via the three-dots menu of the start screen). The theme colors are based on the color circle of [Johannes Itten](https://en.wikipedia.org/wiki/Johannes_Itten). The *Solarized* theme is described in [this article](https://en.wikipedia.org/wiki/Solarized_(color_scheme)).
**(165) Is Android Auto supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq165) Yes, Android Auto is supported, but only with the GitHub version of the app because Google rejected the application of FairEmail for this reason: *App category not permitted - At this time, we are only accepting apps within the Media, short form Messaging, or categories supported by the Android for Cars App Library.* Also, not all Android Auto versions support this (as installed in the car). **Use of this feature with the Github version is expressly at your own risk!** For notification (messaging) support you'll need to enable the following notification options: * *Use Android 'messaging style' notification format* * Notification actions: *Direct reply* and (mark as) *Read* (this might be optional now, but this is untested) You can enable other notification actions too, if you like, but they are not supported by Android Auto. The developers guide is [here](https://developer.android.com/training/cars/messaging).
**(166) Can I snooze a message across multiple devices?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq166) First of all, there is no standard for snoozing messages, so all snooze implementations are custom solutions. Some email providers, like Gmail, move snoozed messages to a special folder. Unfortunately, third party apps have no access to this special folder. Moving a message to another folder and back might fail and might not be possible if there is no internet connection. This is problematic because a message can be snoozed only after moving the message. To prevent these issues, snoozing is done locally on the device by hiding the message while it is snoozing. Unfortunately, it is not possible to hide messages on the email server too. Deleting messages from the server and restoring them later could result in losing messages when the device breaks.
**(167) How can I use DeepL?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq167) DeepL offers free translation of 500,000 characters (~100,000 words; ~250 pages) every month. 1. Make sure you have the latest version of the app installed 1. Check if [DeepL](https://www.deepl.com/) supports your language 1. Enable DeepL support in the miscellaneous settings 1. [Subscribe to](https://www.deepl.com/pro#developer) the DeepL API Free or Pro plan (credit card required; won't be charged) 1. [Copy](https://www.deepl.com/pro-account/plan) the authentication key 1. In the message composer tap on the translate button (文A) in the top action bar, select *Configure* and paste the key This feature requires an internet connection. Note that you can't use [the regular pro plans](https://www.deepl.com/pro). The error *403 forbidden* means that the key and/or plan in invalid. Note that when reading a message, you can use the horizontal three-dots menu to translate too. If you use this frequently, you can configure a button for this.
**(168) What is a spam block list?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq168) A spam block list is basically a list of domain names which have been used to send spam or to spread malware. A spam block list is checked by resolving the server name from the last *Received* header into an IP address and looking up the IP address with a DNS request: ``` Received: ... from smtp.gmail.com ... smtp.gmail.com -> 142.250.27.108 DNS lookup 108.27.250.142.zen.spamhaus.org -> 127.0.0.2: spam NXDOMAIN: not spam ``` NXDOMAIN = no such domain For more information, please see [this article](https://en.wikipedia.org/wiki/Domain_Name_System-based_blackhole_list). You can check common block lists for example [here](https://mxtoolbox.com/blacklists.aspx). FairEmail currently uses the following block lists: * [Spamhaus](https://www.spamhaus.org/) – [Terms of Use](https://www.spamhaus.org/organization/dnsblusage/) — [Privacy policy](https://www.spamhaus.org/organization/privacy/) * [Spamcop](https://www.spamcop.net/) – [Legal info](https://www.spamcop.net/fom-serve/cache/297.html) — [Privacy policy](https://www.spamcop.net/fom-serve/cache/168.html) * [Barracuda](https://www.barracudacentral.org/rbl/how-to-use) – [Request Access](https://www.barracudacentral.org/account/register) – [Privacy policy](https://www.barracuda.com/company/legal/trust-center/data-privacy/privacy-policy) Since version 1.1627 it is possible to enable/disable individual blocklists in the receive settings of the app.
**(169) Why does the app not start automatically?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq169) FairEmail requests Android to start the app when the device starts up. Obviously, this depends on Android as the app cannot start itself. Some Android versions, such as EMUI, have settings to enable or disable auto starting apps. So, if the app isn't started automatically, please check the Android settings. For example for Huawei/EMUI, please [see here](https://dontkillmyapp.com/huawei) for a guide.
**(170) Why can't folders be created with POP3?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq170) The POP3 protocol has commands to download and delete messages from the inbox only. There are no commands to access any other folder. Creating a local folder only and storing messages on your device only is a bad idea because losing or breaking your device would mean losing your messages. Therefore this isn't supportable. Please note that FairEmail doesn't store a copy of your messages in the cloud for privacy reasons. If you want to store messages in folders, please use IMAP, so that there is always a copy of the messages on the email server.
**(171) How can I delete a contact?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq171) A contact can be stored in the Android address book or in the local contact database. When a contact is stored in the Android address book, you can use the Android contacts app to delete the contact. When a contact is store in the local contact database, you can delete it like this: * Go to the settings via the navigation menu (left side menu) * Go to the send settings tab page * Tap on the *Manage* button under *Suggest locally stored contacts* * Locate the contact (you can use the magnifier glass in the top action bar) * Long press the contact and select to delete it
**(172) How can I import contacts?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq172) Like most Android apps, FairEmail consults the Android address book for contact information. There is also a local contact database, which is filled with contacts from sent and received messages. You can enable/disable this in the send settings of the app. If you want to import contacts into the local contact database, this is possible (in recent versions of the app) by tapping on the *Manage* button in the send settings. In the three-dots menu at the top right there is an import (and also an export) [vCard](https://en.wikipedia.org/wiki/VCard)s menu item. The Android address book is managed by the Android Contacts app (or a replacement for this app). Please see [this article](https://support.google.com/contacts/answer/1069522) about importing contacts to the Android address book. Note that some vendors, notably Microsoft, try to lock you into their contact (data) storage. This is not how it should work on Android, which is more open to sharing information.

**(173) What is the difference between Play store / GitHub / F-Droid version?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq173) * The Play store version does not support Android Auto, see [this FAQ](#user-content-faq165) for more information * The Play store version does not support Amazon devices with Android 5 Lollipop because there are critical bugs in this Android version of Amazon * The Play Store version does not support Gravatars/Libravatars due to Play Store policies * The GitHub version will check for [updates on GitHub](https://github.com/M66B/FairEmail/releases) and is updated more frequently, but updates need to be installed manually * The GitHub version has some different links, some more options (like sharing the HTML of a message) and some different default values (more geared to advanced users) * The GitHub version can be installed as an update over the Play store version, whereas the F-Droid build can't (see below for more details) * The F-Droid build does not support OAuth, see [this FAQ](#user-content-faq147) about why not * The F-Droid build does not include [Google Play Billing](https://developer.android.com/google/play/billing/integrate), so Play store purchases cannot be reused * The F-Droid build is supported only if the version number is the same as the version number of the latest GitHub version, see also [this FAQ](#user-content-faq147) The Play store and GitHub version are signed with the [same digital signature](https://github.com/M66B/FairEmail#user-content-downloads) (security certificate). The F-Droid build is signed by the F-Droid organization with a different digital key. This means you can't update the F-Droid build with the Play store or GitHub version or the other way around without reinstalling. However, it is possible to install the GitHub version over the Play store version, and the Play store app will do the same, when auto updating isn't disabled for the app in the app description.
**(174) Is auto discovery supported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq174) Yes, multiple methods of auto discovery are available. The preferred, simplest and fastest method is using DNS records, please see see [RFC6186](https://tools.ietf.org/html/rfc6186) and [RFC8314](https://tools.ietf.org/html/rfc8314) for the details. Example DNS records (SRV=record type, 0=priority, 1=weight, 993/587=port number): ``` _imaps._tcp SRV 0 1 993 imap.example.com. _submission._tcp SRV 0 1 587 smtp.example.com. ``` [Mozilla's autoconfiguration](https://wiki.mozilla.org/Thunderbird:Autoconfiguration) is supported too, but only if the configuration file is accessible via a secure (https) connection. FairEmail will also check the [MX record](https://en.wikipedia.org/wiki/MX_record) and if common email ports (143/993, 465/587) are open. There is no auto discovery for POP3.
**(175) Why should battery optimizations be disabled?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq175) If battery optimizations are enabled ([Doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby)), Android will stop the app when it is running in the background, resulting in no more messages being sent and received in the background anymore. Manufacturers also tweak Android rather often to stop apps in the background for ostensibly better battery life, please [see here](https://dontkillmyapp.com/) for more details.
**(176) When will a message be considered safely transported?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq176) If the receive option *Check transport layer security (TLS)* is enabled, a green shield will be shown only if a message was transported securely by all servers. To show shields, the option *Show authentication status indicator* in the display settings should be enabled. A message will be consired safely transported if *every* [Received](https://datatracker.ietf.org/doc/html/rfc2821#section-4.4) header: * contains the phrase 'using TLS', 'via HTTP', 'version=TLS' * contains the phrase '(qmail invoked by uid )' * contains the phrase '(Postfix, from userid nnn)' * has a *by* with a local address * has a *by* xxx.google.com * has a *from* with a local address * has a *via* with the value '[Frontend Transport](https://social.technet.microsoft.com/wiki/contents/articles/50370.exchange-2016-what-is-the-front-end-transport-service-on-the-mailbox-role.aspx)' * has a *with* with the value 'TLS' * has a *with* with the value 'local', '[LMTPx](https://en.wikipedia.org/wiki/Local_Mail_Transfer_Protocol), '[MAPI](https://en.wikipedia.org/wiki/MAPI)' * has a *with* with the value 'HTTP', 'HTTPS', or 'HTTPREST' * has a *with* with the value '[xMTPSx](https://datatracker.ietf.org/doc/html/rfc3848)' ('xMTPAx' is considered insecure) A local address is a local host address, a site local address or a link local address.

**(177) What does 'Sensitivity' mean?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq177) The sensitivity of a message indicates the confidentiality of a message. * Personal: for you only * Private: for you and trusted people only * Confidential: for a company, organization or department only Please see [this article](https://support.microsoft.com/en-us/office/mark-your-email-as-normal-personal-private-or-confidential-4a76d05b-6c29-4a0d-9096-71784a6b12c1) for more information. The sensitivity indication is sent as [a message header](https://datatracker.ietf.org/doc/html/rfc4021#section-2.1.55).
**(178) Why are widgets not updating?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq178) Apps provide the layout and data for widgets on demand, but the homescreen app/launcher manages all widgets, with a little help from Android. If widgets are not being updated, this is often caused by missing permission. Please see [this video](https://www.youtube.com/watch?v=ywQrYJ6rtnM) about how to fix this.
**(179) What are reply templates?** 🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-faq179) Reply templates are predefined answer texts. They can be defined via the main navigation menu (left side menu). You can reply with a template, insert a template via the three-dots overflow menu in the message editor, and long press on an open space to insert a snippet (the latter requires Android 6 Marshmallow or later). Templates can have the following options: * *Default*: standard template to use when writing a new message * *Use as read receipt*: template to use instead of the default read receipt text * *Favorite*: template will be added in the main reply popup menu * *Snippet*: template will be used as text fragment (since version 1.1857) * *Hide from menus*: template will be hidden (disabled)
**(180) How do I use LanguageTool?** LanguageTool integration needs to be enabled in the miscellaneous settings. After writing some text, you can long press on the save draft button to perform a grammar, style, and spell check via [LanguageTool](https://languagetool.org/). Texts with suggestions will be marked and if you tap on a marked suggestion, it will be shown by the keyboard if the keyboard supports this, else you can double tap or long press the marked text to show suggestions. Since version 1.1974 there is an option to check paragraphs after a new line. The suboption *Use formal form* can be enabled to let LanguageTool suggest more formal text (business, legal, etc).
**(181) How do I use VirusTotal?** VirusTotal integration needs to be enabled in the miscellaneous settings and an API key needs to be entered. To get an API key, you'll need to sign up via the [VirusTotal website](https://www.virustotal.com/). When integration is enabled and an API key is available, a *scan* icon button will be shown for each attachment. Tapping on the scan button will calculate the SHA-256 hash of the attachment and lookup the file via the VirusTotal API. If the file is known by VirusTotal, the number of virus scanners considering the file as malicious will be shown. If the file isn't known by VirusTotal, an upload button will be shown to upload the file for analysis by VirusTotal. This feature was added in version 1.1942 and is available in non Play store versions of the app only.
**(182) How can I select how a link should be opened?** When clicking on a link, a confirmation dialog will be shown. You can select how to open a link below *Open with*. The available browser(s) will be listed and if a browser supports [Custom Tabs](https://developer.chrome.com/docs/android/custom-tabs/), it will be listed twice, once with an "open external" icon (the browser will be started standalone, independent of the app) and once without this icon (the browser will be started embedded as "Custom Tab", dependent of the app). In addition, *Select app* will be listed, which means that the link will be handed over to Android, which will select how to open the link. In most cases, this will be with the default browser, which you can select in the Android settings. If there is choice, Android will ask you how to open the link. You can select *Always* or *Just Once*. If you want to reset *Always*, please [see here](https://support.google.com/pixelphone/answer/6271667) about how to. Note that Android will always use the default browser as selected in the Android settings and therefore will never ask which browser to use. If you ticked *Do not ask this again for [domain name]*, you can undo this by using the *Reset questions* button in the miscellaneous settings tab page of the app. If you disabled confirming links, you can enable this (temporarily) again in the privacy settings tab page of the app (*Confirm opening links*: off). Note that you might need to enable confirming links and reset questions to show the link confirmation dialog again. Please see [this FAQ](#user-content-faq35) on why you should be careful when opening links.
**(183) How do I use Send?** [Send](https://github.com/timvisee/send) is designed as temporary end-to-end encrypted file storage. Only people with a link to a file can download and decrypt a file. See for some more information [Wikipedia](https://en.wikipedia.org/wiki/Firefox_Send). Send integration needs to be enabled in the miscellaneous settings. Optionally, you can change the host address of the Send server. Please [see here](https://github.com/timvisee/send-instances) for a list of public instances. To upload a file and insert a link, you can use the insert link button in the message editor. Send is only available in non-Play Store versions of the app (since version 1.1947).

Get support

🌎 [Google Translate](https://translate.google.com/translate?sl=en&u=https://github.com/M66B/FairEmail/blob/master/FAQ.md%23user-content-get-support) FairEmail is supported on Android smartphones and tablets and ChromeOS only. Only the latest Play store version and latest GitHub release are supported. The F-Droid build is supported only if the version number is the same as the version number of the latest GitHub release. This also means that downgrading is not supported. There is no support on things that are not directly related to FairEmail. There is no support on building and developing things by yourself. Requested features should: * be useful to most people * not complicate the usage of FairEmail * fit within the philosophy of FairEmail (privacy oriented, security minded) * comply with common standards (IMAP, SMTP, etc) * comply with the [Core app quality guidelines](https://developer.android.com/docs/quality-guidelines/core-app-quality) A feature will be considered useful to most people if more than 0.1% of the users request a feature, which in practice means about 500 people. Features not fulfilling these requirements will likely be rejected. This is also to keep maintenance and support in the long term feasible. Note that there are already more features and options in FairEmail than in any other Android email client.
