Hesablara səlahiyyət vermə

Əksər hallarda, cəld quraşdırma sehrbazı doğru konfiqurasiyanı avtomatik olaraq müəyyənləşdirə biləcək.

Cəld quraşdırma sehrbazı uğursuz olsa, əllə bir hesab (e-poçt almaq üçün) və bir kimlik (e-poçt göndərmək üçün) yaratmalı olacaqsınız. Bunun üçün IMAP və SMTP server ünvanlarına və port nömrələrinə, SSL/TSL və ya STARTTLS istifadə etməyə ehtiyac olub-olmadığına, istifadəçi adınıza (əksər hallarda e-poçt ünvanınız, ancaq həmişə yox) və şifrənizə ehtiyac olacaq.

IMAP və təchizatçının adını axtarmaq düzgün sənədləri tapmaq üçün adətən kifayət edir.

Bəzi hallarda hesabınıza xarici girişi təmin etməli və / və ya xüsusi (tətbiqetmə) parol istifadə etməlisiniz, məsələn, iki faktorlu identifikasiya effektiv olduqda.

Tez-tez soruşulan suallar

I have another question.

(1) Which permissions are needed and why?

The following Android permissions are needed:

  • have full network access (INTERNET): to send and receive email
  • view network connections (ACCESS_NETWORK_STATE): to monitor internet connectivity changes
  • run at startup (RECEIVE_BOOT_COMPLETED): to start monitoring on device start
  • foreground service (FOREGROUND_SERVICE): to run a foreground service on Android 9 Pie and later, see also the next question
  • prevent device from sleeping (WAKE_LOCK): to keep the device awake while synchronizing messages
  • in-app billing (BILLING): to allow in-app purchases
  • schedule exact alarm (SCHEDULE_EXACT_ALARM): to use exact alarm scheduling (Android 12 and later)
  • Optional: read your contacts (READ_CONTACTS): to auto complete addresses, to show contact photos and to pick contacts
  • Optional: read the contents of your SD card (READ_EXTERNAL_STORAGE): to accept files from other, outdated apps, see also this FAQ
  • Optional: use fingerprint hardware (USE_FINGERPRINT) and use biometric hardware (USE_BIOMETRIC): to use biometric authentication
  • Optional: find accounts on the device (GET_ACCOUNTS): to select an account when using the Gmail quick setup
  • Android 5.1 Lollipop and before: use accounts on the device (USE_CREDENTIALS): to select an account when using the Gmail quick setup (not requested on later Android versions)
  • Android 5.1 Lollipop and before: Read profile (READ_PROFILE): to read your name when using the Gmail quick setup (not requested on later Android versions)

Optional permissions are supported on Android 6 Marshmallow and later only. On earlier Android versions you will be asked to grant the optional permissions on installing FairEmail.

The following permissions are needed to show the count of unread messages as a badge (see also this FAQ):

  • com.sec.android.provider.badge.permission.READ
  • com.sec.android.provider.badge.permission.WRITE
  • com.htc.launcher.permission.READ_SETTINGS
  • com.htc.launcher.permission.UPDATE_SHORTCUT
  • com.sonyericsson.home.permission.BROADCAST_BADGE
  • com.sonymobile.home.permission.PROVIDER_INSERT_BADGE
  • com.anddoes.launcher.permission.UPDATE_COUNT
  • com.majeur.launcher.permission.UPDATE_BADGE
  • com.huawei.android.launcher.permission.CHANGE_BADGE
  • com.huawei.android.launcher.permission.READ_SETTINGS
  • com.huawei.android.launcher.permission.WRITE_SETTINGS
  • android.permission.READ_APP_BADGE
  • com.oppo.launcher.permission.READ_SETTINGS
  • com.oppo.launcher.permission.WRITE_SETTINGS
  • me.everything.badger.permission.BADGE_COUNT_READ
  • me.everything.badger.permission.BADGE_COUNT_WRITE

FairEmail will keep a list of addresses you receive messages from and send messages to and will use this list for contact suggestions when no contacts permissions is granted to FairEmail. This means you can use FairEmail without the Android contacts provider (address book). Note that you can still pick contacts without granting contacts permissions to FairEmail, only suggesting contacts won't work without contacts permissions.


(2) Why is there a permanent notification shown?

A low priority permanent status bar notification with the number of accounts being monitored and the number of operations pending (see the next question) is shown to prevent Android from killing the service that takes care of continuous receiving email. This was already necessary, but with the introduction of doze mode in Android 6 Marshmallow this is more than ever necessary. Doze mode will stop all apps when the screen is off for some time, unless the app did start a foreground service, which requires showing a status bar notification.

Most, if not all, other email apps don't show a notification with the "side effect" that new messages are often not or late being reported and that messages are not or late being sent.

Android shows icons of high priority status bar notifications first and will hide the icon of FairEmail's notification if there is no space to show icons anymore. In practice this means that the status bar notification doesn't take space in the status bar, unless there is space available.

The status bar notification can be disabled via the notification settings of FairEmail:

  • Android 8 Oreo and later: tap the Receive channel button and disable the channel via the Android settings (this won't disable new message notifications)
  • Android 7 Nougat and before: enabled Use background service to synchronize messages, but be sure to read the remark below the setting

You can switch to periodically synchronization of messages in the receive settings to remove the notification, but be aware that this might use more battery power. See here for more details about battery usage.

Android 8 Oreo might also show a status bar notification with the text Apps are running in the background. Please see here about how you can disable this notification.

Some people suggested to use Firebase Cloud Messaging (FCM) instead of an Android service with a status bar notification, but this would require email providers to send FCM messages or a central server where all messages are collected sending FCM messages. The first is not going to happen and the last would have significant privacy implications.

If you came here by clicking on the notification, you should know that the next click will open the unified inbox.


(3) What are operations and why are they pending?

The low priority status bar notification shows the number of pending operations, which can be:

  • add: add message to remote folder
  • move: move message to another remote folder
  • copy: copy message to another remote folder
  • fetch: fetch changed (pushed) message
  • delete: delete message from remote folder
  • seen: mark message as read/unread in remote folder
  • answered: mark message as answered in remote folder
  • flag: add/remove star in remote folder
  • keyword: add/remove IMAP flag in remote folder
  • label: set/reset Gmail label in remote folder
  • headers: download message headers
  • raw: download raw message
  • body: download message text
  • attachment: download attachment
  • sync: synchronize local and remote messages
  • subscribe: subscribe to remote folder
  • purge: delete all messages from remote folder
  • send: send message
  • exists: check if message exists
  • rule: execute rule on body text
  • expunge: permanently delete messages

Operations are processed only when there is a connection to the email server or when manually synchronizing. See also this FAQ.


(4) How can I use an invalid security certificate / empty password / plain text connection?

... Untrusted ... not in certificate ...


... Invalid security certificate (Can't verify identity of server) ...

This can be caused by using an incorrect host name, so first double check the host name in the advanced identity/account settings (tap Manual setup). Please see the documentation of the email provider about the right host name.

You should try to fix this by contacting your provider or by getting a valid security certificate because invalid security certificates are insecure and allow man-in-the-middle attacks. If money is an obstacle, you can get free security certificates from Let’s Encrypt.

The quick, but unsafe solution (not advised), is to enable Insecure connections in the advanced identity settings (navigation menu, tap Settings, tap Manual setup, tap Identities, tap the identity, tap Advanced).

Alternatively, you can accept the fingerprint of invalid server certificates like this:

  1. Make sure you are using a trusted internet connection (no public Wi-Fi networks, etc)
  2. Go to the setup screen via the navigation menu (swipe from the left side inwards)
  3. Tap Manual setup, tap Accounts/Identities and tap the faulty account and identity
  4. Check/save the account and identity
  5. Tick the checkbox below the error message and save again

This will "pin" the server certificate to prevent man-in-the-middle attacks.

Note that older Android versions might not recognize newer certification authorities like Let’s Encrypt causing connections to be considered insecure, see also here.


Trust anchor for certification path not found

... java.security.cert.CertPathValidatorException: Trust anchor for certification path not found ... means that the default Android trust manager was not able to verify the server certificate chain.

This could be due to the root certificate not being installed on your device or because intermediate certificates are missing, for example because the email server didn't send them.

You can fix the first problem by downloading and installing the root certificate from the website of the provider of the certificate.

The second problem should be fixed by changing the server configuration or by importing the intermediate certificates on your device.

You can pin the certificate too, see above.


Empty password

Your username is likely easily guessed, so this is pretty insecure, unless the SMTP server is available via a restricted local network or a VPN only.

Plain text connection

Your username and password and all messages will be sent and received unencrypted, which is very insecure because a man-in-the-middle attack is very simple on an unencrypted connection.

If you still want to use an invalid security certificate, an empty password or a plain text connection you'll need to enable insecure connections in the account and/or identity settings. STARTTLS should be selected for plain text connections. If you enable insecure connections, you should connect via private, trusted networks only and never via public networks, like offered in hotels, airports, etc.


(5) How can I customize the message view?

In the three dot overflow menu you can enable or disable or select:

  • text size: for three different font sizes
  • compact view: for more condensed message items and a smaller message text font

In the display section of the settings you can enable or disable for example:

  • Unified inbox: to disable the unified inbox and to list the folders selected for the unified inbox instead
  • Tabular style: to show a linear list instead of cards
  • Group by date: show date header above messages with the same date
  • Conversation threading: to disable conversation threading and to show individual messages instead
  • Conversation action bar: to disable the bottom navigation bar
  • Highlight color: to select a color for the sender of unread messages
  • Show contact photos: to hide contact photos
  • Show names and email addresses: to show names or to show names and email addresses
  • Show subject italic: to show the message subject as normal text
  • Show stars: to hide stars (favorites)
  • Show message preview: to show 1-4 lines of the message text
  • Show address details by default: to expand the addresses section by default
  • Automatically show original message for known contacts: to automatically show original messages for contacts on your device, please read this FAQ
  • Automatically show images for known contacts: to automatically show images for contacts on your device, please read this FAQ

Note that messages can be previewed only when the message text was downloaded. Larger message texts are not downloaded by default on metered (generally mobile) networks. You can change this in the connection settings.

Some people ask:

  • to show the subject bold, but bold is already being used to highlight unread messages
  • to move the star to the left, but it is much easier to operate the star on the right side

(6) How can I login to Gmail / G suite?

If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.

If you don't want to use or can't use an on-device Google account, for example on recent Huawei devices, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to set up an account and identity via the manual setup instead of via the quick setup wizard.

Important: sometimes Google issues this alert:

[ALERT] Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)

This Google security check is triggered more often with less secure apps enabled, less with an app password, and hardly when using an on-device account (OAuth).

Please see this FAQ on why only on-device accounts can be used.

Note that an app specific password is required when two factor authentication is enabled.


App specific password

See here about how to generate an app specific password.


Enable "Less secure apps"

Important: using this method is not recommended because it is less reliable.

Important: Gsuite accounts authorized with a username/password will stop working in the near future.

See here about how to enable "less secure apps" or go directy to the setting.

If you use multiple Gmail accounts, make sure you change the "less secure apps" setting of the right account(s).

Be aware that you need to leave the "less secure apps" settings screen by using the back arrow to apply the setting.

If you use this method, you should use a strong password for your Gmail account, which is a good idea anyway. Note that using the standard IMAP protocol in itself is not less secure.

When "less secure apps" is not enabled, you'll get the error Authentication failed - invalid credentials for accounts (IMAP) and Username and Password not accepted for identities (SMTP).


General

You might get the alert "Please log in via your web browser". This happens when Google considers the network that connects you to the internet (this could be a VPN) to be unsafe. This can be prevented by using the Gmail quick setup wizard or an app specific password.

See here for Google's instructions and here for troubleshooting.


(7) Why are sent messages not appearing (directly) in the sent folder?

Sent messages are normally moved from the outbox to the sent folder as soon as your provider adds sent messages to the sent folder. This requires a sent folder to be selected in the account settings and the sent folder to be set to synchronizing.

Some providers do not keep track of sent messages or the used SMTP server might not be related to the provider. In these cases FairEmail, will automatically add sent messages to the sent folder on synchronizing the sent folder, which will happen after a message have been sent. Note that this will result in extra internet traffic.

If this doesn't happen, your provider might not keep track of sent messages or you might be using an SMTP server not related to the provider. In these cases you can enable the advanced identity setting Store sent messages to let FairEmail add sent messages to the sent folder right after sending a message. Note that enabling this setting might result in duplicate messages if your provider adds sent messages to the sent folder too. Also beware that enabling this setting will result in extra data usage, especially when when sending messages with large attachments.

If sent messages in the outbox are not found in the sent folder on a full synchronize, they will be moved from the outbox to the sent folder too. A full synchronize happens when reconnecting to the server or when synchronizing periodically or manually. You'll likely want to enable the advanced setting Store sent messages instead to move messages to the sent folder sooner.


(8) Can I use a Microsoft Exchange account?

The Microsoft Exchange Web Services protocol is being phased out. So, it makes little sense to add this protocol anymore.

You can use a Microsoft Exchange account if it is accessible via IMAP, which is mostly the case. See here for more information.

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.

Please see here for the Microsoft documentation about configuring an email client. There is also a section about common connection errors and solutions.

Some older Exchange server versions have a bug causing empty message and corrupt attachments. Please see this FAQ for a workaround.

Please see this FAQ about ActiveSync support.

Please see this FAQ about OAuth support.


(9) What are identities / how do I add an alias?

Identities represent email addresses you are sending from via an email (SMTP) server.

Some providers allow you to have multiple aliases. You can configure these by setting the email address field of an additional identity to the alias address and setting the user name field to your main email address.

Note that you can copy an identity by long pressing it.

Alternatively, you can enable Allow editing sender address in the advanced settings of an existing identity to edit the username when composing a new message, if your provider allows this.

FairEmail will automatically update the passwords of related identities when you update the password of the associated account or a related identity.

See this FAQ on editing the username of email addresses.


(10) What does 'UIDPLUS not supported' mean?

The error message UIDPLUS not supported means that your email provider does not provide the IMAP UIDPLUS extension. This IMAP extension is required to implement two way synchronization, which is not an optional feature. So, unless your provider can enable this extension, you cannot use FairEmail for this provider.


(11) Why is POP not supported?

Besides that any decent email provider supports IMAP these days, using POP will result in unnecessary extra battery usage and delayed new message notifications. Moreover, POP is unsuitable for two way synchronization and more often than not people read and write messages on different devices these days.

Basically, POP supports only downloading and deleting messages from the inbox. So, common operations like setting message attributes (read, starred, answered, etc), adding (backing up) and moving messages is not possible.

See also what Google writes about it.

For example Gmail can import messages from another POP account, which can be used as a workaround for when your provider doesn't support IMAP.

tl;dr; consider to switch to IMAP.


(12) How does encryption/decryption work?

Communication with email servers is always encrypted, unless you explicitly turned this off. This question is about optional end-to-end encryption with PGP or S/MIME. The sender and recipient should first agree on this and exchange signed messages to transfer their public key to be able to send encrypted messages.


General

Please see here about how public/private key encryption works.

Encryption in short:

  • Outgoing messages are encrypted with the public key of the recipient
  • Incoming messages are decrypted with the private key of the recipient

Signing in short:

  • Outgoing messages are signed with the private key of the sender
  • Incoming messages are verified with the public key of the sender

To sign/encrypt a message, just select the appropriate method in the send dialog. You can always open the send dialog using the three-dots overflow menu in case you selected Don't show again before.

To verify a signature or to decrypt a received message, open the message and just tap the gesture or padlock icon just below the message action bar.

The first time you send a signed/encrypted message you might be asked for a sign key. FairEmail will automatically store the selected sign key in the used identity for the next time. If you need to reset the sign key, just save the identity or long press the identity in the list of identities and select Reset sign key. The selected sign key is visible in the list of identities. If need to select a key on a case by case basis, you can create multiple identities for the same account with the same email address.

In the encryption settings you can select the default encryption method (PGP or S/MIME), enable Sign by default, Encrypt by default and Automatically decrypt messages, but be aware that automatic decryption is not possible if user interaction is required, like selecting a key or reading a security token.

The to be encrypted message text/attachments and the decrypted message text/attachments are stored locally only and will never be added to the remote server. If you want to undo decryption, you can use the resync menu item in the three-dots menu of the message action bar.


PGP

You'll need to install and configure OpenKeychain first. FairEmail was tested with OpenKeychain version 5.4. Later versions will most likely be compatible, but earlier versions might not be.

Important: the OpenKeychain app is known to (silently) crash when the calling app (FairEmail) is not authorized yet and is getting an existing public key. You can workaround this by trying to send a signed/encrypted message to a sender with an unknown public key.

Important: if the OpenKeychain app cannot find a key (anymore), you might need to reset a previously selected key. This can be done by long pressing an identity in the list of identities (Settings, tap Manual setup, tap Identities).

Important: to let apps like FairEmail reliably connect to the OpenKeychain service to encrypt/decrypt messages, it might be necessary to disable battery optimizations for the OpenKeychain app.

Important: the OpenKeychain app reportedly needs contacts permission to work correctly.

Important: on some Android versions / devices it is necessary to enable Show popups while running in background in the additional permissions of the Android app settings of the OpenKeychain app. Without this permission the draft will be saved, but the OpenKeychain popup to confirm/select might not appear.

FairEmail will send the Autocrypt header for use by other email clients, but only for signed and encrypted messages because too many email servers have problems with the often long Autocrypt header. Note that the most secure way to start an encrypted email exchange is by sending signed messages first. Received Autocrypt headers will be sent to the OpenKeychain app for storage on verifying a signature or decrypting a message.

Although this shouldn't be necessary for most email clients, you can attach your public key to a message and if you use .key as extension, the mime type will correctly be application/pgp-keys.

All key handling is delegated to the OpenKey chain app for security reasons. This also means that FairEmail does not store PGP keys.

Inline encrypted PGP in received messages is supported, but inline PGP signatures and inline PGP in outgoing messages is not supported, see here about why not.

Signed-only or encrypted-only messages are not a good idea, please see here about why not:

Signed-only messages are supported, encrypted-only messages are not supported.

Common errors:

  • No key: there is no PGP key available for one of the listed email addresses
  • Missing key for encryption: there is probably a key selected in FairEmail that does not exist in the OpenKeychain app anymore. Resetting the key (see above) will probably fix this problem.
  • Key for signature verification is missing: the public key for the sender is not available in the OpenKeychain app. This can also be caused by Autocrypt being disabled in the encryption settings or by the Autocrypt header not being sent.

S/MIME

Encrypting a message requires the public key(s) of the recipient(s). Signing a message requires your private key.

Private keys are stored by Android and can be imported via the Android advanced security settings. There is a shortcut (button) for this in the encryption settings. Android will ask you to set a PIN, pattern, or password if you didn't before. If you have a Nokia device with Android 9, please read this first.

Note that certificates can contains multiple keys for multiple purposes, for example for authentication, encryption and signing. Android only imports the first key, so to import all the keys, the certificate must first be split. This is not very trivial and you are advised to ask the certificate supplier for support.

Note that S/MIME signing with other algorithms than RSA is supported, but be aware that other email clients might not support this. S/MIME encryption is possible with asymmetric algorithms only, which means in practice using RSA.

The default encryption method is PGP, but the last used encryption method will be remembered for the selected identity for the next time. You can long press on the send button to change the encryption method for an identity. If you use both PGP and S/MIME encryption for the same email address, it might be useful to copy the identity, so you can change the encryption method by selecting one of the two identities. You can long press an identity in the list of identities (via manual setup in the main setup screen) to copy an identity.

To allow different private keys for the same email address, FairEmail will always let you select a key when there are multiple identities with the same email address for the same account.

Public keys are stored by FairEmail and can be imported when verifying a signature for the first time or via the encryption settings (PEM or DER format).

FairEmail verifies both the signature and the complete certificate chain.

Common errors:

  • No certificate found matching targetContraints: this likely means you are using an old version of FairEmail
  • unable to find valid certification path to requested target: basically this means one or more intermediate or root certificates were not found
  • Private key does not match any encryption keys: the selected key cannot be used to decrypt the message, probably because it is the incorrect key
  • No private key: no certificate was selected or no certificate was available in the Android keystore

In case the certificate chain is incorrect, you can tap on the little info button to show the all certificates. After the certificate details the issuer or "selfSign" is shown. A certificate is self signed when the subject and the issuer are the same. Certificates from a certificate authority (CA) are marked with "keyCertSign". Certificates found in the Android key store are marked with "Android".

A valid chain looks like this:

Your certificate > zero or more intermediate certificates > CA (root) certificate marked with "Android"

Note that a certificate chain will always be invalid when no anchor certificate can be found in the Android key store, which is fundamental to S/MIME certificate validation.

Please see here how you can import certificates into the Android key store.

The use of expired keys, inline encrypted/signed messages and hardware security tokens is not supported.

If you are looking for a free (test) S/MIME certificate, see here for the options. Please be sure to read this first if you want to request an S/MIME Actalis certificate. If you are looking for a cheap S/MIME certificate, I had a good experience with Certum.

How to extract a public key from a S/MIME certificate:

openssl pkcs12 -in filename.pfx/p12 -clcerts -nokeys -out cert.pem

You can decode S/MIME signatures, etc, here.


pretty Easy privacy

There is still no approved standard for pretty Easy privacy (p≡p) and not many people are using it.

However, FairEmail can send and receive PGP encrypted messages, which are compatible with p≡p. Also, FairEmail understands incoming p≡p messages since version 1.1519, so the encrypted subject will be shown and the embedded message text will be shown more nicely.


S/MIME sign/encrypt is a pro feature, but all other PGP and S/MIME operations are free to use.


(13) How does search on device/server work?

You can start searching for messages on sender (from), recipient (to, cc, bcc), subject, keywords or message text by using the magnify glass in the action bar of a folder. You can also search from any app by selecting Search email in the copy/paste popup menu.

Searching in the unified inbox will search in all folders of all accounts, searching in the folder list will search in the associated account only and searching in a folder will search in that folder only.

Messages will be searched for on the device first. There will be an action button with a search again icon at the bottom to continue searching on the server. You can select in which folder to continue the search.

The IMAP protocol doesn't support searching in more than one folder at the same time. Searching on the server is an expensive operation, therefore it is not possible to select multiple folders.

Searching local messages is case insensitive and on partial text. The message text of local messages will not be searched if the message text was not downloaded yet. Searching on the server might be case sensitive or case insensitive and might be on partial text or whole words, depending on the provider.

Some servers cannot handle searching in the message text when there are a large number of messages. For this case there is an option to disable searching in the message text.

It is possible to use Gmail search operators by prefixing a search command with raw:. If you configured just one Gmail account, you can start a raw search directly on the server by searching from the unified inbox. If you configured multiple Gmail accounts, you'll first need to navigate to the folder list or the archive (all messages) folder of the Gmail account you want to search in. Please see here for the possible search operators. For example:

raw:larger:10M

Searching through a large number of messages on the device is not very fast because of two limitations:

  • sqlite, the database engine of Android has a record size limit, preventing message texts from being stored in the database
  • Android apps get only limited memory to work with, even if the device has plenty memory available

This means that searching for a message text requires that files containing the message texts need to be opened one by one to check if the searched text is contained in the file, which is a relatively expensive process.

In the miscellaneous settings you can enable Build search index to significantly increase the speed of searching on the device, but be aware that this will increase battery and storage space usage. The search index is based on words, so searching for partial text is not possible. Searching using the search index is by default AND, so searching for apple orange will search for apple AND orange. Words separated by commas result in searching for OR, so for example apple, orange will search for apple OR orange. Both can be combined, so searching for apple, orange banana will search for apple OR (orange AND banana). Using the search index is a pro feature.

From version 1.1315 it is possible to use search expressions like this:

apple +banana -cherry ?nuts

This will result in searching like this:

("apple" AND "banana" AND NOT "cherry") OR "nuts"

Search expressions can be used for searching on the device via the search index and for searching on the email server, but not for searching on the device without search index for performance reasons.

Searching on the device is a free feature, using the search index and searching on the server is a pro feature.


(14) How can I set up an Outlook / Live / Hotmail account?

An Outlook / Live / Hotmail account can be set up via the quick setup wizard and selecting Outlook.

To use an Outlook, Live or Hotmail account with two factor authentication enabled, you need to create an app password. See here for the details.

See here for Microsoft's instructions.

For setting up an Office 365 account, please see this FAQ.


(15) Why does the message text keep loading?

The message header and message body are fetched separately from the server. The message text of larger messages is not being pre-fetched on metered connections and will be fetched on demand on expanding a message. The message text will keep loading if there is no connection to the account, see also the next question, or if there other operations, like synchronizing messages, are being executed.

You can check the account and folder list for the account and folder state (see the legend for the meaning of the icons) and the operation list accessible via the main navigation menu for pending operations (see this FAQ for the meaning of the operations).

If FairEmail is holding off because of prior connectivity issues, please see this FAQ, you can force synchronization via the three dots menu.

In the receive settings you can set the maximum size for automatically downloading of messages on metered connections.

Mobile connections are almost always metered and some (paid) Wi-Fi hotspots are too.


(16) Why are messages not being synchronized?

Possible causes of messages not being synchronized (sent or received) are:

  • The account or folder(s) are not set to synchronize
  • The number of days to synchronize message for is set too low
  • There is no usable internet connection
  • The email server is temporarily not available
  • Android stopped the synchronization service

So, check your account and folder settings and check if the accounts/folders are connected (see the legend in the navigation menu for the meaning of the icons).

If there are any error messages, please see this FAQ.

On some devices, where there are lots of applications competing for memory, Android may stop the synchronization service as a last resort.

Some Android versions stop apps and services too aggressively. See this dedicated website and this Android issue for more information.

Disabling battery optimizations (setup step 3) reduces the chance Android will stop the synchronization service.

In case of successive connection errors, FairEmail will hold off increasingly longer to not drain the battery of your device. This is described in this FAQ.


(17) Why does manual synchronize not work?

If the Synchronize now menu is dimmed, there is no connection to the account.

See the previous question for more information.


(18) Why is the message preview not always shown?

The preview of the message text cannot be shown if the message body has not been downloaded yet. See also this FAQ.


(19) Why are the pro features so expensive?

First of all, FairEmail is basically free to use and only some advanced features need to be purchased.

Zuerst, FairEmail ist grundsätzlich kostenlos und nur einige erweiterte Funktionen müssen gekauft werden.

Tout d'abord, FairEmail est au fond gratuit et seulement quelques fonctionnalités avancées doivent être achetés.

Please see the Play store description of the app or see here for a complete list of pro features.

The right question is "why are there so many taxes and fees?":

  • VAT: 25 % (depending on your country)
  • Google fee: 30 %
  • Income tax: 50 %
  • Paypal fee: 5-10 % depending on the country/amount

So, what is left for the developer is just a fraction of what you pay.

Also note that most free apps will appear not to be sustainable in the end, whereas FairEmail is properly maintained and supported, and that free apps may have a catch, like sending privacy sensitive information to the internet. There are no privacy violating ads in the app either.

I have been working on FairEmail almost every day for more than two years, so I think the price is more than reasonable. For this reason there won't be discounts either.


(20) Can I get a refund?

If a purchased pro feature doesn't work as intended and this isn't caused by a problem in the free features and I cannot fix the problem in a timely manner, you can get a refund. In all other cases there is no refund possible. In no circumstances there is a refund possible for any problem related to the free features, since there wasn't paid anything for them and because they can be evaluated without any limitation. I take my responsibility as seller to deliver what has been promised and I expect that you take responsibility for informing yourself of what you are buying.

(21) How do I enable the notification light?

Before Android 8 Oreo: there is an advanced option in the notification settings of the app for this.

Android 8 Oreo and later: please see here about how to configure notification channels. You can use the button Default channel in the notification settings of the app to directly go to the right Android notification channel settings.

Note that apps cannot change notification settings, including the notification light setting, on Android 8 Oreo and later anymore.

Sometimes it is necessary to disable the setting Show message preview in notifications or to enable the settings Show notifications with a preview text only to workaround bugs in Android. This might apply to notification sounds and vibrations too.

Setting a light color before Android 8 is not supported and on Android 8 and later not possible.


(22) What does account/folder error ... mean?

FairEmail does not hide errors like similar apps often do, so it is easier to diagnose problems.

FairEmail will automatically try to connect again after a delay. This delay will be doubled after each failed attempt to prevent draining the battery and to prevent from being locked out permanently. Please see this FAQ for more information about this.

There are general errors and errors specific to Gmail accounts (see below).

General errors

The error ... Authentication failed ... or ... AUTHENTICATE failed ... likely means that your username or password was incorrect. Some providers expect as username just username and others your full email address username@example.com. When copying/pasting to enter a username or password, invisible characters might be copied, which could cause this problem as well. Some password managers are known to do this incorrectly too. The username might be case sensitive, so try lowercase characters only. The password is almost always case sensitive. Some providers require using an app password instead of the account password, so please check the documentation of the provider. Sometimes it is necessary to enable external access (IMAP/SMTP) on the website of the provider first. Other possible causes are that the account is blocked or that logging in has been administratively restricted in some way, for example by allowing to login from certain networks / IP addresses only.

If needed, you can update a password in the account settings: navigation menu (left side menu), tap Settings, tap Manual setup, tap Accounts and tap on the account. Changing the account password will in most cases automatically change the password of related identities too. If the account was authorized with OAuth via the quick setup wizard instead of with a password, you can run the quick setup wizard again and tick Authorize existing account again to authenticate the account again. Note that this requires a recent version of the app.

The error ... Too many bad auth attempts ... likely means that you are using a Yahoo account password instead of an app password. Please see this FAQ about how to set up a Yahoo account.

The message ... +OK ... likely means that a POP3 port (usually port number 995) is being used for an IMAP account (usually port number 993).

The errors ... invalid greeting ..., ... requires valid address ... and ... Parameter to HELO does not conform to RFC syntax ... can likely be solved by changing the advanced identity setting Use local IP address instead of host name.

The error ... Couldn't connect to host ... means that there was no response from the email server within a reasonable time (20 seconds by default). Mostly this indicates internet connectivity issues, possibly caused by a VPN or by a firewall app. You can try to increase the connection timeout in the connection settings of FairEmail, for when the email server is really slow.

The error ... Connection refused ... means that the email server or something between the email server and the app, like a firewall, actively refused the connection.

The error ... Network unreachable ... means that the email server was not reachable via the current internet connection, for example because internet traffic is restricted to local traffic only.

The error ... Host is unresolved ..., ... Unable to resolve host ... or ... No address associated with hostname ... means that the address of the email server could not be resolved into an IP address. This might be caused by a VPN, ad blocking or an unreachable or not properly working (local) DNS server.

The error ... Software caused connection abort ... means that the email server or something between FairEmail and the email server actively terminated an existing connection. This can for example happen when connectivity was abruptly lost. A typical example is turning on flight mode.

The errors ... BYE Logging out ..., ... Connection reset ... mean that the email server or something between the email server and the app, for example a router or a firewall (app), actively terminated an existing connection.

The error ... Connection closed by peer ... might be caused by a not updated Exchange server, see here for more information.

The errors ... Read error ..., ... Write error ..., ... Read timed out ..., ... Broken pipe ... mean that the email server is not responding anymore or that the internet connection is bad.

The error ... Connection dropped by server? ... means that the email server unexpectedly terminated the connection. This sometimes happen when there were too many connections in a too short time or when a wrong password was used for too many times. In this case, please make sure your password is correct and disable receiving in the receive settings for about 30 minutes and try again. If needed, see this FAQ about how you can reduce the number of connections.

The error ... Unexpected end of zlib input stream ... means that not all data was received, possibly due to a bad or interrupted connection.

The error ... connection failure ... could indicate Too many simultaneous connections.

The warning ... Unsupported encoding ... means that the character set of the message is unknown or not supported. FairEmail will assume ISO-8859-1 (Latin1), which will in most cases result in showing the message correctly.

The error ... Login Rate Limit Hit ... means that there were too many login attempts with an incorrect password. Please double check your password or authenticate the account again with the quick setup wizard (OAuth only).

Please see here for the errors ... Untrusted ... not in certificate ..., ... Invalid security certificate (Can't verify identity of server) ... or ... Trust anchor for certification path not found ...

Please see here for the error ... Syntactically invalid HELO argument(s) ....

Please see here for the error ... Handshake failed ....

See here for what error codes like EHOSTUNREACH and ETIMEDOUT mean.

Possible causes are:

  • A firewall or router is blocking connections to the server
  • The host name or port number is invalid
  • There are problems with the internet connection
  • There are problems with resolving domain names (Yandex: try to disable private DNS in the Android settings)
  • The email server is refusing to accept (external) connections
  • The email server is refusing to accept a message, for example because it is too large or contains unacceptable links
  • There are too many connections to the server, see also the next question

Many public Wi-Fi networks block outgoing email to prevent spam. Sometimes you can workaround this by using another SMTP port. See the documentation of the provider for the usable port numbers.

If you are using a VPN, the VPN provider might block the connection because it is too aggressively trying to prevent spam. Note that Google Fi is using a VPN too.

Send errors

SMTP servers can reject messages for a variety of reasons. Too large messages and triggering the spam filter of an email server are the most common reasons.

  • The attachment size limit for Gmail is 25 MB
  • The attachment size limit for Outlook and Office 365 is 20 MB
  • The attachment size limit for Yahoo is 25 MB
  • 554 5.7.1 Service unavailable; Client host xxx.xxx.xxx.xxx blocked, please see here
  • 501 Syntax error - line too long is often caused by using a long Autocrypt header
  • 503 5.5.0 Recipient already specified mostly means that an address is being used both as TO and CC address
  • 554 5.7.1 ... not permitted to relay means that the email server does not recognize the username/email address. Please double check the host name and username/email address in the identity settings.
  • 550 Spam message rejected because IP is listed by ... means that the email server rejected to send a message from the current (public) network address because it was misused to send spam by (hopefully) somebody else before. Please try to enable flight mode for 10 minutes to acquire a new network address.
  • 550 We're sorry, but we can't send your email. Either the subject matter, a link, or an attachment potentially contains spam, or phishing or malware. means that the email provider considers an outgoing message as harmful.
  • 571 5.7.1 Message contains spam or virus or sender is blocked ... means that the email server considered an outgoing message as spam. This probably means that the spam filters of the email server are too strict. You'll need to contact the email provider for support on this.
  • 451 4.7.0 Temporary server error. Please try again later. PRX4 ...: please see here or see here.
  • 571 5.7.1 Relay access denied: please double check the username and email address in the advanced identity settings (via the manual setup).

If you want to use the Gmail SMTP server to workaround a too strict outgoing spam filter or to improve delivery of messages:

  • Verify your email address here (you'll need to use a desktop browser for this)
  • Change the identity settings like this (Settings, tap Manual setup, tap Identities, tap identity):

  Username: your Gmail address
  Password: an app password
  Host: smtp.gmail.com
  Port: 465
  Encryption: SSL/TLS
  Reply to address: your email address (advanced identity settings)


Gmail errors

The authorization of Gmail accounts setup with the quick wizard needs to be periodically refreshed via the Android account manager. This requires contact/account permissions and internet connectivity.

In case of errors it is possible to authorize/restore a Gmail account again via the Gmail quick setup wizard.

The error ... Authentication failed ... Account not found ... means that a previously authorized Gmail account was removed from the device.

The errors ... Authentication failed ... No token ... means that the Android account manager failed to refresh the authorization of a Gmail account.

The error ... Authentication failed ... network error ... means that the Android account manager was not able to refresh the authorization of a Gmail account due to problems with the internet connection

The error ... Authentication failed ... Invalid credentials ... could be caused by changing the account password or by having revoked the required account/contacts permissions. In case the account password was changed, you'll need to authenticate the Google account in the Android account settings again. In case the permissions were revoked, you can start the Gmail quick setup wizard to grant the required permissions again (you don't need to setup the account again).

The eror ... ServiceDisabled ... might be caused by enrolling in the Advanced Protection Program: "To read your email, you can (must) use Gmail - You won’t be able to use your Google Account with some (all) apps & services that require access to sensitive data like your emails", see here.

When in doubt, you can ask for support.


(23) Why do I get alert ... ?

General

Alerts are warning messages sent by email servers.

Too many simultaneous connections or Maximum number of connections exceeded

This alert will be sent when there are too many folder connections for the same email account at the same time.

Possible causes are:

  • There are multiple email clients connected to the same account
  • The same email client is connected multiple times to the same account
  • Previous connections were terminated abruptly for example by abruptly losing internet connectivity

First try to wait some time to see if the problem resolves itself, else:

  • either switch to periodically checking for messages in the receive settings, which will result in opening folders one at a time
  • or set some folders to poll instead of synchronize (long press folder in the folder list, edit properties)

An easy way to configure periodically checking for messages for all folders except the inbox is to use Apply to all ... in the three-dots menu of the folder list and to tick the bottom two advanced checkboxes.

The maximum number of simultaneous folder connections for Gmail is 15, so you can synchronize at most 15 folders simultaneously on all your devices at the same time. For this reason Gmail user folders are set to poll by default instead of synchronize always. When needed or desired, you can change this by long pressing a folder in the folder list and selecting Edit properties. See here for details.

When using a Dovecot server, you might want to change the setting mail_max_userip_connections.

Note that it will take the email server a while to discover broken connections, for example due to going out of range of a network, which means that effectively only half of the folder connections are available. For Gmail this would be just 7 connections.


(24) What is browse messages on the server?

Browse messages on the server will fetch messages from the email server in real time when you reach the end of the list of synchronized messages, even when the folder is set to not synchronize. You can disable this feature in the advanced account settings.


(25) Why can't I select/open/save an image, attachment or a file?

When a menu item to select/open/save a file is disabled (dimmed) or when you get the message Storage access framework not available, the storage access framework, a standard Android component, is probably not present. This might be because your custom ROM does not include it or because it was actively removed (debloated).

FairEmail does not request storage permissions, so this framework is required to select files and folders. No app, except maybe file managers, targeting Android 4.4 KitKat or later should ask for storage permissions because it would allow access to all files.

The storage access framework is provided by the package com.android.documentsui, which is visible as Files app on some Android versions (notable OxygenOS).

You can enable the storage access framework (again) with this adb command:

pm install -k --user 0 com.android.documentsui

Alternatively, you might be able to enable the Files app again using the Android app settings.


(26) Can I help to translate FairEmail in my own language?

Yes, you can translate the texts of FairEmail in your own language on Crowdin. Registration is free.

If you would like your name or alias to be included in the list of contributors in About the app, please contact me.


(27) How can I distinguish between embedded and external images?

External image:

Xarici təsvir

Embedded image:

Pərçimlənmiş təsvir

Broken image:

Zədəli təsvir

Note that downloading external images from a remote server can be used to record you did see a message, which you likely don't want if the message is spam or malicious.


(28) How can I manage status bar notifications?

In the notification settings you'll find a button Manage notifications to directly navigate to the Android notifications settings for FairEmail.

On Android 8.0 Oreo and later you can manage the properties of the individual notification channels, for example to set a specific notification sound or to show notifications on the lock screen.

FairEmail has the following notification channels:

  • Service: used for the notification of the synchronize service, see also this FAQ
  • Send: used for the notification of the send service
  • Notifications: used for new message notifications
  • Warning: used for warning notifications
  • Error: used for error notifications

See here for details on notification channels. In short: tap on the notification channel name to access the channel settings.

On Android before Android 8 Oreo you can set the notification sound in the settings.

See this FAQ if your device has a notification light.


(29) How can I get new message notifications for other folders?

Just long press a folder, select Edit properties, and enable either Show in unified inbox or Notify new messages (available on Android 7 Nougat and later only) and tap Save.


(30) How can I use the provided quick settings?

There are quick settings (settings tiles) available to:

  • globally enable/disable synchronization
  • show the number of new messages and marking them as seen (not read)

Quick settings require Android 7.0 Nougat or later. The usage of settings tiles is explained here.


(31) How can I use the provided shortcuts?

There are shortcuts available to compose a new message to a favorite contact.

Shortcuts require Android 7.1 Nougat or later. The usage of shortcuts is explained here.

It is also possible to create shortcuts to folders by long pressing a folder in the folder list of an account and selecting Add shortcut.


(32) How can I check if reading email is really safe?

You can use the Email Privacy Tester for this.


(33) Why are edited sender addresses not working?

Most providers accept validated addresses only when sending messages to prevent spam.

For example Google modifies the message headers like this for unverified addresses:

From: Somebody <somebody@example.org>
X-Google-Original-From: Somebody <somebody+extra@example.org>

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?

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 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.

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:

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?

Viewing remotely stored images (see also this FAQ) 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?.

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, 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 ....

If you want to reset the default Open with apps, please see here.


(36) How are settings files encrypted?

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?

All supported Android versions encrypt all user data, 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.


(39) How can I reduce the battery usage of FairEmail?

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

As a rule of thumb the battery usage should be below or in any case not be much higher than Mobile network standby. If this isn't the case, please turn on Auto optimize in the receive settings. If this doesn't help, please ask for support.

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 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 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 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 as IMAP server, you could ask your provider to change the imap_idle_notify_interval 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 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 errors.


(40) How can I reduce the data usage of FairEmail?

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' ?

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.

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 anymore.

The error 'Handshake failed ... UNSUPPORTED_PROTOCOL or TLSV1_ALERT_PROTOCOL_VERSION ...' might be caused by enabling hardening connections in the connection settings or by Android not supporting older protocols anymore, like SSLv3.

Android 8 Oreo and later do not support 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).

You can use this website or this website to check for SSL/TLS problems of email servers.


(42) Can you add a new provider to the list of providers?

If the provider is used by more than a few people, yes, with pleasure.

The following information is needed:

<provider
    name="Gmail"
    link="https://support.google.com/mail/answer/7126229" // link to the instructions of the provider
    type="com.google"> // this is not needed
    <imap
        host="imap.gmail.com"
        port="993"
        starttls="false" />
    <smtp
        host="smtp.gmail.com"
        port="465"
        starttls="false" />
</provider>

The EFF writes: "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 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 ... ?

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, which will attempt to make small text more readable.


(44) Can you show contact photos / identicons in the sent folder?

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!' ?

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?

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.


(47) How do I solve the error 'No primary account or no drafts folder' ?

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 for some more information.


(48) How do I solve the error 'No primary account or no archive folder' ?

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' ?

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 anymore.

See also question 25 and what Google writes about it.


(50) Can you add an option to synchronize all messages?

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?

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?

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 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?

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?

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?

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?

There are almost no providers offering the JMAP protocol, so it is not worth a lot of effort to add support for this to FairEmail.


(57) Can I use HTML in signatures?

Yes, you can use 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, you should wrap the text in a pre element, like this:

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

(58) What does an open/closed email icon mean?

The email icon in the folder list can be open (outlined) or closed (solid):

Xarici təsvir

Message bodies and attachments are not downloaded by default.

Xarici təsvir

Message bodies and attachments are downloaded by default.


(59) Can original messages be opened in the browser?

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 could be used to share these files, but even Google's Chrome cannot handle this.


(60) Did you know ... ?

  • Did you know that starred messages can be synchronized/kept always? (this can be enabled in the receive settings)
  • Did you know that you can long press the 'write message' icon to go to the drafts folder?
  • Did you know there is an advanced option to mark messages read when they are moved? (archiving and trashing is also moving)
  • Did you know that you can select text (or an email address) in any app on recent Android versions and let FairEmail search for it?
  • Did you know that FairEmail has a tablet mode? Rotate your device in landscape mode and conversation threads will be opened in a second column if there is enough screen space.
  • Did you know that you can long press a reply template to create a draft message from the template?
  • Did you know that you can long press, hold and swipe to select a range of messages?
  • Did you know that you can retry sending messages by using pull-down-to-refresh in the outbox?
  • Did you know that you can swipe a conversation left or right to go to the next or previous conversation?
  • Did you know that you can tap on an image to see where it will be downloaded from?
  • Did you know that you can long press the folder icon in the action bar to select an account?
  • Did you know that you can long press the star icon in a conversation thread to set a colored star?
  • Did you know that you can open the navigation drawer by swiping from the left, even when viewing a conversation?
  • Did you know that you can long press the people's icon to show/hide the CC/BCC fields and remember the visibility state for the next time?
  • Did you know that you can insert the email addresses of an Android contact group via the three dots overflow menu?
  • Did you know that if you select text and hit reply, only the selected text will be quoted?
  • Did you know that you can long press the trash icons (both in the message and the bottom action bar) to permanently delete a message or conversation? (version 1.1368+)
  • Did you know that you can long press the send action to show the send dialog, even if it was disabled?
  • Did you know that you can long press the full screen icon to show the original message text only?
  • Did you know that you can long press the answer button to reply to the sender? (since version 1.1562)

(61) Why are some messages shown dimmed?

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 are shown in the operations view accessible from the main navigation menu.


(62) Which authentication methods are supported?

The following authentication methods are supported and used in this order:

  • CRAM-MD5
  • LOGIN
  • PLAIN
  • NTLM (untested)
  • XOAUTH2 (Gmail, Yandex)

SASL authentication methods, besides CRAM-MD5, are not supported because JavaMail for 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 can be selected in the account and identity settings.

Server Name Indication is supported by all supported Android versions.


(63) How are images resized for displaying on screens?

Large inline or attached PNG and JPEG images will automatically be resized for displaying on screens. This is because email messages are limited in size, depending on the provider mostly between 10 and 50 MB. Images will by default be resized to a maximum width and height of about 1440 pixels and saved with a compression ratio of 90 %. Images are scaled down using whole number factors to reduce memory usage and to retain image quality. Automatically resizing of inline and/or attached images and the maximum target image size can be configured in the send settings.

If you want to resize images on a case-by-case basis, you can use Send Reduced or a similar app.


(64) Can you add custom actions for swipe left/right?

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.

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?

Inline (image) attachments are shown dimmed. Inline attachments are supposed to be downloaded and shown automatically, but since FairEmail doesn't always download attachments automatically, see also this FAQ, 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?

"You can't share in-app purchases and free apps with your family members."

See here under "See if content is eligible to be added to Family Library", "Apps & games".


(67) How can I snooze conversations?

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, 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?

Adobe Acrobat reader and Microsoft apps still expects full access to all stored files, while apps should use the Storage Access Framework 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.


(69) Can you add auto scroll up on new message?

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?

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 (from 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?

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.

The following rule conditions are available:

  • Sender contains or sender is contact
  • Recipient contains
  • Subject contains
  • Has attachments (optional of specific type)
  • Header contains
  • 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" <somebody@example.org>

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. Please see here for the documentation of Java regular expressions. You can test a regex here.

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 is enabled to be able to match unfolded headers.

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)
  • Answer/forward (with template)
  • Text-to-speech (sender and subject)
  • Automation (Tasker, etc)

An error in a rule condition can lead to a disaster, therefore irreversible actions are not supported.

Rules are applied directly after the message header has been fetched, but before the message text has been downloaded, so it is not possible to apply conditions to the message text. Note that large message texts are downloaded on demand on a metered connection to save on data usage.

If you want to forward a message, consider to use the move action instead. This will be more reliable than forwarding as well because forwarded messages might be considered as spam.

Since message headers are not downloaded and stored by default to save on battery and data usage and to save storage space it is not possible to preview which messages would match a header rule condition.

Some common header conditions (regex):

  • .*Auto-Submitted:.* RFC3834
  • .*Content-Type: multipart/report.* RFC3462

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.

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?

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.

There can be just one primary account and there can be just one primary identity per account.


(73) Is moving messages across accounts safe/efficient?

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?

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?

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?

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?

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, so there is little room for performance improvements.


(78) How do I use schedules?

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.

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 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.

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 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.

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, 15, 30, 60, 120, 240, 480, 1440. A value of 0 means push messages.

You can automatically send commands with for example Tasker:

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)?

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 too.


(80) How do I fix the error 'Unable to load BODYSTRUCTURE' ?

The error message Unable to load BODYSTRUCTURE is caused by bugs in the email server, see here 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 dark in the dark theme?

The original message is shown as the sender has sent it, including all colors. Changing the background color would not only make the original view not original anymore, it can also result in unreadable messages.


(82) What is a tracking image?

Please see here about what a tracking image exactly is. In short tracking images keep track if you opened a message.

FairEmail will in most cases automatically recognize tracking images and replace them by this icon:

Xarici təsvir

Automatic recognition of tracking images can be disabled in the privacy settings.


(84) What are local contacts for?

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 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?

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'?

The advanced option extra privacy features enables:

  • Looking up the owner of the IP address of a link
  • Detection and removal of tracking images

(87) What does 'invalid credentials' mean?

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.

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.


(88) How can I use a Yahoo, AOL or Sky account?

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, AOL, or Sky account you will need to create an app password. For instructions, please see here:

Please see this FAQ 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 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?

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 messages only, you can enable this in the advanced identity options. You might want to create a new identity for this if you want/need to select sending plain text messages on a case-by-case basis.


(90) Why are some texts linked while not being a link?

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 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?

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 about optimizing battery usage.


(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?

Spam filtering, verification of the DKIM signature and SPF 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.

Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see this FAQ 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 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 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 authentication failed on the receiving server. You can enable/disable authentication verification 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 (from 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 to check authentication and other things.


(93) Can you allow installation/data storage on external storage media (sdcard)?

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.

Messages, attachments, etc stored on external storage media, like an sdcard, can be accessed by other apps and is therefore not safe. See here for the details.

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 for. 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?

The red/orange stripe at the left side of the header means that the DKIM, SPF or DMARC authentication failed. See also this FAQ.


(95) Why are not all apps shown when selecting an attachment or image?

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. 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 and here for more details.


(96) Where can I find the IMAP and SMTP settings?

The IMAP settings are part of the (custom) account settings and the SMTP settings are part of the identity settings.


(97) What is 'cleanup' ?

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?

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?

FairEmail provides common text formatting (bold, italic, underline, text size and color) via a toolbar that appears after selecting some text.

A Rich text or 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 for some more details about this.


(100) How can I synchronize Gmail categories?

You can synchronize Gmail categories by creating filters to label categorized messages:

  • Create a new filter via Gmail > Settings (wheel) > 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

Unfortunately, this is not possible for 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?

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?

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 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 and PNG images can contain Exif information.


(104) What do I need to know about error reporting?

  • Error reports will help improve FairEmail
  • Error reporting is optional and opt-in
  • Error reporting can be enabled/disabled in the settings, section miscellaneous
  • Error reports will automatically be sent anonymously to Bugsnag
  • Bugsnag for Android is open source
  • See here about what data will be sent in case of errors
  • See here for the privacy policy of Bugsnag
  • Error reports will be sent to sessions.bugsnag.com:443 and notify.bugsnag.com:443

(105) How does the roam-like-at-home option work?

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 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?

Please see here for a list of launchers which can show the number of unread messages.

Note that Nova Launcher requires Tesla Unread, which is not supported anymore.

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.

Some launchers display a dot or a '1' for the monitoring notification, 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 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?

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.

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?

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?

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 for the options
  • Use app specific passwords, see this FAQ

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?

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?

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 ($15,000 to $75,000) for this. You can read more about this here.

OAuth for Outlook/Office 365, Yahoo, Mail.ru and Yandex is supported via the quick setup wizard.


(112) Hansı e-poçt təchizatçısını tövsiyə edirsiniz?

FairEmail sadəcə bir e-poçt müştərisidir, ona görə də öz e-poçt ünvanınızı gətirməyiniz lazımdır. Bunun tətbiq açıqlamasında daha dəqiq qeyd edildiyini unutmayın.

Aralarından seçim edə biləcəyiniz çoxlu e-poçt təchizatçısı var. Hansı e-poçt təchizatçısının sizin üçün daha yaxşı olduğu istək/tələblərinizdən asılıdır. Üstünlükləri və çatışmazlıqları olan gizlilik yönümlü e-poçt təchizatçılarının bir siyahısı üçün zəhmət olmasa Gizliliyin bərpası və ya Gizlilik alətləri veb saytlarına baxın.

ProtonMail, Tutanota kimi bəzi təchizatçılar, üçüncü tərəf e-poçt tətbiqlərinin istifadəsini mümkünsüz edən xüsusi e-poçt protokolları istifadə edir. Daha ətraflı məlumat üçün zəhmət olmasa TSS-a baxın.

Əksər e-poçt təchizatçısı tərəfindən dəstəklənən öz (özəl) domen adınızı istifadə etmək, başqa e-poçt təchizatçısına keçməyi də asanlaşdıracaq.


(113) How does biometric authentication work?

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.

Biometric authentication is a pro feature.


(114) Can you add an import for the settings of other email apps?

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?

Email address chips 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.


(116) How can I show images in messages from trusted senders by default?

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) Can you help me restore my purchase?

First of all, a purchase will be available on all devices logged into the same Google account, if the app is installed via the same Google account too. You can select the account in the Play store app.

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
  • 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
  • Make sure the Play store app is up to date, please see here
  • 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
  • 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, which is also not allowed by Play Store rules

If you cannot solve the problem with the purchase, you will have to contact Google about it.


(118) What does 'Remove tracking parameters' exactly?

Checking Remove tracking parameters will remove all UTM parameters from a link.


(119) Can you add colors to the unified inbox widget?

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?

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. 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 about when messages in a conversation will be auto expanded and marked read.


(121) How are messages grouped into a conversation?

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?

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?

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 15, 30 and eventually every 60 minutes and let the device sleep (=no battery usage).

Note that Android doze mode does not allow to wake the device earlier than after 15 minutes.

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'?

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. Belə mesajların yenidən formatlanması və görüntülənməsi çox uzun çəkir. Bunun əvəzinə səyyah tərəfindən təmin edilmiş orijinal mesaj görünüşünü sınaya bilərsiniz.


(125) Hazırkı təcrübi özəlliklər nələrdir?

Mesajın sinifləşdirilməsi (1.1438+ versiya)

Təfsilatlar üçün zəhmət olmasa bu TSS-a baxın.

Bəzi arxaplan üçün, bu Vikipediya məqaləsinə baxın.


(126) Geyinilə bilən cihazlarıma mesaj önbaxışlarını göndərə bilərəm?

FairEmail bir mesajı iki addımda gətirir:

  1. Mesaj başlıqlarını gətirir
  2. Mesaj mətnini və qoşmalarını gətirir

İlk addımdan dərhal sonra yeni mesajlar bildiriləcək. Ancaq, yalnız ikinci addımdan sonra mesaj mətni əlçatan olacaq. FairEmail, mövcud bildirişləri, mesaj mətninin bir önbaxışı ilə yeniləyir, ancaq təəssüf ki, geyinilə bilən cihaz bildirişləri yenilənə bilmir.

Bir mesaj mətninin həmişə bir mesaj başlığından dərhal sonra gətiriləcəyinin zəmanəti olmadığı kimi, bir önbaxış mətni ehtiva edən yeni mesaj bildirişinin geyinilə bilən cihaza həmişə göndəriləcəyinin də zəmanəti yoxdur.

Bunun yetəri qədər yaxşı olduğunu düşünürsünüzsə, Geyinilə bilən cihazlara yalnız mesaj önbaxışı olan bildirişlər göndər bildiriş seçimini fəallaşdıra bilərsiniz, əgər bu işləməsə, Yalnı önbaxış mətni olan bildirişləri göstər bildiriş seçimini fəallaşdırmağa çalışa bilərsiniz. Unutmayın ki, hətta Android Wear tətbiqi, bildirişin göndərildiyini (bridged) desə belə, bu, önbaxış mətnini göstərməyən geyinilə bilən cihazlara da tətbiq olunur.

Geyinilə bilən cihazlara tam mesaj mətninin göndərilməsini istəyirsinizsə, Bütün mətnə önbaxış bildiriş seçimini fəallaşdıra bilərsiniz. Unutmayın, bəzi geyinilə bilən cihazlarda bu özəllik fəallaşdırılanda çökmə baş verir.

Galaxy Wearable (Samsung Gear) tətbiqi ilə bir Samsung geyinilə bilən cihaz istifadə edirsinizsə, Bildirişlər tənzimlənəndə FairEmail üçün bildirişləri fəallaşdırmalısınız, bu tətbiqdə Gələcəkdə quraşdırılan tətbiqlər seçimi sönülü olmalıdır.


(127) "Sintaktik olaraq etibarsız arqument(lər)i"ni necə düzəldə bilərəm?

Sintaktik olaraq etibarsız HELO arqument(lər)i xətası, SMTP serverinin yerli IP ünvanı və ya host adını rədd etdiyi mənasını verir. Böyük ehtimalla bu xətanı abaqcıl kimlik seçimi olan Host adı əvəzinə yerli IP ünvanını istifadə et seçimini fəallaşdıraraq/sıradan çıxardaraq düzəldə bilərsiniz.


(128) Məsələn təsvirləri göstərmək üçün, soruşulan sualları necə sıfırlaya bilərəm?

Qarışıq tənzimləmələrindəki üç-nöqtə daşma menyusu vasitəsilə soruşulan sualları sıfırlaya bilərsiniz.


(129) ProtonMail, Tutanota dəstəklənir?

ProtonMail, xüsusiyyətçi bir e-poçt protokolu istifadə edir və IMAP-ı birbaşa dəstəkləmir, ona görə də ProtonMail-ə müraciət etmək üçün FairEmail-i istifadə edə bilməzsiniz.

Tutanota, xüsusiyyətçi bir e-poçt protokolu istifadə edir və IMAP-ı birbaşa dəstəkləmir, ona görə də Tutanota-ya müraciət etmək üçün FairEmail-i istifadə edə bilməzsiniz.


(130) Mesaj xətasının mənası nədir...?

A series of lines with orangish or red texts with technical information means that debug mode was enabled in the miscellaneous settings.

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 for other error messages in the outbox.


(131) Can you change the direction for swiping to previous/next message?

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.

Bu davranış mənə olduqca normal görünür, çünki səhifələrin çevrilməsinə də oxşayır.

Yenə də, sürüşdürmə istiqamətini tərsinə çevirmək üçün bir davranış tənzimləməsi var.


(132) Yeni mesajların bildirişləri niyə səssizdədir?

Bildirişlər bəzi MIUI versiyalarında ilkin olaraq səssizdədir. Bunun necə düzəldiləcəyinə baxmaq üçün zəhmət olmasa bura baxın.

Bəzi Android versiyalarında setOnlyAlertOnce-ın bildirişləri səssizə almasına səbəb olan bir xəta var. FairEmail, mesaj başlıqlarını aldıqdan dərhal sonra yeni mesaj bildirişlərini göstərir və FairEmail-in, mesaj mətnini aldıqdan sonra yeni mesaj bildirişlərini yeniləməsinə ehtiyac var. Bu, FairEmail tərəfindən düzəldilə və ya həll edilə bilməz.

Android, bildiriş səsinin sürətini məhdudlaşdıra bilər, bu da bəzi yeni mesaj bildirişlərinin səssizdə qalmasına səbəb ola bilər.


(133) Niyə ActiveSync dəstəklənmir?

Microsoft Exchange ActiveSync protokolu patentləşdirilib və buna görə də dəstəklənmir. Buna görə də ActiveSync-i dəstəkləyən başqa bir e-poçt müştərisi tapa bilməzsiniz.

Unutmayın ki, FairEmail-in açıqlaması belə başlayır: Microsoft Exchange Veb Xidmətləri və Microsoft ActiveSync kimi standart olmayan protokollar dəstəklənmir.


(134) Yerli (yaddaşdakı) mesajları silməyi əlavə edə bilərsiniz?

POP3

Hesab tənzimləmələrində (Tənzimləmələr > Əllə quraşdırma > Hesablar > Hesab) Silinən mesajları serverdə burax seçimini fəallaşdıra bilərsiniz.

IMAP

IMAP protokolu iki formada eyniləşdirməyi nəzərdə tutduğu üçün cihazdan bir mesajın silinməsi, təkrar eyniləşdirmə zamanı mesajın yenidən alınmasına səbəb olacaq.

Ancaq FairEmail, mesaj mətninin üzərindəki hərəkət sətrindəki üç-nöqtə menyusu vasitəsilə və ya mesaj siyahısında bir neçə mesajı seçərək mesajların gizlədilməsini dəstəkləyir. Əsasən bu, POP3 protokolunun "serverdə burax" tənzimləməsi ilə eynidir və ehtiyac olanda mesajları yenidən göstərə bilmə üstünlüyünə sahibdir.

Unutmayın ki, bir mesajı gizlətmək üçün sola və ya sağa sürüşdürmə əməliyyatını tənzimləmək mümkündür.


(135) Tullantı və qaralamalar qovluğundakı mesajlar niyə danışıqlarda göstərilir?

Fərdi mesajlar nadir hallarda tullantı qovluğuna atılır və əksər hallarda bu təsadüfən baş verir. Danışıqlarda tullantı qovluğuna atılan mesajların göstərilməsi, onların tapılmasını asanlaşdırır.

Mesajı birdəfəlik silmək üçün üç-nöqtəli sil menyusunu istifadə edə bilərsiniz, bu da, mesajı danışıqdan siləcək. Unutmayın ki, bunun geri dönüşü yoxdur.

Eynilə, qaralamalar, aid olduğu konteksdə tapılması üçün danışıqlarda göstərilir. Qaralamanı daha sonra yazmağa davam etməzdən əvvəl alınan mesajları oxumaq asandır.


(136) Bir hesabı/kimliyi/qovluğu necə silə bilərəm?

İstəmədən və səhvən silmənin qarşısını almaq üçün bir hesabın/kimliyin/qovluğun silinməsi bir az gizlədilmişdir.

  • Hesab: Tənzimləmələr > Əllə quraşdırma > Hesablar > Hesab
  • Kimlik: Tənzimləmələr > Əllə quraşdırma > Kimliklər > Kimlik
  • Qovluq: Qovluq siyahısında qovluğa uzun basın > Xüsusiyyətlərə düzəliş et

Sağ üstdəki üç-nöqtəli daşma menyusunda hesabı/kimliyi/qovluğu silmək üçün bir element var.


(137) "Bir də soruşma"nı necə sıfırlaya bilərəm?

Yenidən soruşmayacaq şəkildə tənzimlənmiş bütün sualları Qarışıq tənzimləmələrində sıfırlaya bilərsiniz.


(138) Təqvim/əlaqə/tapşırıq/qeyd idarəetməsi əlavə edə bilərsiniz?

Təqvim, əlaqə, tapşırıq və qeyd idarəetməsi ayrı, xüsusi bir tətbiqlə daha yaxşı edilə bilər. Unutmayın ki, FairEmail, bir ofis paketi deyil, xüsusi bir e-poçt tətbiqidir.

Həmçinin, bir çox şeyi yarımçıq saxlamaq əvəzinə bir neçə şeyi yaxşı etməyi üstün tuturam. Həmçinin təhlükəsizlik baxımından, bir tətbiqə bir neçə icazə vermək heç də yaxşı bir fikir deyil.

Təqvimlərinizi/əlaqələrinizi eyniləşdirmək/idarə etmək üçün mükəmməl, açıq mənbəli DAVx⁵ tətbiqini istifadə etməyi məsləhət görürəm.

Əksər təchizatçılar əlaqələri ixrac etməyi dəstəkləyir. Əgər eyniləşdirmə mümkün deyilsə, əlaqələri necə idxal edə biləyiniz barəsində zəhmət olmasa bura baxın.

Unutmayın ki, FairEmail təqvim dəvətlərini cavablamağı (pro özəllik) və şəxsi təqviminizə təqvim dəvətlərini əlavə etməyi dəstəkləyir.


(139) "İstifadəçinin kimliyi təsdiqləndi, ancaq bağlantı qurulmadı" problemini necə düzəldə bilərəm?

Əslində bu, "Microsoft Exchange"ə xas olan bir xətadır, köhnə Exchange serverinin proqram təminatındakı bir xətaya görə yaranmış yanlış xəta mesajıdır.

İstifadəçinin kimliyi təsdiqləndi, ancaq bağlantı qurulmadı xətası, bu hallarda yarana bilər:

  • Ani mesajlar çox qovluq üçün fəallaşdırıldı: daha çox məlumat və müvəqqəti həll yolu üçün bu TSS-a baxın
  • Hesab şifrəsi dəyişdirildi: şifrəni FairEmail-də də dəyişdirmək, problemi həll edəcək
  • İstifadəçi adı kimi əsas e-poçt ünvanı əvəzinə ləqəb e-poçt ünvanı istifadə edilir
  • Paylaşılan bir poçt qutusu üçün yanlış giriş sxemi istifadə olunur, doğru sxem belədir: username@domain\SharedMailboxAlias

Paylaşılan poçt qutusu ləqəbi, əksər hallarda paylaşılan hesabın e-poçt ünvanı olacaq, məsələn belə:

siz@nümune.com\paylaşılan@nümune.com

Diqqət edin ki, burada "/" deyil, onun tərsi, yəni "" olmalıdır.

Paylaşılan bir poçt qutusu istifadə edərkən, böyük ehtimalla alma tənzimləmələrində Paylaşılan qovluq siyahılarını eyniləşdir seçimini fəallaşdırmaq istəyəcəksiniz.


(140) Mesaj mətnində niyə qəribə simvollar var?

Qəribə simvolların görüntülənməsi, demək olar ki, həmişə göndərənin proqram təminatı ya heç bir simvolu, ya da etibarsız simvolların kodlaşdırılmasını göstərdiyi üçün baş verir. Heç bir simvol tənzimlənməyəndə ya da, US-ASCII göstəriləndə FairEmail, ISO 8859-1 qəbul edəcək. Bundan başqa doğru simvol kodlaşdırmasını güvənli şəkildə avtomatik müəyyənləşdirməyin heç bir yolu yoxdur, buna görə də, bu, FairEmail tərəfindən düzəldilə bilməz. Doğru əməliyyat, göndərənə şikayət göndərir.


(141) "Mesaj göndərmək üçün bir qaralama qovluğu tələb olunur" problemini necə düzəldə bilərəm?

Qaralama mesajları saxlamaq üçün qaralama qovluğu tələb olunur. Bir çox hallarda FairEmail, e-poçt serverinin göndərdiyi atributlara əsaslanaraq bir hesab əlavə edəndə qaralamalar qovluğunu avtomatik seçəcək. Yenə də, bəzi e-poçt serverləri düzgün konfiqurasiya edilməyib və bu atributları göndərmir. Bu halda FairEmail, qaralamalar qovluğunu ada görə müəyyənləşdirməyə çalışır, əgər qaralamalar qovluğunun qeyri-adi bir adı varsa və ya ümumiyyətlə heç yoxdursa bu proses uğursuz ola bilər.

Hesablar tənzimləmələrində qaralamalar qovluğunu əllə seçərək bu problemi həll edə bilərsiniz (Tənzimləmələr > Əllə quraşdırma > Hesablar > ən altdakı hesaba toxunun). Heç bir qaralama qovluğu yoxdursa, hesabın qovluq siyahısındakı "+" düyməsinə toxunaraq qaralamalar qovluğunu yarada bilərsiniz (naviqasiya menyusundakı hesab adına toxunun).

Gmail kimi bəzi təchizatçılar, fərdi qovluqlar üçün IMAP-ın fəallaşdırılmasına/sıradan çıxarılmasına icazə verir. Ona görə də, əgər bir qovluq görünmürsə, qovluq üçün IMAP-ı fəallaşdırmalısınız.

Gmail üçün cəld bağlantı (yalnız masaüstü kompüterdə işləyəcək): https://mail.google.com/mail/u/0/#settings/labels


(142) Gələn qutusunda göndərilən mesajları necə saxlaya bilərəm?

Ümumiyyətlə, geri alınması çətin olduğu və digər e-poçt müştəriləri ilə uyğunsuz ola biləcəyi üçün gələn qutusunda göndərilən mesajları saxlamaq heç də yaxşı fikir deyil.

Əlavə olaraq FairEmail, göndərilən mesajları gələn qutusunda düzgün formada emal edə bilər. FairEmail, misal üçün gedən mesajları göndərilmiş mesajlar nişanı ilə işarələyəcək.

Ən yaxşı həll yolu, qovluq siyahısındakı göndərilənlər qovluğuna uzun basaraq və Birləşmiş gələn qutusunda göstər seçimini fəallaşdıraraq, birləşmiş gələn qutusundakı göndərilənlər qovluğunun göstərilməsini fəallaşdırmaqdır. Beləcə bütün mesajlar aid olduğu yerdə qala bilər, həmçinin həm gələn, həm də gedən mesajlara tək bir yerdə baxmağınıza şərait yaradır.

Bu bir seçim deyilsə, mesajların avtomatik olaraq gələn qutusuna köçürülməsi üçün bir qayda yarada və ya özünüzə bir kopyasını göndərmək üçün qabaqcıl kimlik tənzimləmələrində ilkin bir CC/BCC ünvanı tənzimləyə bilərsiniz.


(143) POP3 hesabları üçün bir tullantı qovluğu əlavə edə bilərsiniz?

POP3 həddindən artıq limitli protokoldur. Əsasən mesajlar yalnız gələn qutusundan endirilə və silinə bilər. Bir mesajı oxundu kimi işarələmək belə mümkün deyil.

POP3, tullantı qovluğuna müraciətə heç bir halda icazə vermədiyi üçün, tullantı qovluğundakı mesajları bərpa etməyin heç bir yolu yoxdur.

Yerli bir tullantı qovluğundakı kimi mesajların bərpa edilə biləcəyini təklif etməzdən əvvəl, mesajları gizlədə və gizli mesajları axtara biləcəyinizi unutmayın. Ancaq bu əslində mümkün deyil.

1.1082 versiyasında yerli bir tullantı qovluğu əlavə edilib. Unutmayın ki, bir mesajı tullantı qovluğuna atanda, həmin mesaj serverdən birdəfəlik silinir və tullantıya atılmış mesajlar heç bir halda serverdə bərpa edilə bilmir.


(144) Səsli qeydləri necə yaza bilərəm?

Səsli qeydləri yazmaq üçün mesaj yaradıcının alt hərəkət sətrindəki bu nişana basa bilərsiniz:

Xarici təsvir

Bunun üçün uyğun bir səsyazan tətbiq quraşdırılmalıdır. Xüsusilə də bu ortaq məqsədin dəstəklənməsi lazımdır.

Misal üçün bu səsyazan uyğundur.

Səsli qeydlər avtomatik olaraq əlavə edilir.


(145) Bir hesab, qovluq və ya göndərən üçün bildiriş səsini necə tənzimləyə bilərəm?

Hesab:

  • Qabaqcıl hesab tənzimləmələrində Ayrı bildirişlər seçimini fəallaşdırın (Tənzimləmələr > Əllə quraşdırma > Hesablar > Hesab > Qabaqcıl)
  • Hesab siyahısındakı hesaba uzun basın (Tənzimləmələr > Əllə quraşdırma > Hesablar) və bildiriş səsini dəyişdirmək üçün Bildiriş kanalına düzəliş et seçimini seçin

Qovluq:

  • Qovluq siyahısındakı bir qovluğa uzun basın və Bildiriş kanalı yarat seçimini seçin
  • Qovluq siyahısındakı bir qovluğa uzun basın və bildiriş səsini dəyişdirmək üçün Bildiriş kanalına düzəliş et seçimini seçin

Göndərən:

  • Göndərəndən bir mesajı açın və genişləndirin
  • Aşağı oxa toxunaraq ünvanlar bölməsini genişləndirin
  • Bir bildiriş kanalı yaratmaq və ya kanala düzəliş etmək və bildiriş səsini dəyişdirmək üçün zınqırov nişanına toxunun

Üstünlük sırası: göndərən səsi, qovluq səsi, hesab səsi və ilkin səs.

Bir hesab, qovluq və ya göndərən üçün bildiriş səsini tənzimləmək, Android 8 Oreo və ya daha yuxarı versiyanı tələb edir və bu Pro özəllikdir.


(146) Yanlış mesaj vaxtlarını necə düzəldə bilərəm?

Göndərilən tarix/vaxt ixtiyari olduğu və göndərən tərəfindən dəyişdirilə bildiyi üçün, FairEmail ilkin olaraq serverin alınan tarix/vaxtını istifadə edir.

Bəzən serverin alınan tarix/vaxtı yanlış olur, əksər hallarda mesajlar başqa serverdən yanlış formada idxal edildiyi üçün və bəzən də e-poçt serverindəki bir xətaya görə bu baş verir.

Belə nadir hallarda, "FairEmail"in ya Tarix başlığından (göndərilən vaxt), ya da Alındı başlığından tarix/vaxtı müvəqqəti həll yolu kimi istifadə etməsinə icazə vermək mümkündür. Bu, qabaqcıl hesab tənzimləmələrində dəyişdirilə bilər: Tənzimləmələr > Əllə quraşdırma > Hesablar > Hesab > Qabaqcıl.

Bu, əvvəlcədən eyniləşdirilmiş mesajların vaxtını dəyişdirmir. Bunu həll etmək üçün qovluq siyahısında qovluq(lar)a uzun basın və Yerli mesajları sil və İndi eyniləşdir seçimlərini seçin.


(147) Üçüncü tərəf versiyalar haqqında nə bilməliyəm?

Böyük ehtimalla bura "FairEmail"in üçüncü tərəf quraşdırmasını istifadə etdiyiniz üçün gəldiniz.

Yalnız bu versiyalarda dəstək var: Ən son Play Store versiyası, ən son GitHub buraxılışı və F-Droid quruluşu. Ancaq burada F-Droid quruluşunun versiya nömrəsi ilə ən son GitHub buraxılışının versiya nömrəsinin eyni olması şərti ödənilməlidir.

F-Droid quruluşu qeyri-müntəzəmdir, yəni vacib bir yeniləmə olanda problem yarada bilər. Ona görə də GitHub buraxılışına keçməyiniz məsləhət görülür.

F-Droid versiyası eyni mənbə kodundan istifadə olunaraq qurulub, ancaq fərqli formada imzalanıb. "Google"un yalnız bir tətbiqin imzalamasını təsdiqlədiyi (və icazə verdiyi) üçün Gmail cəld quraşdırma sehrbazının istifadəsi istisna olmaqla, bütün özəlliklər F-Droid versiyası üçün mövcuddur. E-poçt təchizatçıları yalnız rəsmi quruluşlar üçün "OAuth"un istifadəsinə icazə verdiyinə görə, digər bütün e-poçt təchizatçıları üçün OAuth müraciəti yalnız Play Store versiyalarında və GitHub buraxılışlarında mövcuddur.

Android, təhlükəsizlik səbəblərinə görə eyni tətbiqi fərqli bir imza ilə quraşdırmağı rədd etdiyi üçün, GitHub buraxılışını quraşdırmazdan əvvəl F-Droid quruluşunu silmək lazım olduğunu unutmayın.

GitHub versiyasının, yeniləmələri avtomatik yoxlayacağını unutmayın. İstəsəniz, bunu "Qarışıq" tənzimləmələrində bağlaya bilərsiniz.

Bütün endirmə seçimləri üçün zəhmət olmasa bura baxın.

F-Droid quruluşu ilə bağlı problem yaşayırsınızsa, zəhmət olmasa əvvəlcə yeni bir GitHub versiyasının mövcud olub-olmadığını yoxlayın.


(148) Bir Apple iCloud hesabını necə istifadə edə bilərəm?

Apple iCloud üçün daxili quraşdırılmış bir profil var, ona görə də cəld quraşdırma sehrbazını istifadə edə bilməlisiniz (digər təchizatçı). Lazım olarsa, əllə bir hesabı quraşdırmaq üçün doğru tənzimləmələri burada tapa bilərsiniz.

İki mərhələli kimlik təsdiqləmə istifadə edərkən tətbiq-xüsusi şifrəsinə ehtiyac yarana bilər.


(149) Oxunmamış mesaj sayı viceti necə işləyir?

Oxunmamış mesajı viceti, bütün hesablar və ya seçilmiş bir hesab üçün oxunmamış mesajını göstərir. Yalnız yeni mesaj bildirişlərinin fəal olduğu qovluqlar üçün işləkdir.

Bildirişə toxunarkən, eyniləşdirmənin fəal olduğu bütün qovluqlar üçün eyniləşdirmə baş tutacaq və açılacaq:

  • bütün hesablar seçiləndə başlanğıc ekranı
  • xüsusi bir hesab seçiləndə və bir neçə qovluq üçün yeni mesaj bildirişləri fəal olanda bir qovluq siyahısı
  • xüsusi bir hesab seçiləndə və bir qovluq üçün yeni mesaj bildirişləri fəal olanda mesajların bir siyahısı

(150) "Təqvim dəvətlərindən imtina etmə" özəlliyini əlavə edə bilərsiniz?

Təqvim dəvətlərindən imtina etmə (təqvim tədbirlərini silmə), təqvim yazma icazəsini tələb edir, bu da, bütün təqvimlərin bütün təqvim tədbirlərini oxuma və ya yazma icazəsinin effektiv şəkildə verilməsi ilə nəticələnəcək.

"FairEmail"in məqsədi gizlilik və təhlükəsizliyə fokuslanmaqdır, bir təqvim tədbirinin əllə çıxarılması asan olduğu üçün, sadəcə bu səbəbə görə bu icazəni tələb etmək heç də yaxşı bir fikir deyil.

Yeni təqvim tədbirlərinin daxil edilməsi, xüsusi məqsədlər üçün icazə olmadan edilə bilər. Təəssüf ki, mövcud təqvim tədbirlərini silmə məqsədi yoxdur.


(151) Mesajların nüsxələnməsi/bərpası üçün özəllik əlavə edə bilərsiniz?

Bir e-poçt müştərisi (client), mesajları nüsxələmək və bərpa etmək üçün deyil, mesajları oxumaq və yazmaq üçündür. Unutmayın ki, cihazınızı zədələsəniz və ya itirsəniz, mesajlarınız da itəcək!

Bunun əvəzində, mesajların nüsxələnməsi üçün məsuliyyəti e-poçt təchizatçısı/serveri daşıyır.

Özünüz bir nüsxələmə etmək istəyirsinizsə, imapsync kimi bir alət istifadə edə bilərsiniz.

1.1556 versiyasından etibarən, bir POP3 qovluğunun bütün mesajlarını RFC4155-ə görə mbox formatında ixrac edilməsi mümkündür, bu, e-poçt serveri bunu etmədiyi halda, göndərilən mesajların saxlanılması üçün faydalı olacaq.

Bir mbox faylını mövcud bir e-poçt hesabına idxal etmək istəyirsinizsə, "Thunderbird"i masaüstü kompüterdə və ImportExportTools-u səyyah əlavəsində istifadə edə bilərsiniz.


(152) Bir əlaqə qrupunu necə daxil edə bilərəm?

Mesaj yaradıcının üç nöqtə menyusu vasitəsilə bir əlaqə qrupuna bütün əlaqələrin e-poçt ünvanlarını daxil edə bilərsiniz.

Android əlaqələr tətbiqi ilə əlaqə qruplarını müəyyənləşdirə bilərsiniz, təlimatlar üçün zəhmət olmasa bura baxın.


(153) Gmail mesajını birdəfəlik silmək nə üçün işləmir?

İşləməsi üçün masaüstü səyyahda Gmail IMAP tənzimləmələrini dəyişdirməlisiniz:

  • IMAP-da bir mesajı silindi olaraq işarələyəndə: Avto-silmə bağlıdır - Müştərinin serveri yeniləməsini gözləyin.
  • Bir mesajı silindi olaraq işarələyəndə və son görünən IMAP qovluğundan silinəndə: Dərhal mesajı birdəfəlik silin

Unutmayın ki, arxivlənən mesajlar yalnız əvvəlcə tullantı qovluğuna köçürülərək silinə bilir.

Bəzi arxaplan: Gmail, IMAP üçün əsas mesaj görünüşündən fərqli ola bilən əlavə mesaj görünüşə sahibdir kimi görünür.

Başqa bir qəribəlik də odur ki, veb interfeys üzərindən tənzimlənən bir ulduz (sevimli mesaj) IMAP əmri ilə çıxarıla bilmir

STORE <message number> -FLAGS (\Bayraqlı)

Digər tərəfdən, IMAP üzərindən tənzimlənən bir ulduz veb interfeysdə görünür və IMAP üzərindən çıxarıla bilir.


(154) "Favicon"ları əlaqə fotoları kimi əlavə edə bilərsiniz?

Bundan əlavə bir favicon eyni domen adına sahib bir neçə e-poçt ünvanı tərəfindən paylaşıla bilər və buna görə də birbaşa e-poçt ünvanı ilə əlaqəli deyil, "favicon"lar sizi izləmək üçün istifadə edilə bilər.


(155) winmail.dat faylı nədir?

winmail.dat faylı, yanlış konfiqurasiya edilmiş Outlook müştərisi tərəfindən göndərilir. Bu xüsusi Microsoft fayl formatı (TNEF), bir mesajı və bəlkə də qoşmaları ehtiva edir.

Bu fayl haqqında daha çox məlumatı buradan tapa bilərsiniz.

Nümunə üçün Letter Opener Android tətbiqi ilə baxa bilərsiniz.


(156) Bir Office 365 hesabını necə quraşdıra bilərəm?

Cəld quraşdırma sehrbazı ilə Office 365 (OAuth) seçilərək bir Office 365 hesabı quraşdırıla bilər.

Əgər sehrbaz uğursuz KİMLİK TƏSDİQLƏMƏ ilə nəticələnsə, IMAP və/və ya SMTP, hesab üçün sıradan çıxarıla bilər. Bu halda, administratordan IMAP və SMTP-ni fəallaşdırmağı xahiş etməlisiniz. Prosedur burada sənədləşdirilib.

Təşkilatınızda ilkin təhlükəsizlik tənzimləmələrini fəallaşdırmısınızsa, SMTP AUTH protokolunu fəallaşdırmalısınız. Bunun necə edildiyinə burada baxa bilərsiniz.


(157) Bir Free.fr hesabını necə quraşdıra bilərəm?

Təlimatlar üçün zəhmət olmasa bura baxın.

SMTP ilkin olaraq sıradan çıxarılıb, necə fəallaşdırılacağına buradan baxa bilərsiniz.

Ətraflı bələdçi üçün zəhmət olmasa bura baxın.


(158) Hansı kamera/səsyazanı tövsiyə edirsiniz?

Foto çəkmək və səs yazmaq üçün bir kamera və səsyazan tətbiq lazımdır. Aşağıdakı tətbiqlər, açıq mənbəli kamera və səsyazanlardır:

Səsli qeydləri yazmaq üçün, səsyazan bunları dəstəkləməlidir: MediaStore.Audio.Media.RECORD_SOUND_ACTION. Qəribəlik odur ki, əksər səsyazanlar, bu standart Android əməliyyatını dəstəkləyir kimi görünür.


(159) "Disconnect"in izləyici qoruma siyahısı nələrdir?

"Disconnect"in izləyici qoruma siyahısı haqqında daha ətraflı məlumat üçün zəhmət olmasa bura baxın.

Siyahılar gizlilik tənzimləmələrində endirildikdən sonra, ixtiyari olaraq istifadə edilə bilər:

  • açılış bağlantılarında izləmə bağlantıları haqqında xəbərdarlıq etmək üçün
  • mesajlardakı izləmə təsvirlərini tanımaq üçün

İzləmə təsvirləri, yalnız əlaqəli əsas "sıradan çıxart"ma seçimi fəal olarsa, sıradan çıxarılacaq.

Domen adı "Məzmun" kimi sinifləşdiriləndə izləmə təsvirləri tanınmayacaq, daha ətraflı məlumata buradan baxa bilərsiniz.

Bu əmr, qoruma siyahılarını yeniləmək üçün bir avtomatlaşdırma tətbiqindən "FairEmail"ə göndərilə bilər:

(adb shell) am start-foreground-service -a eu.faircode.email.DISCONNECT.ME

Həftəlik yeniləmə böyük ehtimal yetərli olacaq, son siyahı dəyişikləri üçün zəhmət olmasa bura baxın.


(160) Təsdiq olmadan mesajların birdəfəlik silinməsini əlavə edə bilərsiniz?

Birdəfəlik silmə, geri dönüşü olmadan mesajların itməsi deməkdir və bunun təsadüfən baş verməsinin qarşısını almaq üçün, bu həmişə təsdiqlənməlidir. Hətta bir təsdiqlə belə, mesajlarının bir qismini öz səhvi üzündən silən bəzi əsəbi insanlar mənimlə əlaqə saxladı, bu olduqca xoşagəlməz bir təcrübə idi :-(

Qabaqcıl: EXPUNGE əmri ilə birgə IMAP silmə bayrağı dəstəklənmir, çünki həm e-poçt serverləri və həm də heç kim bunu ələ ala bilməz və mesajların gözlənilməz itkisi riski ilə üzləşər. Mürəkkəb bir faktor, bütün e-poçt serverlərinin UID EXPUNGE-i dəstəkləməməsidir.

1.1485 versiyasından etibarən mesajların silinməsini sıradan çıxartmaq üçün "Qarışıq" tənzimləmələrdə sazlama rejimini müvəqqəti olaraq fəallaşdırmaq mümkündür. \Silindi olaraq bayraqlanmış mesajların "FairEmail"də göstərilməyəcəyini unutmayın.


(161) Əsas və vurğu rəngini dəyişdirmək üçün bir tənzimləmə əlavə edə bilərsiniz?*

Edə bilsəydim, dərhal əsas və vurğu rəngini seçmək üçün bir tənzimləmə əlavə edərdim, ancaq təəssüf ki, Android temaları düzəldildi, nümunə üçün bura baxın, yəni, bu mümkün deyil.


(162) IMAP NOTIFY dəstəklənir?*

Bəli, IMAP NOTIFY 1.1413 versiyasından etibarən dəstəklənir.

IMAP NOTIFY dəstəyi, bütün abunə olunan qovluqların əlavə edilən, dəyişdirilən və ya silinən mesajlar üçün bildiriş tələb olunacağı və abunə olunan bir qovluq üçün bir bildiriş alınarsa, həmin qovluğun eyniləşdiriləcəyini mənasına gəlir. Buna görə də, abunə olunan qovluqlar üçün eyniləşdirmə ləğv edilə bilər, qovluq bağlantıları e-poçt serverində saxlanılır.

Vacib: gələn qutusu və abunəlik idarəetməsi (alma tənzimləmələri) üçün ani mesajlar (=həmişə eyniləşdirmə) fəallaşdırılmalıdır.

Vacib: əksər e-poçt serverləri bunu dəstəkləmir! Əgər bir e-poçt serveri NOTIFY özəlliyini dəstəkləyirsə, jurnalı naviqasiya menyusu ilə yoxlaya bilərsiniz.


(163) Mesajların sinifləşdirilməsi nədir?

Bu bir təcrübi özəllikdir!

Mesaj sinifləşdirilməsi, Bayes statistikalarını istifadə edərək e-poçtları, onların məzmunlarına görə avtomatik olaraq siniflərə qruplaşdırmağa çalışacaq. FairEmail konteksində bir qovluq, bir sinifdir. Məsələn, gələn qutusu, spam qovluğu, bir "marketinq" qovluğu və s.

"Qarışıq" tənzimləmələrində mesaj sinifləşdirməsini fəallaşdıra bilərsiniz. Bu, yalnız "öyrənmə" rejimini fəallaşdıracaq. Sinifləşdirici, ilkin olaraq gələn qutusu və spam qovluğundakı yeni mesajlardan "öyrənəcək". Yeni mesajları bu qovluqda sinifləşdir qovluq özəlliyi, bir qovluq üçün "öyrənmə" rejimini fəallaşdıracaq və ya sıradan çıxardacaq. Yerli mesajları təmizləyə (bir hesabın qovluq siyahısındakı bir qovluğa uzun basaraq) və mövcud mesajları sinifləşdirmək mesajları üçün təkrar eyniləşdirə bilərsiniz.

Hər bir qovluğun Sinifləşdirilmiş mesajları avtomatik olaraq bu qovluğa köçürt seçimi var (qısaca "avto-sinifləşdirmə"). Bu seçim işə salınanda, sinifləşdiricinin o qovluğa aid olduğunu düşündüyü digər qovluqlardakı yeni mesajlar, avtomatik olaraq köçürüləcək.

Spam bildirmə dialoq pəncərəsindəki Yerli spam filtrini istifadə et seçimi, "Qarışıq" tənzimləmələrindəki mesaj sinifləşdirməsini və spam qovluğu üçün avto-sinifləşdirməni işə salacaq. Zəhmət olmasa bunun e-poçt serverinin spam filtrini əvəz etmədiyini və yanlış pozitiv və neqativlər ilə nəticələnə biləcəyini anlayın. Həmçinin TSS-a baxın.

Praktik bir nümunə: fərz edək ki, bir "marketinq" qovluğu var və bu qovluq üçün mesajların avto-sinifləşdirilməsi fəaldır. Hər dəfə bir mesajı bu qovluğa köçürəndə, "FairEmail"ə, oxşar mesajların bu qovluğa aid olduğunu öyrədəcəksiniz. Hər dəfə bir mesajı bu qovluqdan çıxaranda, "FairEmail"ə, oxşar mesajların bu qovluğa aid olmadığını öyrədəcəksiniz. Bəzi mesajları "marketinq" qovluğuna köçürdükdən sonra, FairEmail, oxşar mesajları avtomatik olaraq bu qovluğa köçürməyə başlayacaq. Və ya tam tərsi, bəzi mesajları "marketinq" qovluğundan çıxaranda, FairEmail, oxşar mesajları avtomatik olaraq bu qovluğa köçürməyi dayandıracaq. Bu, oxşar məzmunlu (e-poçt ünvanları, mövzu və mesaj mətni) mesajlar üçün yaxşı nəticə verəcək.

Sinifləşdirmə ən yaxşı təxmin kimi düşünülməlidir - yanlış təxmin də ola bilər və ya sinifləşdirmə, hər hansısa təxmin üçün yetəri qədər əmin olmaya bilər. Əgər sinifləşdirmə əmin deyilsə, sadəcə olduğu yerdə bir e-poçt buraxacaq.

E-poçt serverinin bir mesajı təkrar olaraq spam qovluğuna köçürməsinin qarşısını almaq üçün, spam qovluğunda avto-sinifləşdirmə edilməyəcək.

Mesaj sinifləşdirici, bir mesajın bir qovluğa (sinif) aid olma ehtimalını hesablayır. "Qarışıq" tənzimləmələrdə bir mesajın avtomatik olaraq bir qovluğa köçürülüb-köçürülməyəcəyinə nəzarət edən iki seçim var - qovluq üçün avto-sinifləşdirmənin fəal olması halında:

  • Minimum sinif ehtimalı: yalnız bir mesajın bir qovluğa aid olduğunu hesablayan güvən dəyəri bu dəyərdən böyük olanda mesaj köçürüləcək (ilkin 15%)
  • Minimum sinif fərqi: bir sinif ilə digər ehtimal olunan sinif arasındakı güvən fərqi bu dəyərdən böyük olanda mesaj köçürüləcək (ilkin 50%)

Bir mesajın köçürülməsi üçün hər iki şərt də ödənilməlidir.

İlkin seçim dəyərləri nəzərə alınanda:

  • Almalar 40% və bananlar 30% nəzərə alınmır, çünki 25%-lik fərq, minimum 50%-in altındadır
  • Almalar 10% və bananlar 5% nəzərə alınmır, çünki alma ehtimalı minimum 15%-in altındadır
  • Almalar 50% və bananlar 20%-dirsə, almalar seçilir

Sinifləşdirmə mümkün olduğu qədər az mənbə istifadə etməsi üçün optimallaşdırılıb, ancaq istər-istəməz əlavə batareya enerji istifadəsi mümkündür.

"Qarışıq" tənzimləmələrdə sinifləşdirməni üç dəfə bağlayaraq, bütün sinifləşdirmə verilənlərini silə bilərsiniz.

Filtr qaydaları sinifləşdirmədən əvvəl icra edilir.

Mesajlar sinifləşdirmə, spam qovluğu istisna olmaqla bir Pro özəllikdir.


(164) Özəlləşdirilə bilən temalar əlavə edə bilərsiniz?

Təəssüf ki, Android dinamik temaları dəstəkləmir, bu da o deməkdir ki, bütün temalar əvvəlcədən təyin edilməlidir.

Hər tema üçün açıq, tünd və qara variant olmasına ehtiyac yarandığı üçün hər bir rəng kombinasiyası üçün (sözün əsl mənasında milyonlarla) əvvəlcədən təyin edilmiş tema əlavə etmək mümkün deyil.

Həmçinin, bir tema, bir neçə rəngdən daha çoxudur. Misal üçün, sarı vurğu rənginə sahib temalar yetərli ziddiyyət üçün daha tünd bağlantılı rəng istifadə edir.

Tema rəngləri, Johannes Itten-in rəng dairəsinə əsaslanır.


(165) Android Avto dəstəklənir?

Bəli, Android Avto dəstəklənir, ancaq yalnız GitHub versiyası ilə, səbəbi üçün zəhmət olmasa bura baxın.

Bildiriş (mesajlaşma) dəstəyi üçün aşağıdakı bildiriş seçimlərini fəallaşdırmalısınız:

  • Android "mesajlaşma stili" bildiriş formatını istifadə edin
  • Bildiriş əməliyyatları: Birbaşa cavab və (işarələ) Oxundu

İstəsəniz digər bildiriş əməliyyatlarını da fəallaşdıra bilərsiniz, ancaq onlar Android Avto tərəfindən dəstəklənmir.

Tərtibatçıların bələdçisi buradadır.


(166) Bir mesajı bir neçə cihazda ertələyə bilərəm?

Hər şeydən əvvəl, mesajları ertələmək üçün heç bir standart yoxdur, ona görə də ertələmə tətbiqləri özəl həll yollarıdır.

Gmail kimi bəzi e-poçt təchizatçıları, ertələnən mesajları xüsusi bir qovluğa köçürdür. Təəssüflər olsun ki, üçüncü tərəf tətbiqlərin bu xüsusi qovluğa müraciəti yoxdur.

Bir mesajı başqa bir qovluğa köçürmə və geri qaytarma prosesi uğursuz ola bilər və internet bağlantısı olmadıqda mümkün olmaya bilər. Bu problemlidir, çünki bir mesaj, ancaq mesaj köçürüldükən sonra ertələnə bilər.

Bu problemlərin qarşısını almaq üçün, ertələmə, ertələmə zamanı mesaj gizlədilərək cihazın yaddaşında həyata keçirilir. Təəssüflər olsun ki, e-poçt serverində də mesajları gizlətmək mümkün deyil.


Dəstək al

FairEmail, yalnız Android ağıllı telefonlarında, planşetlərində və ChromeOS-da dəstəklənir.

Yalnız ən son Play Store versiyası və ən son GitHub buraxılışı dəstəklənir. F-Droid quruluşu, yalnız versiya nömrəsi ən son GitHub buraxılışının versiya nömrəsi ilə eynidirsə dəstəklənir. Bu da versiyanı aşağı salmanın dəstəklənməməsi deməkdir.

"FairEmail" ilə birbaşa əlaqədə olmayan şeylər üçün dəstək yoxdur.

Özünüz üçün quruluş və tərtibat prosesini icra etməkdə heç bir dəstək yoxdur.

Tələb edilən özəlliklər:

  • əksər insan üçün faydalı olması
  • "FairEmail"in istifadəsini mürəkkəbləşdirməməsi
  • "FairEmail"in fəlsəfəsinə uyğun olması (gizlilik yönümlü, təhlükəsizliyə fokuslanmış)
  • ortaq standartlara uyğun gəlməsi (IMAP, SMTP və s.)

Bu tələbləri qarşılamayan özəlliklər böyük ehtimalla rədd ediləcək. Bu da eyni zamanda uzunmüddətli qulluğu və dəstəyi davam etdirmək üçündür.

Bir sualınız varsa, bir özəllik tələb etmək və ya bir xəta bildirmək istəyirsinizsə zəhmət olmasa bu formu istifadə edin.

GitHub problemləri, tez-tez yanlış istifadə edildiyinə görə sıradan çıxarıldı.
