Supporto FairEmail

Se hai una domanda, controlla prima le domande frequenti qui sotto. In fondo puoi trovare come porre altre domande, richiedere funzionalità e segnalare errori.

Indice

Autorizzare account

Nella maggior parte dei casi, la configurazione rapida sarà in grado di identificare automaticamente la configurazione giusta.

Se la configurazione rapida fallisce, dovrai configurare manualmente un account (per ricevere email) e un'identità (per inviare email). Per farlo avrai bisogno degli indirizzi dei server IMAP e SMTP e dei numeri delle porte, di sapere se SSL/TLS o STARTTLS devono essere usati e conoscere il tuo nome utente (solitamente, ma non sempre, il tuo indirizzo email) e la password.

Cercare IMAP e il nome del fornitore di solito è sufficiente per trovare la documentazione giusta.

In alcuni casi, dovrai abilitare l'accesso esterno al tuo account e/o utilizzare una password speciale (app), per esempio quando l'autenticazione a due fattori è attiva.

Per autorizzare:

Come fare per ...?

Problemi noti

  • Un errore in Android 5.1 e 6 causa la visualizzazione di un formato sbagliato delle ore. Attivando/disattivando l'impostazione di Android Usa il formato 24 ore potrebbe risolvere temporaneamente il problema. È stato aggiunto un espediente.
  • Un errore in Google Drive fa sì che i file esportati su Google Drive siano vuoti. Google lo ha corretto.
  • Un errore in AndroidX provoca un crash occasionale di FairEmail durante la pressione a lungo o lo scorrimento. Google lo ha corretto.
  • Un errore in AndroidX ROOM causa a volte un crash con "... Eccezione durante il calcolo dei dati live del database ... Impossibile leggere la riga ...". È stato aggiunto un espediente.
  • Un errore in Android causa un crash di FairEmail con "... Notifica errata postata ..." su alcuni dispositivi dopo l'aggiornamento di FairEmail e toccando su una notifica.
  • Un errore in Android a volte provoca un crash con "... ActivityRecord non trovato per ..." dopo l'aggiornamento FairEmail. La reinstallazione (source) potrebbe risolvere il problema.
  • Un errore in Android a volte provoca un crash con ... InputChannel non è inizializzato ... su alcuni dispositivi.
  • Un errore in LineageOS a volte provoca un crash con ... java.lang.ArrayIndexOutOfBoundsException: length=...; index=... ....
  • Un errore in Nova Launcher su Android 5.x causa il crash di FairEmail con un java.lang.StackOverflowError quando Nova Launcher ha accesso al servizio di accessibilità.
  • Il selettore di cartelle a volte non mostra cartelle per motivi ancora sconosciuti. Sembra essere risolto.
  • Un errore in AndroidX rende difficile toccare lo scroller rapido. È stato aggiunto un espediente.
  • La crittografia con YubiKey risulta in un ciclo infinito. Ciò sembra essere causato da un errore in OpenKeychain.
  • Lo scorrimento verso una posizione collegata internamente nei messaggi originali non funziona. Ciò non può essere risolto perché la vista originale dei messaggi è contenuta in una vista a scorrimento.
  • Un'anteprima di un testo di un messaggio non (sempre) appare negli orologi Samsung perché setLocalOnly sembra venga ignorato. Le anteprime dei messaggi sono note per essere visualizzate correttamente su Pebble 2, Fitbit Charge 3 e Mi band 3. Vedi anche queste domande frequenti.
  • Un errore in Android a volte provoca un crash con *... Spostamento non valido: ... L'intervallo valido è ... quando il testo è selezionato e tocca all'esterno del testo selezionato. Questo bug è stato risolto in Android 6.0.1.
  • I collegamenti interni (ancoraggi) non funzioneranno perché i messaggi originali sono mostrati in una WebView incorporata in una vista a scorrimento (l'elenco delle conversazioni). Questa è una limitazione di Android che non può essere fissata o lavorata.

Funzionalità pianificate

  • Sicronizzazione su richiesta (manuale)
  • Cifratura semi-automatica
  • Copia messaggio
  • Stelle colorate
  • Impostazioni di notifica per cartella
  • Selezione immagini locali per le firme (non verrà aggiunto perchè richiede la gestione dei file e quasi tutti i client email non mostrano le immagini per impostazione predefinita)
  • Mostra messaggi che soddisfano un criterio
  • ManageSieve (non ci sono librerie Java mantenute con licenza adeguata e senza dipendenze, inoltre FairEmail ha le proprie regole di filtraggio)
  • Cerca messaggi con/senza allegati (non può essere implementata perchè IMAP non supporta la ricerca degli allegati)
  • Cerca una cartella (il filtro su cartelle gerarchiche è problematico)
  • Suggerimenti di ricerca
  • Messaggio di configurazione Autocrypt (section 4.4) (Secondo me non è una buona idea permette ad un client di posta elettronica di gestire le chiavi di crittografia solo per casi d'uso rari se OpenKeychain può esportare anche le chiavi)
  • Cartelle unificate generiche
  • Programmazione notifiche nuovo messaggio per account (implementato aggiungendo regole di orario in modo che i messaggi possano essere silenziati durante periodi scelti)
  • Copiare account e identità
  • Zoom con selezione (non è possibile in modo affidabile in una lista scorrevole; si può invece ingrandire l'intero messaggio)
  • Visualizzazione delle cartelle più compatta
  • Creare liste e tabelle (richiede un rich text editor, vedi questa FAQ)
  • Pizzica ingrandimento della dimensione del testo
  • Mostra GIF
  • Temi (un tema grigio chiaro e scuro è stato aggiunto perché questo è ciò che gran parte delle persone sembrano di volere)
  • Ogni condizione dell'ora del giorno (ogni giorno non si adatta davvero nella condizione da/alla data/orario)
  • Invia come allegato
  • Widget per il profilo selezionato
  • Ricorda di allegare i file
  • Seleziona i domini per cui mostrare le immagini (questo sarà troppo complicato da usare)
  • Visualizzazione messaggi preferiti unificati (c'è già una ricerca speciale per questo)
  • Sposta azione di notifica
  • Supporto S/MIME
  • Cerca impostazioni

Qualsiasi cosa su questa lista è in ordine casuale e potrebbe essere aggiunto nel vicino futuro.

Funzionalità richieste di frequente

Il design è basato su molte discussioni e se vuoi puoi discuterne anche tu in questo forum. L'obiettivo del design è quello di essere minimalista (senza menu inutili, pulsanti, ecc.) e di non distrarre (senza colori fantasiosi, animazioni, ecc). Tutte le cose visualizzate devono essere utili in un modo o nell'altro e devono essere posizionate con attenzione per un facile utilizzo. Caratteri, dimensioni, colori, ecc devono essere in material design quando possibile.

Domande frequenti

Ho un'altra domanda.

(1) Quali permessi sono necessari e perché?

I permessi di Android seguenti sono necessari:

  • avere accesso completo alla rete (INTERNET): per inviare e ricevere le email
  • visualizza le connessioni di rete (ACCESS_NETWORK_STATE): per monitorare le modifiche alla connettività di internet
  • esegui all'avvio (RECEIVE_BOOT_COMPLETED): per avviare il monitoraggio all'avvio del dispositivo
  • servizio in primo piano (FOREGROUND_SERVICE): per eseguire un servizio in primo piano su Android 9 Pie e successive, vedi anche la prossima domanda
  • prevenire che il dispositivo vada in riposo (WAKE_LOCK): per mantenere attivo il dispositivo durante la sincronizzazione dei messaggi
  • fatturazione in-app (BILLING): per consentire gli acquisti in-app
  • Opzionale: leggi i tuoi contatti (READ_CONTACTS): per completare automaticamente gli indirizzi e mostrare le foto
  • Opzionale: leggere i contenuti della tua scheda SD (READ_EXTERNAL_STORAGE): per accettare i file da altre app obsolete, vedi anche questa FAQ
  • Opzionale: usa l'hardware delle impronte digitali (USE_FINGERPRINT) e usa l'hardware biometrico (USE_BIOMETRIC): per usare l'autenticazione biometrica
  • Opzionale: trova profili sul dispositivo (GET_ACCOUNTS): per selezionare un profilo quando si utilizza la configurazione rapida di Gmail
  • Android 5.1 e precedenti: usa profili sul dispositivo (USE_CREDENTIALS): per selezionare un profilo quando usi la configurazione rapida di Gmail (non necessario sulle versioni di Android successive)
  • Android 5.1 Lollipop e precedenti: Leggi profilo (READ_PROFILE): per leggere il tuo nome quando usi la configurazione rapida di Gmail (non necessario sulle versioni di Android successive)

I permessi opzionali sono supportati solo su Android 6 Marshmallow e successive. Sulle versioni precedenti di Android ti sarà chiesto di garantire i permessi opzionali per l'installazione di FairEmail.

I permessi seguenti sono necessari per mostrare il conteggio dei messaggi non letti come un distintivo (vedi anche questa 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 manterrà un elenco di indirizzi da cui ricevi e invii messaggi e userà questa lista per i suggerimenti di contatto quando non viene concesso alcun permesso di contatti a FairEmail. Ciò significa che puoi usare FairEmail senza il fornitore di contatti di Android (rubrica indirizzi). Nota che puoi ancora selezionare i contatti senza concedere i permessi dei contatti a FairEmail, solo suggerendo contatti non funzionerà senza i permessi dei contatti.


(2) Perché è mostrata una notifica permanente?

Una notifica della barra dello stato permanente a bassa priorità con il numero di profili monitorati e il numero di operazioni in attesa (vedi prossima domanda) è mostrata per prevenire che Android termini il servizio che si occupa della ricezione continua delle email. Questo era già necessario, ma con l'introduzione della doze mode in Android 6 Marshmallow questo è necessario più che mai. La modalità Doze interromperà tutte le app quando lo schermo è spento per un po' di tempo, a meno che l'app non abbia avviato un servizio in primo piano, che richiede la visualizzazione di una notifica della barra di stato.

La maggior parte, se non tutte, le altre app d'email non mostrano una notifica, con "effetto collaterale" che i nuovi messaggi sono spesso non segnalati o segnalati tardi e che i messaggi non sono inviati o inviati tardi.

Android mostra prima le icone delle notifiche della barra di stato di alta priorità e nasconderà l'icona della notifica di FairEmail se non c'è più spazio per mostrare le icone. In pratica ciò significa che la notifica della barra di stato non prende spazio nella barra di stato, a meno che non ci sia spazio disponibile.

La notifica della barra di stato può essere disabilitata tramite le impostazioni di notifica di FairEmail:

  • Android 8 Oreo e successive: tocca il pulsante Ricevi canale e disabilita il canale tramite le impostazioni di Android (questo non disabiliterà le notifiche dei messaggi)
  • Android 7 Nougat e precedenti: abilitato l'Uso del servizio in background per sincronizzare i messaggi, ma assicurati di leggere l'osservazione sotto l'impostazione

Puoi passare alla sincronizzazione dei messaggi periodicamente nelle impostazioni di ricezione per rimuovere la notifica, ma sii consapevole che ciò potrebbe usare maggiore energia della batteria. Vedi qui per ulteriori dettagli sull'uso della batteria.

Android 8 Oreo potrebbe anche mostrare una notifica della barra di stato con il testo Le app sono in esecuzione in background. Sei pregato di vedere qui su come puoi disabilitare questa notifica.

Alcune persone hanno suggerito di usare Firebase Cloud Messaging (FCM) invece di un servizio Android con una notifica della barra dello stato, ma questo richiederebbe ai fornitori dell'email di inviare messaggi FCM ad o ad un server centrale dove sono raccolti tutti i messaggi di inviare messaggi FCM. La prima non si verificherà è l'ultima avrà significative implicazioni sulla privacy.

Se sei venuto/a qui cliccando sulla notifica, dovresti sapere che il prossimo clic aprirà la casella di posta unificata.


(3) Cosa sono le operazioni e perché sono in sospeso?

La notifica della barra dello stato a bassa priorità mostra il numero di operazioni in sospeso, che possono essere:

  • add: aggiungi messaggio alla cartella remota
  • move: sposta messaggio ad un'altra cartella remota
  • copy: copia messaggio in un'altra cartella remota
  • fetch: preleva il messaggio modificato (spinto)
  • delete: elimina il messaggio dalla cartella remota
  • seen: contrassegna il messaggio come letto/non letto nella cartella remota
  • answered: contrassegna il messaggio come risposto nella cartella remota
  • flag: aggiunge/rimuove la stella nella cartella remota
  • keyword: aggiunge/rimuove il flag IMAP nella cartella remota
  • label: imposta/ripristina l'etichetta di Gmail nella cartella remota
  • headers: scarica le intestazioni dei messaggi
  • raw: scarica il messaggio grezzo
  • body: scarica il testo del messaggio
  • attachment: scarica l'allegato
  • sync: sincronizza i messaggi locali e remoti
  • subscribe: si iscrive alla cartella remota
  • purge: elimina tutti i messaggi dalla cartella remota
  • send: invia messaggio
  • exists: controlla se il messaggio esiste
  • rule: esegui regola sul corpo del testo

Le operazioni sono elaborate solo quando esiste una connessione al server email o quando sincronizza manualmente. Vedi anche questa FAQ.


(4) Come posso usare un certificato di sicurezza non / password vuota / connessione di testo semplice?

... Non affidabile ... non nel certificato ...
... Certificato di sicurezza non valido (Impossibile verificare l'identità del server) ...

Dovresti provare a risolvere ciò contattando il tuo fornitore o ottenendo un certificato di sicurezza valido perché i certificati di sicurezza non validi non sono sicuri e consente gli attacchi man-in-the-middle. Se il denaro è un ostacolo, puoi ottenere dei certificati di sicurezza gratuiti da Let's Encrypt.

In alternativa, puoi accettare le impronte digitali mostrate sotto il messaggio di errore se configuri il profilo e/o l'identità nei passaggi 1 e 2 della configurazione (non è possibile usando la procedura guidata di configurazione rapida). Nota che dovresti assicurarti che la connessione ad internet che stai usando sia sicura.

Nota che le versioni precedenti potrebbero non riconoscere le autorità di certificazione più nuove come Let's Encrypt, causando alle connessioni di essere considerate non sicure, vedi anche qui.

Ancoraggio di fiducia per il percorso di certificazione non trovato

... 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.

Dovresti correggere la configurazione del server o accettare l'impronta digitale mostrata sotto il messaggio d'errore.

Nota che questo problema può essere causato dal server che non invia anche certificati intermedi.

Password vuota

Il tuo nome utente è probabilmente facilmente individuato, quindi ciò non è sicuro.

Connessione del testo semplice

Il tuo nome utente e la password e tutti i messaggi saranno inviati e ricevuti non crittografati, il che è molto insicuro perché un attacco man-in-the-middle è molto semplice su una connessione non crittografata.

Se vuoi ancora usare un certificato di sicurezza non valido, una password vuota o una connessione del testo semplice dovrai abilitare le connessioni non sicure nelle impostazioni del profilo e/o dell'identità. STARTTLS dovrebbe essere selezionato per le connessioni in testo semplice. Se abiliti connessioni non sicure, dovresti connetterti solo tramite reti private e attendibili e mai tramite reti pubbliche, come quelle offerte in hotel, aeroporti, ecc.


(5) Come posso personalizzare la visualizzazione dei messaggi?

Nel menu di overflow a tre punti è possibile abilitare o disabilitare o selezionare:

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

Nella sezione di visualizzazione delle impostazioni puoi abilitare o disabilitare:

  • Casella unificata: per disabilitare la casella della posta in arrivo unificata ed elencare le cartelle selezionate invece per la casella di posta in arrivo unificata
  • Group by date: mostra l'intestazione di data sui messaggi con la stessa data
  • Conversation threading: to disable conversation threading and to show individual messages instead
  • Mostra foto dei contatti: per nascondere le foto di contatto
  • Mostra identicon: per mostrare gli avatar di contatto generati
  • Mostra nomi ed indirizzi email: per mostrare nomi o mostrare nomi ed indirizzi email
  • Mostra soggetto corsivo: per mostrare il soggetto del messaggio come testo normale
  • Mostra stelle: per nascondere le stelle (preferiti)
  • Mostra anteprima messaggio: per mostrare due righe del testo del messaggio
  • Mostra dettagli dell'indirizzo di default: per espandere la sezione degli indirizzi di default
  • Usa carattere monospaziato per il testo del messaggio: per usare un tipo di testo di larghezza fissa per i testi del messaggio
  • Mostra automaticamente il messaggio originale per i contatti noti: per mostrare automaticamente i messaggi originali per i contatti sul tuo dispositivo, sei pregato di leggere questa FAQ
  • Automatically show images for known contacts: to automatically show images for contacts on your device, please read this FAQ
  • Barra di azione della conversazione: per disabilitare la barra di navigazione in basso

Nota che i messaggi possono essere visti in anteprima solo quando il testo del messaggio è stato scaricato. I testi del messaggio più grandi non sono scaricati di default sulle reti misurate (generalmente mobili). Puoi modificare ciò nelle impostazioni.

Se l'elenco degli indirizzi è lungo, puoi comprimere la sezione degli indirizzi con l'icona meno nella parte superiore della sezione degli indirizzi.

Alcune persone chiedono:

  • di mostrare il soggetto in grassetto, ma il grassetto è già usato per evidenziare i messaggi non letti
  • di mostrare l'indirizzo o l'oggetto più grande/più piccolo, ma questo interferirebbe con l'opzione di dimensione del testo
  • di spostare la stella a sinistra, ma è molto più facile azionarla sul lato destro

Sfortunatamente, è impossibile rendere tutti felici ed aggiungere molte impostazioni non sarebbe solo confusionario, ma anche mai sufficiente.


(6) Come posso accedere a Gmail / G suite?

Puoi usare la procedura guidata di configurazione rapida per configurare facilmente un profilo ed un'identità di Gmail.

Se non vuoi usare un profilo Gmail sul dispositivo, puoi abilitare l'accesso per le "app meno sicure" ed usare la password del tuo profilo (sconsigliato) o abilitare l'autenticazione a due fattori ed usare una password specifica dell'app. Per usare una password dovrai configurare un profilo ed un'identità tramite i passaggi 1 e 2 della configurazione invece che tramite la procedura guidata di configurazione rapida.

Sei pregato di vedere questa FAQ su perché solo i profili su dispositivo sono utilizzabili.

Nota che una password specifica dell'app è necessaria quando è abilitata l'autenticazione a due fattori.


Password specifica dell'app

Vedi qui su come generare una password specifica dell'app.


Abilita "App meno sicure"

Importante: usare questo metodo è sconsigliato perché meno affidabile.

Importante: I profili autorizzati di Gsuite con un nome utente/una password smetteranno di funzionare nel futuro prossimo.

Vedi qui su come abilitare le "app meno sicure" o vai direttamente all'impostazione.

Se usi profili multipli di Gmail, assicurati di cambiare l'impostazione "app meno sicure del profilo corretto.

Sappi che devi lasciare la schermata delle impostazioni delle "app meno sicure" usando la freccia indietro per applicare l'impostazione.

Se usi questo metodo, dovresti usare una password forte per il tuo profilo Gmail, che è comunque una buona idea. Nota che di per se, usare il protocollo IMAP standard non è meno sicuro.

Quando "app meno sicure" non è abilitata, otterrai l'errore Autenticazione fallita - credenziali non valide per i profili (IMAP) e Nome utente e Password non accettati per le identità (SMTP).


Generale

Potresti ottenere l'avviso "Sei pregato di accedere tramite il tuo browser web". Questo si verifica quando Google considera la rete cui ti connetti ad internet (potrebbe essere un VPN) come non sicura. Questo si può prevenire usando la procedura guidata di configurazione rapida di Gmail o una password specifica dell'app.

Vedi qui per le istruzioni di Google e qui per la risoluzione dei prbolemi.


(7) Perché i messaggi inviati non compaiono (direttamente) nella cartella inviati?

I messaggi inviati sono normalmente spostati dalla posta in uscita alla cartella inviati appena il tuo fornitore aggiunge i messaggi inviati alla cartella dei messaggi inviati. Ciò richiede che una cartella inviati sia selezionata nelle impostazioni del profilo e che la cartella degli inviati sia impostata per la sincronizzazione.

Alcuni fornitori non tengono traccia dei messaggi inviati o il server SMTP usato potrebbe non essere correlato al fornitore. In questi casi, FairEmail, aggiungerà automaticamente i messaggi inviati alla cartella inviati alla sincronizzazione della cartella degli inviati, che si verificherà dopo che è un messaggio è stato inviato. Nota che questo risulterà in traffico internet supplementare.

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) Posso usare un profilo di Microsoft Exchange?

Puoi usare un profilo di Microsoft Exchange se è accessibile tramite IMAP, che lo è per lo più. Vedi qui per ulteriori informazioni.

Sei pregato di vedere qui per la documentazione di Microsoft sulla configurazione di un client di posta elettronica. Esiste anche una sezione sugli errori di connessione comuni e le soluzioni.

Alcune vecchie versioni del server di Exchange hanno un bug che causa messaggi vuoti ed allegati corrotti. Sei pregato di vedere questa FAQ per un workaround.

Sei pregato di vedere questa FAQ sul supporto di ActiveSync.

Sei pregato di vedere questaFAQ sul supporto di OAuth.


(9) Cosa sono le identità / come aggiungo un alias?

Le identità rappresentano gli indirizzi email da cui stai inviando tramite un server email (SMTP).

Alcuni provider ti consentono di avere alias multipli. Puoi confiurarli impostando il campo dell'indirizzo email di un'identità aggiuntiva all'indirizzo dell'alias e impostando il campo del nome utente al tuo indirizzo email principale.

Nota che puoi copiare un'identità tenendola premuta a lungo.

Alternativamente, puoi abilitare Consenti modifica indirizzo mittente nelle impostazioni avanzate di un'identità esistente per modificare il nome utente quando componi un nuovo messaggio, se il tuo fornitore lo consente.

FairEmail aggiornerà automaticamente le password delle identità correlate quando aggiorni la password del profilo associato o un'identità correlata.

Vedi questa FAQ sulla modifica del nome utente degli indirizzi email.


(10) Che significa 'UIDPLUS non supportato'?

Il messaggio di errore UIDPLUS non supportato significa che il tuo fornitore email non fornisce l'estensione UIDPLUS di IMAP. Quest'estensione di IMAP è necessaria per implementare la sincronizzazione a due passaggi, che non è una funzionalità opzionale. Quindi, a meno che il tuo fornitore non possa abilitare tale estensione, non puoi usare FairEmail per questo fornitore.


(11) Perché POP non è supportato?

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) Come funziona la crittografia/decrittografia?

Generale

Sei pregato di vedere qui su come funziona la crittografia a chiave pubblica/privata.

Crittografia in breve:

  • I messaggi in uscita sono crittografati con la chiave pubblica del destinatario
  • I messaggi in arrivo sono decrittografati con la chiave privata del destinatario

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

Per firmare/crittografare un messaggio, seleziona semplicemente il metodo appropriato nella finestra di invio. Puoi sempre aprire la finestra di invio usando il menu di overflow a tre puntini nel caso tu abbia prima selezionato Non mostrare più.

Per verificare una firma o decrittografare un messaggio ricevuto, aprilo e tocca semplicemente l'icona del gesto o del lucchetto proprio sotto la barra d'azione del messaggio.

La prima volta che invii un messaggio crittografato/decrittografato, potrebbe essere richiesta una chiave di firma. FairEmail memorizzerà automaticamente la chiave di firma selezionata nell'identità usata per la prossima volta. Se devi ripristinare la chiave di firma, salva semplicemente l'identità o tieni premuta l'identità nell'elenco di identità e seleziona Ripristina tasto di firma. La chiave di firma selezionata è visibile nell'elenco di identità. Se devi selezionare un tasto su base caso per caso, puoi creare identità multiple per lo stesso profilo con lo stesso indirizzo email.

Nelle impostazioni sulla privacy puoi selezionare il metodo di crittografia predefinito (PGP o S/MIME), abilitare Firma di default, Crittografa di default e Decrittografa automaticamente i messaggi, ma sappi che la decrittografia automatica è impossibile se l'interazione dell'utente è necessaria, come la selezione di una chiave o lettura di un token di sicurezza.

Il messaggio di testo/gli allegati da crittografare e il messaggio di testo/allegato decrittografato sono memorizzati solo localmente e non saranno mai aggiunti al server remoto. Se vuoi annullare la decrittografia, puoi usare l'elemento del menu resync nel menu a tre puntini della barra d'azione del messaggio.

PGP

Prima dovrai installare e configurare OpenKeychain. FairEmail è stato testato con la versione 5.4 di OpenKeychain. Le ultime versioni saranno molto probabilmente compatibili, ma le precedenti potrebbero non esserlo.

Importante: l'app di OpenKeychain è nota per crashare (improvvisamente) quando l'app chiamante (FairEmail) non è ancora autorizzata e sta ottenendo una chiave pubblica esistente. Puoi aggirarlo provando ad inviare un messaggio firmato/crittografato ad un mittente con una chiave pubblica sconosciuta.

Importante: se l'app di OpenKeychain non può trovare (più) una chiave, potresti dover ripristinare una chiave precedentemente selezionata. Questo si può fare tenendo premuta un'identità nell'elenco delle identità (Configurazione, passo 2, Gestisci).

Importante: per far connettere affidabilmente le app come FairEmail al servizio di OpenKeychain per crittografare/decrittografare i messaggi, potrebbe essere necessario disabilitare le ottimizzazioni della batteria per l'app di OpenKeychain.

Importante: l'app di OpenKeychain ha bisogno del permesso dei contatti per funzionare correttamente.

<strong x-id"1">Importante: su alcune versioni e dispositivi di Android è necessario abilitare Mostra i popup durante l'esecuzione in background nei permessi aggiuntivi delle impostazioni dell'app di OpenKeychain. Senza questo permesso la bozza sarà salvata, ma il popup di OpenKeychain per confermare/selezionare potrebbe non comparire.

FairEmail invierà l'intestazione di Autocrypt per l'uso da altri clienti di posta elettronica, ma solo per i messaggi firmati e crittografati perché troppi server di email hanno problemi con l'intestazione spesso lunga di Autocrypt. Nota che il modo più sicuro per avviare lo scambio di email crittografate è inviando i messaggi firmati prima. Le intestazioni ricevute di Autocrypt saranno inviate all'app di OpenKeychain per la memorizzazione alla verifica di una firma o decrittografia di un messaggio.

Tutta le gestione delle chiavi è delegata all'app OpenKeychain per motivi di sicurezza. Questo significa anche che FairEmail non memorizza le chiavi PGP.

Il PGP crittografato in linea nei messaggi ricevuti è supportato, ma le firme PGP in linea e il PGP in linea nei messaggi in uscita non sono supportati, vedi qui sul perché non lo sono.

I messaggi di sola firma o sola crittografia non sono una buona idea, sei pregato di vedere qui perché non lo sono:

I messaggi solo firmati sono supportati, i messaggi di sola crittografia no.

Errori comuni:

  • Nessuna chiave: non c'è nessuna chiave PGP disponibile per uno degli indirizzi e-mail elencati
  • Chiave mancante per la crittografia: c'è probabilmente una chiave selezionata in FairEmail che non esiste più nell'applicazione OpenKeychain. Resettare la chiave (vedi sopra) probabilmente risolverà questo problema.

S/MIME

Crittografare un messaggio richiede le chiavi pubbliche dei destinatari. Firmare un messaggio richiede una chiave privata.

Le chiavi private sono memorizzate da Android e sono importabili tramite le impostazioni di sicurezza avanzate di Android. Esiste una scorciatoia (pulsante) per questo nelle impostazioni della privacy. Android ti chiederà di impostare un PIN, uno schema o una password se non lo hai fatto prima. Se hai un dispositivo Nokia con Android 9, sei pregato di leggere questo prima.

Nota che i certificati possono contenere chiavi multiple per scopi multipli, per esempio per l'autenticazione, la crittografia e la firma. Android importa solo la prima chiave, quindi per importarle tutte, il certificato deve prima essere diviso. Questo non è molto banale e ti è consigliato di chiedere supporto al fornitore del certificato.

Nota che la firma S/MIME con altri algoritmi oltre RSA è supportata, ma sappi che altri client di posta elettronica potrebbero non supportarla. La crittografia S/MIME è possibile solo con algoritmi simmetrici, il che significa in pratica usando RSA.

Il metodo di crittografia predefinito è PGP, ma l'ultimo metodo di crittografia usato sarà ricordato per l'identità selezionata la volta successiva. Potresti dover abilitare di nuovo le opzioni di invio nel menu a tre puntini per poter selezionare il metodo di crittografia.

Per consentire le differenti chiavi private per lo stesso indirizzo email, FairEmail ti farà sempre selezionare una chiave quando esistono identità multiple con lo stesso indirizzo email per lo stesso profilo.

Le chiavi pubbliche sono memorizzate da FairEmail e sono importabili quando si verifica una firma per la prima volta o tramite le impostazioni di privacy (formato PEM o DER).

FairEmail verifica sia la firma che la catena di certificati completa.

Errori comuni:

  • 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

Nel caso in cui la catena del certificato sia scorretta, puoi toccare sul piccolo pulsante delle informazioni per mostrare tutti i certificati. 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. Se stai cercando un certificato S/MIME a buon mercato, ho avuto una buona esperienza con 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.

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


(13) Come funziona la ricerca su dispositivo/server?

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) Come configuro un profilo di Outlook / Live / Hotmail?

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) Perché il testo del messaggio continua a caricare?

The message header and message body are fetched separately from the server. Il testo del messaggio di messaggi più grandi non viene pre-recuperato su connessioni misurate e sarà recuperato su domanda all'espansione di un messaggio. 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).

Se FairEmail si sta bloccando a causa di problemi di connettività pregressa, sei pregato di vedere questa FAQ, puoi forzare la sincronizzazione tramite il menu a tre puntini.

Nelle impostazioni di ricezione puoi impostare la dimensione massima per scaricare automaticamente i messaggi su connessioni misurate.

Le connessioni mobili sono quasi sempre misurate e anche alcuni hotspot Wi-Fi (pagati).


(16) Perché i messaggi non sono sincronizzati?

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 4) reduces the chance Android will stop the synchronization service.


(17) Perché la sincronizzazione manuale non funziona?

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

See the previous question for more information.


(18) Perché l'anteprima del messaggio non è sempre mostrata?

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


(19) Perché le funzioni pro sono così costose?

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.

Note that only some convenience and advanced features need to be purchased which means that FairEmail is basically free to use.

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.

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) Posso ottenere un rimborso?

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) Come abilito la luce di notifica?

Before Android 8 Oreo: there is an advanced option in the setup for this.

Android 8 Oreo and later: see here about how to configure notification channels. You can use the button Manage notifications in the setup to directly go to the Android notification settings. Note that apps cannot change notification settings, including the notification light setting, on Android 8 Oreo and later anymore. Apps designed and targeting older Android versions might still be able to control the contents of notifications, but such apps cannot be updated anymore and recent Android versions will show a warning that such apps are outdated.

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 a bug 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) Cosa significa l'errore ... profilo/cartella?

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.

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.

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 setup 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.

L'errore ... Impossibile connettersi all'host ... significa che non c'è stata risposta dal server di email entro un tempo ragionevole (20 secondi di default). Principalmente indica problemi di connettività ad internet, possibilmente causati da un VPN o da un'app firewall. Puoi provare ad aumentare il timeout di connessione nelle impostazioni di connessione di FairEmail, per quando il server dell'email è molto lento.

The error *... Connessione rifiutata... * significa che il server email o qualcosa tra il server dell'email e l'app, come un firewall, ha attivamente rifiutato la connessione.

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 ... or "... Unable to resolve host ... means that the address of the email server could not be resolved. This might be caused by ad blocking or an unreachable or not properly working 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 by peer ... mean that the email server 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 ... 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.

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 Errore di sintassi – linea troppo lunga è spesso causata dall'utilizzo di una lunga intestazione Autocrypt
  • 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 ... non è consentito trasmettere significa che il server di posta elettronica non riconosce il nome utente/indirizzo email. Si prega di controllare il nome host e il nome utente/indirizzo email nelle impostazioni di identità.

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.

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 on refresh ... means that the Android account manager failed to refresh the authorization of a Gmail account.

The error ... Authentication failed ... Invalid credentials ... 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 having revoked the required account/contacts permissions. Just start the wizard (but do not select an account) to grant the required permissions 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) Perché ricevo l'avviso ... ?

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)

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.


(24) Cos'è naviga messaggi sul 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) Perché non posso selezionare/aprire/salvare un'immagine, un allegato o un 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) Posso aiutare a tradurre FairEmail nella mia lingua?

Sì, puoi tradurre i testi di FairEmail nella tua lingua su 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) Come posso distinguere tra le immagini integrate e quelle esterne?

External image:

External image

Embedded image:

Embedded image

Broken image:

Broken image

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) Come posso gestire le notifiche della barra di stato?

In the setup 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) Come posso ottenere le notifiche del nuovo messaggio per le altre cartelle?

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) Come posso usare le impostazioni rapide fornite?

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) Come posso usare le scorciatoie fornite?

There are shortcuts available to:

  • compose a new message to a favorite contact
  • setup accounts, identities, etc

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


(32) Come posso controllare se la lettura dell'email è davvero sicura?

You can use the Email Privacy Tester for this.


(33) Perché gli indirizzi modificati del mittente non funzionano?

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) Come sono abbinate le identità?

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.

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 account color. Setting identity colors is a pro feature.


(35) Perché dovrei fare attenzione visualizzando immagini, allegati e il messaggio originale?

Viewing remotely stored images (see also this FAQ) might not only tell the sender that you have seen the message, but will also leak your IP address.

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) Come sono crittografati i file delle impostazioni?

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) Come sono memorizzate le password?

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) Come posso ridurre l'uso della batteria di 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 let me know.

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. In this case 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 remotes messages are expensive operations.

On some devices it is necessary to disable battery optimizations (setup step 4) to keep connections to email servers open.

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 for, but leave the number of days to keep messages for.

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 4 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) Come posso ridurre l'uso dei dati di 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 for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).

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) Come posso risolvere l'errore 'Negoziazione fallita'?

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) Puoi aggiungere un nuovo fornitore all'elenco di fornitori?

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) Puoi mostrare l'originale di ...?

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) Puoi mostrare le foto / gli identicon nella cartella inviati?

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) Come posso risolvere 'Questa chiave non è disponibile. 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) Perché l'elenco di messaggi continua ad aggiornarsi?

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 for determine how long synchronization will take. Note that you shouldn't set the number of days to synchronize messages for to more than one day in most cases, see also this FAQ.


(47) Come risolvo l'errore 'Nessun profilo principale o nessuna cartella di bozze' ?

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) Come risolvo l'errore "Nessun profilo principale o nessuna cartella d'archivio' ?

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) Come risolvo 'Un'app obsoleta ha inviato un percorso del file invece di un flusso di file' ?

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) Puoi aggiungere un'opzione per sincronizzare tutti i messaggi?

A synchronize all (download all) messages will not be added because it can easily result in out of memory errors and the available storage space filling up. It can also easily result in a lot of battery and data usage. Mobile devices are just not very suitable to download and store years of messages. You can better use the search on server function (see question 13), which is faster and more efficient. Note that searching through a lot of messages stored locally would only delay searching and use extra battery power.


(51) Come sono ordinate le cartelle?

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 setup can be used to manually order the folders.


(52) Perché ci vuole del tempo per riconnettersi ad un profilo?

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) Puoi attaccare la barra d'azione del messaggio in alto/in basso?

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) Come uso il prefisso di uno spazio del nome?

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) Come posso contrassegnare tutti i messaggi come letti / spostati o eliminare tutti i messaggi?

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) Puoi aggiungere il supporto per 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) Posso usare l'HTML nelle firme?

Yes, you can use HTML in signatures if you paste formatted text into the signature field or use the Edit as HTML menu to enter HTML manually.

Note that including links and images in messages will increase the likelihood that a message will be seen as spam, especially when you send a message to someone for the first time.

See here for which HTML tags are supported.


(58) Cosa significa l'icona dell'email aperta/chiusa?

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

External image

Message bodies and attachments are not downloaded by default.

External image

Message bodies and attachments are downloaded by default.


(59) I messaggi originali sono apribili nel 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) Sapevi che ... ?

  • 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?

(61) Perché alcuni messaggi sono mostrati oscurati?

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) Quali metodi di autenticazione sono supportati?

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

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

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.

Server Name Indication is supported by all supported Android versions.


(63) Come sono ridimensionate le immagini per la visualizzazione sugli schermi?

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) Puoi aggiungere azioni personalizzate per lo scorrimento verso sinistra/destra?

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) Perché alcuni allegati sono mostrati oscurati?

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) FairEmail è disponibile nella Libreria di Famiglia di Google Play?

The price of FairEmail is too low, lower than that of most similar apps, and there are too many fees and taxes, Google alone already takes 30 %, to justify making FairEmail available in the Google Play Family Library. Note that Google promotes the Family libray, but lets developers pay for it and doesn't contribute anything.


(67) Come posso posticipare le conversazioni?

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 timelapse 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.

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.


(68) Perché Adobe Acrobat reader non apre gli allegati PDF / le app di Microsoft non aprono i documenti allegati?

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) Puoi aggiungere lo scorrimento automatico in su su un nuovo messaggio?

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) Quando i messaggi saranno espansi automaticamente?

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 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) Come uso le regole del filtro?

You can edit filter rules by long pressing a folder in the folder list.

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
  • Recipient contains
  • Subject contains
  • Has attachments
  • Header contains
  • Day/time 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.

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

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) Cosa sono i profili/le identità primari?

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) Spostare i messaggi tra i profili è sicuro/efficiente?

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) Perché vedo i messaggi duplicati?

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) Puoi fare una versione per iOS, Windows, Linux, etc.?

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) Cosa fa 'Elimina messaggi locali'?

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) Perché a volte i messaggi sono mostrati con un piccolo ritardo?

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) Come uso le pianificazioni?

In the receive settings you can enable scheduling and set the time period and the day of weeks 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.

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 startservice -a eu.faircode.email.POLL

For a specific account:

(adb shell) am startservice -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 startservice -a eu.faircode.email.ENABLE
(adb shell) am startservice -a eu.faircode.email.DISABLE

To enable/disable a specific account:

(adb shell) am startservice -a eu.faircode.email.ENABLE --es account Gmail
(adb shell) am startservice -a eu.faircode.email.DISABLE --es account Gmail

Note that disabling an account will hide the account and all associated folders and 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.

Automation 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 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 no internet connection, for example when flying.

Scheduling is a pro feature.


(79) Come uso sincronizza su domanda (manuale)?

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) Come risolvo l'errore 'Impossibile caricare 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) Puoi rendere scuro lo sfondo del messaggio originale nel tema scuro?

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) Cos'è un'immagine di monitoraggio?

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:

External image

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


(84) A che servono i contatti locali?

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) Perché un'identità non è disponibile?

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) Cosa sono le 'funzionalità di privacy extra'?

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) Cosa significa 'credenziali non valide'?

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) Come posso usare un profilo di Yahoo, AOL o Sky?

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) Come posso inviare messaggi di solo testo semplice?

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) Perché alcuni testi sono collegati senza essere un collegamento?

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.

(91) Puoi aggiungere la sincronizzazione periodica per risparmiare energia della batteria?

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) Puoi aggiungere il filtraggio degli spam, la verifica della firma DKIM e l'autoirzzazione SPF?

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.

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 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 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) Puoi consentire l'installazione/archiviazione dei dati sul media di archiviazione esterna (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) Cosa significa la striscia rossa/arancia alla fine dell'intestazione?

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) Perché non tutte le app sono mostrate selezionando un allegato o immagine?

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) Dove posso trovare le impostazioni IMAP e SMTP?

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


(97) Cos'è una 'pulizia'?

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) Perché posso ancora selezionare i contatti dopo aver revocato i permessi dei contatti?

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) Puoi aggiungere un editor del testo ricco o del markdown?

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) Come posso sincronizzare le categorie di Gmail?

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) Cosa significa il puntino blu/arancio in fondo alle conversazioni?

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) Come posso abilitare la rotazione automatica delle immagini?

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.


(103) Come registro l'audio?

You can record audio if you have a recording app installed which supports the RECORD_SOUND_ACTION intent. If no supported app is installed, FairEmail will not show a record audio action/icon.

Unfortunately and surprisingly, most recording apps do not seem to support this intent (they should).


(104) Cosa devo sapere sulla segnalazione degli errori?

  • 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) Come funziona la funzione roam-like-at-home?

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) Quali launcher possono mostrare un distintivo di conteggio con il numero di messaggi non letti?

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

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 or disabled.

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 '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 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.

Note that Tesla Unread is not supported anymore.

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) Come uso le stelle colorate?

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) Puoi aggiungere l'eliminazione permanente dei messaggi da ogni cartella?

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) Perché 'seleziona profilo' è disponibile solo nelle versioni ufficiali?

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) Perché (alcuni) messaggi sono vuoti e/o gli allegati sono danneggiati?

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:

Setup > Step 1 > Manage > 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) OAuth è supportato?

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.

OAuth for Yandex is supported via the quick setup wizard.

OAuth for Office 365 accounts is supported, but Microsoft does not offer OAuth for Outlook, Live and Hotmail accounts (yet?).

OAuth access for Yahoo was requested, but Yahoo never responded to the request. OAuth for AOL was deactivated by AOL. Verizon owns both AOL and Yahoo, collectively named Oath inc. So, it is reasonable to assume that OAuth is not supported by Yahoo anymore too.


(112) Quale fornitore di email raccomandi?

FairEmail is an email client only, so you need to bring your own email address.

There are plenty of email providers to choose from. Which email provider is best for you depends on your wishes/requirements. Please see the websites of Restore privacy or Privacy Tools for a list of privacy oriented email providers with advantages and disadvantages.

Some providers, like ProtonMail, Tutanota, use proprietary email protocols, which make it impossible to use third party email apps. Please see this FAQ for more information.

Using your own (custom) domain name, which is supported by most email providers, will make it easier to switch to another email provider.


(113) Come funziona l'autenticazione biometrica?

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 setup 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) Puoi aggiungere un'importazione per le impostazioni di altre app di email?

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 for and for the number of days to keep messages for, mainly to save on battery usage. Moreover, setting up an account/identity with the quick setup is simple, so it is not really worth the effort.


(115) Puoi aggiungere i chip dell'indirizzo email?

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) Come posso mostrare le immagini nei messaggi da mittenti fidati di 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) Puoi aiutarmi a ripristinare il mio acquisto?

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
  • 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

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:

  • 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) Cosa fa esattamente 'Rimuovi parametri di monitoraggio'?

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


(119) Puoi aggiungere i colori al widget di posta in arrivo unificato?

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) Perché le notifiche di nuovi messaggi non sono rimosse all'apertura dell'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) Come sono raggruppati i messaggi in una conversazione?

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) Perché il nome/l'indirizzo email del destinatario è mostrato con un colore di avviso?

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) Cosa succederà quando FairEmail non potrà connettersi ad un server email?

When FairEmail cannot connect to an email server to receive messages, for example when the internet connection is bad or a firewall or a VPN is blocking the connection, FairEmail will wait 8, 16 and 32 seconds while keeping the device awake (=use battery power) and try again to connect. If this fails, FairEmail will schedule an alarm to retry after 15, 30 and 60 minutes and let the device sleep (=no battery usage).

Between connectivity changes there is a wait of 90 seconds to give the email server the opportunity to discover the old connection is broken. This is necessary because the internet connection of a mobile device is often lost abruptly and to prevent the problem described in this FAQ.

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 open/expand the message and use the undo icon to move the message to the drafts folder, possible change it and send it again.


(124) Perché ottengo 'Messaggio troppo grande o troppo complesso da mostrare'?

The message Message too large or too complex to display will be shown if there are more than 100,000 characters or more than 500 links in a message. Reformatting and displaying such messages will take too long. You can try to use the original message view, powered by the browser, instead.


(125) Quali sono le funzionalità sperimentali attuali?

  • ...

(126) Le anteprime dei messaggi possono essere inviate al mio indossabile?

FairEmail fetches a message in two steps:

  1. Fetch message headers
  2. Fetch message text and attachments

Directly after the first step new messages will be notified. However, only until after the second step the message text will be available. FairEmail updates exiting notifications with a preview of the message text, but unfortunately wearable notifications cannot be updated.

Since there is no guarantee that a message text will always be fetched directly after a message header, it is not possible to guarantee that a new message notification with a preview text will always be sent to a wearable.

If you think this is good enough, you can enable the notification option Only send notifications with a message preview to wearables and if this does not work, you can try to enable the notification option Show notifications with a preview text only.

If you want to have the full message text sent to your wearable, you can enable the notification option Preview all text. Note that some wearables are known to crash with this option enabled.

If you use a Samsung wearable with the Galaxy Wearable (Samsung Gear) app, you might need to enable notifications for FairEmail when the setting Notifications, Apps installed in the future is turned off in this app.


(127) Come posso risolvere 'Argomenti HELO sintatticamente non validi'?

The error ... Syntactically invalid HELO argument(s) ... means that the SMTP server rejected the local IP address or host name. You can likely fix this error by enabling or disabling the advanced indentity option Use local IP address instead of host name.


(128) Come posso ripristinare le domande chieste, per esempio per mostrare le immagini?

You can reset asked questions via the three dots overflow menu in the miscellaneous settings.


(129) ProtonMail e Tutanota sono supportati?

ProtonMail uses a proprietary email protocol and does not directly support IMAP, so you cannot use FairEmail to access ProtonMail.

Tutanota uses a proprietary email protocol and does not support IMAP, so you cannot use FairEmail to access Tutanota.


(130) Cosa significa il messaggio errore ...?

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) Puoi modificare la direzione per lo scorrimento al messaggio precedente/successivo?

If you read from left to right, swiping to the left will show the next message. Similarly, if you read from right to left, swiping to the right will show the next message.

This behavior seems quite natural to me, also because it is similar to turning pages.

Anyway, there is a behavior setting to reverse the swipe direction.


(132) Perché le notifiche dei messaggi sono silenziate?

Notifications are silent by default on some MIUI versions. Please see here how you can fix this.

There is a bug in some Android versions causing setOnlyAlertOnce to mute notifications. Since FairEmail shows new message notifications right after fetching the message headers and FairEmail needs to update new message notifications after fetching the message text later, this cannot be fixed or worked around by FairEmail.

Android might rate limit the notification sound, which can cause some new message notifications to be silent.


(133) Perché ActiveSync non è supportato?

The Microsoft Exchange ActiveSync protocol is patented and can therefore not be supported. For this reason you won't find many, if any, other email clients supporting ActiveSync.

The Microsoft Exchange Web Services protocol is being phased out.

Note that the desciption of FairEmail starts with the remark that non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync are not supported.


(134) Puoi aggiungere l'eliminazione dei messaggi locali?

POP3

In the account settings (Setup, step 1, Manage, tap account) you can enable Leave deleted messages on server.

IMAP

Since the IMAP protocol is meant to synchronize two ways, deleting a message from the device would result in fetching the message again when synchronizing again.

However, FairEmail supports hiding messages, either via the three-dots menu in the action bar just above the message text or by multiple selecting messages in the message list. Basically this is the same as "leave on server" of the POP3 protocol with the advantage that you can show the messages again when needed.

Note that it is possible to set the swipe left or right action to hide a message.


(135) Perché i messaggi cestinati e le bozze sono mostrati nelle conversazioni?

Individual messages will rarely be trashed and mostly this happens by accident. Showing trashed messages in conversations makes it easier to find them back.

You can permanently delete a message using the message three-dots delete menu, which will remove the message from the conversation. Note that this irreversible.

Similarly, drafts are shown in conversations to find them back in the context where they belong. It is easy to read through the received messages before continuing to write the draft later.


(136) Come posso eliminare un profilo/identità/cartella?

Deleting an account/identity/folder is a little bit hidden to prevent accidents.

  • Account: Setup > Step 1 > Manage > Tap account
  • Identity: Setup > Step 2 > Manage > Tap identity
  • Folder: Long press the folder in the folder list > Edit properties

In the three-dots overflow menu at the top right there is an item to delete the account/identity/folder.


(137) Come posso ripristinare 'Non chiedere più'?

You can reset all questions set to be not asked again in the miscellaneous settings.


(138) Puoi aggiungere il calendario/la gestione dei contatti/la sincronizzazione?

Calendar and contact management can better be done by a separate, specialized app. Note that FairEmail is a specialized email app, not an office suite.

Also, I prefer to do a few things very well, instead of many things only half. Moreover, from a security perspective, it is not a good idea to grant many permissions to a single app.

You are advised to use the excellent, open source DAVx⁵ app to synchronize/manage your calendars/contacts.

Most providers support exporting your contacts. Please see here about how you can import contacts if synchronizing is not possible.

Note that FairEmail does support replying to calendar invites (a pro feature) and adding calendar invites to your personal calendar.


(139) Come risolvo 'L'utente è autenticato ma non connesso'?

In fact this Microsoft Exchange specific error is an incorrect error message caused by a bug in older Exchange server software.

The error User is authenticated but not connected might occur if:

  • Push messages are enabled for too many folders: see this FAQ for more information and a workaround
  • The account password was changed: changing it in FairEmail too should fix the problem
  • An alias email address is being used as username instead of the primary email address
  • An incorrect login scheme is being used for a shared mailbox: the right scheme is username@domain\SharedMailboxAlias

The shared mailbox alias will mostly be the email address of the shared account, like this:

you@example.com\shared@example.com

Note that it should be a backslash and not a forward slash.


(140) Perché il testo del messaggio contiene caratteri strani?

Displaying strange characters is almost always caused by specifying no or an invalid character encoding by the sending software. FairEmail will assume ISO 8859-1 when no character set or when US-ASCII was specified. Other than that there is no way to reliably determine the correct character encoding automatically, so this cannot be fixed by FairEmail. The right action is to complain to the sender.


(141) Come posso risolvere 'Una cartella delle bozze è necessaria per inviare i messaggi'?

To store draft messages a drafts folder is required. In most cases FairEmail will automatically select the drafts folders on adding an account based on the attributes the email server sends. However, some email servers are not configured properly and do not send these attributes. In this case FairEmail tries to identify the drafts folder by name, but this might fail if the drafts folder has an unusual name or is not present at all.

You can fix this problem by manually selecting the drafts folder in the account settings (Setup, step 1, tap account, at the bottom). If there is no drafts folder at all, you can create a drafts folder by tapping on the '+' button in the folder list of the account (tap on the account name in the navigation menu).

Some providers, like Gmail, allow enabling/disabling IMAP for individual folders. So, if a folder is not visible, you might need to enable IMAP for the folder.

Quick link for Gmail: https://mail.google.com/mail/u/0/#settings/labels


(142) Come posso memorizzare i messaggi inviati nella posta in arrivo?

Generally, it is not a good idea to store sent messages in the inbox because this is hard to undo and could be incompatible with other email clients.

That said, FairEmail is able to properly handle sent messages in the inbox. FairEmail will mark outgoing messages with a sent messages icon for example.

The best solution would be to enable showing the sent folder in the unified inbox by long pressing the sent folder in the folder list and enabling Show in unified inbox. This way all messages can stay where they belong, while allowing to see both incoming and outgoing messages at one place.

If this is not an option, you can create a rule to automatically move sent messages to the inbox or set a default CC/BCC address in the advanced identity settings to send yourself a copy.


(143) Puoi aggiungere una cartella del cestino per i profili POP3?

POP3 is a very limited protocol. Basically only messages can be downloaded and deleted from the inbox. It is not even possible to mark a message read.

Since POP3 does not allow access to the trash folder at all, there is no way to restore trashed messages.

Note that you can hide messages and search for hidden messages, which is similar to a local trash folder, without suggesting that trashed messages can be restored, while this is actually not possible.

Version 1.1082 added a local trash folder. Note that trashing a message will permanently remove it from the server and that trashed messages cannot be restored to the server anymore.


(144) Come posso registrare le note vocali?

To record voice notes you can press this icon in the bottom action bar of the message composer:

External image

This requires a compatible audio recorder app to be installed. In particular this common intent needs to be supported.

For example this audio recorder is compatible.

Voice notes will automatically be attached.


(145) Come posso impostare un suono di notifica per un profilo, cartella o mittente?

Account:

  • Enable Separate notifications in the advanced account settings (Setup, step 1, Manage, tap account, tap Advanced)
  • Long press the account in the account list (Setup, step 1, Manage) and select Edit notification channel to change the notification sound

Folder:

  • Long press the folder in the folder list and select Create notification channel
  • Long press the folder in the folder list and select Edit notification channel to change the notification sound

Sender:

  • Open a message from the sender and expand it
  • Expand the addresses section by tapping on the down arrow
  • Tap on the bell icon to create or edit a notification channel and to change the notification sound

The order of precendence is: sender sound, folder sound, account sound and default sound.

Setting a notification sound for an account, folder or sender requires Android 8 Oreo or later and is a pro feature.


(146) Come posso risolvere gli orari scorretti del messaggio?

Since the sent date/time is optional and can be manipulated by the sender, FairEmail uses the server received date/time by default.

Sometimes the server received date/time is incorrect, mostly because messages were incorrectly imported from another server and sometimes due to a bug in the email server.

In these rare cases, it is possible to let FairEmail use either the date/time from the Date header (sent time) or from the Received header as a workaround. This can be changed in the advanced account settings: Setup, step 1, Manage, tap account, tap Advanced.

This will not change the time of already synchronized messages. To solve this, long press the folder(s) in the folder list and select Delete local messages and Synchronize now.


(147) Cosa dovrei sapere sulle versioni di terze parti?

You likely came here because you are using a third party build of FairEmail.

There is only support on the latest Play store version, the latest GitHub release and the F-Droid build, but only if the version number of the F-Droid build is the same as the version number of the latest GitHub release.

F-Droid builds irregularly, which can be problematic when there is an important update. Therefore you are advised to switch to the GitHub release.

The F-Droid version is built from the same source code, but signed differently. This means that all features are available in the F-Droid version too, except for using the Gmail quick setup wizard because Google approved (and allows) one signature only.

Note that you'll need to uninstall the F-Droid build first before you can install a GitHub release because Android refuses to install the same app with a different signature for security reasons.

Note that the GitHub version will automatically check for updates. When desired, this can be turned off in the miscellaneous settings.

Please see here for all download options.

If you have a problem with the F-Droid build, please check if there is a newer GitHub version first.


(148) Come posso usare un profilo di Apple iCloud?

There is a built-in profile for Apple iCloud, but if needed you can find the right settings here.

When using two-factor authentication you might need to use an app-specific password.


(149) Come funziona il widget di conteggio dei messaggi non letti?

The unread message count widget shows the number of unread messages either for all accounts or for a selected account, but only for the folders for which new message notifications are enabled.

Tapping on the notification will synchronize all folders for which synchronization is enabled and will open:

  • the start screen when all accounts were selected
  • a folder list when a specific account was selected and when new message notifications are enabled for multiple folders
  • a list of messages when a specific account was selected and when new message notifications are enabled for one folder

(150) Puoi aggiungere l'annullamento degli inviti del calendario?

Cancelling calendar invites (removing calendar events) requires write calendar permission, which will result in effectively granting permission to read and write all calendar events of all calendars.

Given the goal of FairEmail, privacy and security, and given that it is easy to remove a calendar event manually, it is not a good idea to request this permission for just this reason.

Inserting new calendar events can be done without permissions with special intents. Unfortunately, there exists no intent to delete existing calendar events.


(151) Puoi aggiungere il backup/ripristino dei messaggi?

An email client is meant to read and write messages, not to backup and restore messages. Note that breaking or losing your device, means losing your messages!

Instead, the email provider/server is responsible for backups.

If you want to make a backup yourself, you could use a tool like imapsync.

If you want to import an mbox file to an existing email account, you can use Thunderbird on a desktop computer and the ImportExportTools add-on.


(152) Come posso inserire un gruppo di contatto?

You can insert the email addresses of all contacts in a contact group via the three dots menu of the message composer.

You can define contact groups with the Android contacts app, please see here for instructions.


(153) Perché non funziona l'eliminazione permanente del messaggio di Gmail?

You might need to change the Gmail IMAP settings on a desktop browser to make it work:

  • When I mark a message in IMAP as deleted: Auto-Expunge off - Wait for the client to update the server.
  • When a message is marked as deleted and expunged from the last visible IMAP folder: Immediately delete the message forever

Note that archived messages can be deleted only by moving them to the trash folder first.

Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view.


(154) Puoi aggiungere i favicon come foto di contatto?

Besides that a favicon might be shared by many email addresses with the same domain name and therefore is not directly related to an email address, favicons can be used to track you.


(155) Cos'è un file winmail.dat?

A winmail.dat file is sent by an incorrectly configured Outlook client. It is a Microsoft specific file format (TNEF) containing a message and possibly attachments.

You can find some more information about this file here.

You can view it with for example the Android app Letter Opener.


(156) Come posso configurare un profilo di Office 365?

An Office 365 account can be set up via the quick setup wizard and selecting Office 365 (OAuth).

If the wizard ends with AUTHENTICATE failed, IMAP and/or SMTP might be disabled for the account. In this case you should ask the administrator to enable IMAP and SMTP. The procedure is documented here.

If you've enabled security defaults in your organization, you might need to enable the SMTP AUTH protocol. Please see here about how to.


(157) How can I set up an Free.fr account?

Veuillez voir ici pour les instructions.

SMTP est désactivé par défaut, veuillez voir ici comment il peut être activé.

Veuillez voir ici pour un guide détaillé.


(158) Which camera / audio recorder do you recommend?

To take photos and to record audio a camera and an audio recorder app are needed. The following apps are open source cameras and audio recorders:

To record voice notes, etc, the audio recorder needs to support MediaStore.Audio.Media.RECORD_SOUND_ACTION. Oddly, most audio recorders seem not to support this standard Android action.


(159) What are Disconnect's tracker protection lists?

Please see here for more information about Disconnect's tracker protection lists.

After downloading the lists in the privacy settings, the lists can optionally be used:

  • to warn about tracking links on opening links
  • to recognize tracking images in messages

Tracking images will be disabled only if the corresponding main 'disable' option is enabled.

Tracking images will not be recognized when the domain is classified as 'Content', see here for more information.

This command can be sent to FairEmail from an automation app to update the protection lists:

(adb shell) am startservice -a eu.faircode.email.DISCONNECT.ME

Updating once a week will probably be sufficient, please see here for recent lists changes.


(160) Can you add permanent deletion of messages without confirmation?

Permanent deletion means that messages will irreversibly be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(


(161) Can you add a setting to change the primary and accent color?*

If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example here, so this is not possible.


Supporto

Only the latest Play store version and latest GitHub release are supported. This also means that downgrading is not supported.

Requested features should:

  • be useful to most people
  • not complicate the usage of FairEmail
  • fit within the philosophy of FairEmail (privacy oriented, security minded)
  • comply with common standards (IMAP, SMTP, etc)

Features not fulfilling these requirements will likely be rejected. This is also to keep maintenance and support in the long run feasible.

If you have a question, want to request a feature or report a bug, please use this form.

GitHub issues are disabled due to frequent misusage.
