## Mengizinkan akun
4 years ago
4 years ago
In most cases, the quick setup wizard will be able to automatically identify the correct configuration.
4 years ago
4 years ago
If the quick setup wizard fails, you'll need to manually set up an account (to receive email) and an identity (to send email). Untuk itu, Anda membutuhkan alamat server IMAP dan SMTP dan nomor port, gunakan SSL/TLS atau STARTTLS dan nama pengguna Anda (umumnya, tapi terkadang tidak perlu, alamat surel Anda) dan kata sandi Anda.

Mencari *IMAP* dan nama provider selalu cukup untuk menemukan dokumentasi yang cocok.

Dalam beberapa kasus, Anda perlu mengaktifkan akses eksternal ke akun Anda dan/atau gunakan (aplikasi) kata sandi spesial, misalnya ketika otentikasi dua faktor diaktifkan.

## Kendala yang diketahui
* ~~ [Gangguan pada Android 5.1 and 6](https://issuetracker.google.com/issues/37054851) yang menyebabkan aplikasi menampilkan format waktu yang salah beberapa kali. Mengubah pengaturan Android *Gunakan format waktu 24 jam* dapat menyelesaikan kendala saat ini. Solusi telah ditambahkan.~~
* ~~ [Gangguan pada Google Drive](https://issuetracker.google.com/issues/126362828) menyebabkan berkas yang diekspor ke Google Drive kosong. Google telah memperbaikinya.~~
4 years ago
* ~~[Bug di AndroidX](https://issuetracker.google.com/issues/78495471) menyebabkan FairEmail mengalami kegagalan dalam menekan dengan lama atau menggeser. Google telah memperbaiki ini.~~
* ~~[Bug di AndroidX ROOM](https://issuetracker.google.com/issues/138441698) menyebabkan crash dengan "*... Pengecualian saat meghitung database data langsung ... Tidak dapat membaca barisan ...*". Solusi telah ditambahkan.~~
* [Bug di Android](https://issuetracker.google.com/issues/119872129) menyebabkan FairEmail crash dengan "*... Notifikasi buruk diposkan ...*" dalam beberapa perangkat setelah memperbarui FairEmail dan mengklik notifikasi.
* [Bug di Android](https://issuetracker.google.com/issues/62427912) beberapa kali menyebabkan crash dengan "*... RekamanAktivitas tidak ditemukan untuk ...*" setelah memperbarui FairEmail. Menginstal ulang ([sumber](https://stackoverflow.com/questions/46309428/android-activitythread-reportsizeconfigurations-causes-app-to-freeze-with-black)) dapat memperbaiki masalah.
* [Bug di Android](https://issuetracker.google.com/issues/37018931) beberapa kali menyebabkan crash dengan *... InputChannel is not initialized ...* on some devices.
* [Bug di LineageOS](https://review.lineageos.org/c/LineageOS/android_frameworks_base/+/265273) beberapa kali menyebabkan crash dengan *... java.lang.ArrayIndexOutOfBoundsException: length=...; index=... ...*.~~
* Bug di Nova Launcher dalam Android 5.x menyebabkan FairEmail crash dengan *java.lang.StackOverflowError* ketika Nova Launcher mengakses servis aksesibilitas.
* ~~Pemilih berkas beberpa kali menampilkan tidak ada berkas dengan alasan yang tidak diketahui. Masalah ini terlihat sudah diperbaiki.~~
* ~~[Bug di AndroidX](https://issuetracker.google.com/issues/64729576) menyebabkan kesulitan untuk menekan scroll cepat. Solusi telah ditambahkan.~~
* ~~Enkripsi menggunakan YubiKey mengakibaykan putaran yang terus menerus. Hal ini disebabkan karena sebuah [bug di OpenKeychain](https://github.com/open-keychain/open-keychain/issues/2507).~~
4 years ago
* Scrolling to an internally linked location in original messages does not work. This can't be fixed because the original message view is contained in a scrolling view.
4 years ago
* Tampilan teks pesan tidak (selalu) terlihat pada jam Samsung karena [setLocalOnly](https://developer.android.com/reference/androidx/core/app/NotificationCompat.Builder.html#setLocalOnly(boolean)) sepertinya dihindari. Tampilan teks pesan diketahui dapat ditampilkan dengan benar pada perangkat wearable Pebble 2, Fitbit Charge 3, Mi band 3, dan Xiaomi Amazfit BIP. Lihat juga [FAQ ini](#user-content-faq126).
4 years ago
* [Bug idi Android 6.0](https://issuetracker.google.com/issues/37068143) menyebabkan crash dengan *... Invalid offset: ... Valid range is ...* when text is selected and tapping outside of the selected text. Bug ini telah diperbaiki dalam Android 6.0.1.
* Internal (anchor) links will not work because original messages are shown in an embedded WebView in a scrolling view (the conversation list). Hal ini merupakan limitasi Android yang tidak dapat diperbaiki atau di buat bekerja.

* ~~Salinan pesan~~
4 years ago
* ~~Bintang berwarna~~
4 years ago
* ~~Pengaturan notifikasi per berkas~~

4 years ago
* ~~Tampilkan pesan yang cocok dengan pengaturan~~
4 years ago
* ~~[ManageSieve](https://tools.ietf.org/html/rfc5804)~~ (there are no maintained Java libraries with a suitable license and without dependencies and besides that, FairEmail has its own filter rules)
4 years ago

4 years ago
* ~~Penyaranan pencarian~~
4 years ago
* ~~[Autocrypt Setup Message](https://autocrypt.org/autocrypt-spec-1.0.0.pdf) (section 4.4)~~ (IMO it is not a good idea to let an email client handle sensitive encryption keys for an exceptional use case while OpenKeychain can export keys too)

4 years ago
* ~~Pinch zoom text size~~
4 years ago
* ~~Tampilan GIF~~
* ~~Tema~~ (tema abu-abu muda dan gelap telah ditambahkan karena tema ini yang paling banyak disukai orang)
4 years ago
* ~~Any day time condition~~ (any day doesn't really fit into the from/to date/time condition)
4 years ago
* ~~Kirimkan sebagai lampiran~~
* ~~Widget untuk akun yang dipilih~~
* ~~Pengingat untuk melampirkan berkas~~
4 years ago

4 years ago

Desain ini bersadarkan dari banyak diskusi dan anda dapat mendiskusikannya [di forum ini](https://forum.xda-developers.com/android/apps-games/source-email-t3824168) jika anda menginginkannya. Tujuan dari desain ini adalah minimalis (tidak ada menu, tombol, dll. yang tidak diperlukan) dan tidak mengganggu (tidak ada warna atau animasi yang mencolok, dsb.). Hal-hal yang ditampilkan disini harus berguna sebagaimanapun dan harus ditempatkan secara tepat untuk penggunaan yang mudah. Font, ukuran, warna dan lainnya harus menggunakan desain material bila memungkinkan.

FairEmail akan menyimpan daftar alamat dari pesan yang anda terima dan pesan yang anda kirim, serta akan menggunakan daftar ini untuk penyaranan kontak ketika tidak ada perizinan kontak yang diberikan untuk FairEmail. Artinya, anda dapat menggunakan FairEmail tanpa adanya penyedia kontak Android (buku alamat). Perhatikan bahwa anda masih tetap dapat memilih kontak tanpa anda memberikan izin kontak ke FairEmail, hanya memberikan saran kontak tidak bekerja tanpa mengizinkan kontak.

**(2) mengapa terdapat notifikasi yang permanen yang terlihat?**
4 years ago
4 years ago
Bilah status notifkasi permanen yang berprioritas rendah dengan jumlah akun yang sedang dalam pantauan dan jumlah operasi yang tertunda (lihat pertanyaan selanjutnya) ditampilkan untuk mengindari Android mematikan layanan yang mengerjakan penerimaan surel yang terus menerus. Hal ini [telah menjadi penting](https://developer.android.com/reference/android/app/Service.html#startForeground(int,%20android.app.Notification)), namun dengan adanya pengenalan dari [mode doze](https://developer.android.com/training/monitoring-device-state/doze-standby) dalam Android 6 Marshmallow hal in menjadi lebih penting dibandingkan sebelumnya. Mode doze akan menghentikan seluruh aplikasi ketika layar sedang dalam keadaan mati beberapa saat, kecuali ketika aplikasi telah menjalankan layanan latar depan, yang membutuhkan tampilan bilah status notifikasi.
4 years ago
4 years ago
Kebanyakan, namun tidak semua, aplikasi surel lainnya tidak menampilkan notifikasi dengan "efek samping" yaitu pesan baru akan sering tidak atau terlambat diberitahukan dan pesan tersebut tidak atau terlambat dikirimkan.
4 years ago
4 years ago
Android menampilkan ikon bilah status notifikasi dengan prioritas tinggi terlebih dahulu dan akan menyembunyikan ikon notifikasi FairEmail jika tidak ada tempat untuk menampilkan ikon lagi. Secara praktis, hal ini berarti bilah status notifikasi tidak mengambil tempat di bilah status kecuali memang ada tempat tersedia.
4 years ago
4 years ago
Bilah status notifikasi dapat dinonaktifkan lewat pengaturan notifikasi FairEmail:
4 years ago
4 years ago
* Android 8 Oreo sampai yang terbaru: tekan tombol *Penerimaan channel* dan matikan channel tersebut lewat pengaturan Android (hal ini tidak akan menonaktifkan notifikasi pesan baru)
* Android 7 Nougat dan sebelumnya: aktifkan *Gunakan layanan latar untuk mensingkroniasikan pesan*, namun harap membaca catatan dibawah pengaturan
4 years ago
4 years ago
Anda dapat mengubah ke singkronisasi pesan secara perodik dalam pengaturan penerimaan untuk menghapus notifikasi, namun waspadalah bahwa hal ini dapat menggunakan daya baterai yang lebih banyak. Lihat [di sini](#user-content-faq39) untuk rincian lebih anjut tentang penggunaan baterai.
4 years ago

Android 8 Oreo mungkin akan juga menampilkan bilah status notifikasi dengan tulisan *Aplikasi berjalan di background*. Sila lihat [di sini](https://www.reddit.com/r/Android/comments/7vw7l4/psa_turn_off_background_apps_notification/) tentang bagaimana cara anda untuk mematikan notifikasi ini.
4 years ago
4 years ago
Beberapa orang memberikan saran untuk menggunakan [Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging/) (FCM) dibandingkan layanan Android dengan bilah status notifikasi, namun hal ini membutuhkan surel penyedia untuk mengirimkan pesan FCM atau server pusat di mana seluruh pesan dikumpulkan untuk mengirim pesan FCM. Hal yang pertama tidak akan terjadi dan hal yang kedua akan berdampak ke impikasi privasi yang signifikan.

* *pindah*: memindahkan pesan ke folder remot lainnya
* *salin*: menyalin pesan ke folder remot lainnya
* *ambil*: memperoleh perubahan pesan (push)
* *hapus*: menghapus pesan dari folder remot

**(4) Bagaimana cara saya menggunakan sertifikat keamanan yang tidak valid / kata sandi kosong / koneksi teks kosong?**
4 years ago
*... Untrusted ... not in certificate ...*
<br />
*... Invalid security certificate (Can't verify identity of server) ...*
4 years ago
This can be caused by using an incorrect host name, so first double check the host name in the advanced identity/account settings (tap Manual setup and more options). Please see the documentation of the email provider about the right host name.
4 years ago
4 years ago
You should try to fix this by contacting your provider or by getting a valid security certificate because invalid security certificates are insecure and allow [man-in-the-middle attacks](https://en.wikipedia.org/wiki/Man-in-the-middle_attack). If money is an obstacle, you can get free security certificates from [Lets Encrypt](https://letsencrypt.org).
Alternatively, you can accept the fingerprint of invalid server certificates like this:
4 years ago
4 years ago
1. Pastikan Anda menggunakan koneksi internet tepercaya (tidak di jaringan Wi-Fi publik, dll)
1. Buka layar pengaturan melalui menu navigasi (geser dari sisi kiri ke dalam)
4 years ago
1. Tap Manual setup and more options, tap Accounts/Identities and tap the faulty account and identity
4 years ago
1. Periksa / simpan akun dan identitas
1. Centang kotak di bawah pesan kesalahan dan simpan lagi
4 years ago
This will "pin" the server certificate to prevent man-in-the-middle attacks.
Note that older Android versions might not recognize newer certification authorities like Lets Encrypt causing connections to be considered insecure, see also [here](https://developer.android.com/training/articles/security-ssl).
4 years ago
*Trust anchor for certification path not found*
*... java.security.cert.CertPathValidatorException: Trust anchor for certification path not found ...* means that the default Android trust manager was not able to verify the server certificate chain.
4 years ago
You should either fix the server configuration or accept the fingerprint shown below the error message.
4 years ago
4 years ago
Note that this problem can be caused by the server not sending all intermediate certificates too.
4 years ago

*Empty password*
4 years ago
4 years ago
Your username is likely easily guessed, so this is insecure.
4 years ago
*Plain text connection*
4 years ago
Your username and password and all messages will be sent and received unencrypted, which is **very insecure** because a [man-in-the-middle attack](https://en.wikipedia.org/wiki/Man-in-the-middle_attack) is very simple on an unencrypted connection.
4 years ago
4 years ago
If you still want to use an invalid security certificate, an empty password or a plain text connection you'll need to enable insecure connections in the account and/or identity settings. STARTTLS should be selected for plain text connections. If you enable insecure connections, you should connect via private, trusted networks only and never via public networks, like offered in hotels, airports, etc.

**(6) How can I login to Gmail / G suite?**
4 years ago
4 years ago
If you use the Play store or GitHub version of FairEmail, you can use the quick setup wizard to easily setup a Gmail account and identity. The Gmail quick setup wizard is not available for third party builds, like the F-Droid build because Google approved the use of OAuth for official builds only.
4 years ago
4 years ago
If you don't want to use an on-device Gmail account, you can either enable access for "less secure apps" and use your account password (not advised) or enable two factor authentication and use an app specific password. To use a password you'll need to set up an account and identity via the manual setup instead of via the quick setup wizard.
4 years ago

**(7) Why are sent messages not appearing (directly) in the sent folder?**
4 years ago
4 years ago
Sent messages are normally moved from the outbox to the sent folder as soon as your provider adds sent messages to the sent folder. This requires a sent folder to be selected in the account settings and the sent folder to be set to synchronizing.
4 years ago
4 years ago
Some providers do not keep track of sent messages or the used SMTP server might not be related to the provider. In these cases FairEmail, will automatically add sent messages to the sent folder on synchronizing the sent folder, which will happen after a message have been sent. Note that this will result in extra internet traffic.
4 years ago
4 years ago
~~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.~~
4 years ago
4 years ago
~~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.~~

**~~(10) What does 'UIDPLUS not supported' mean?~~**
~~The error message *UIDPLUS not supported* means that your email provider does not provide the IMAP [UIDPLUS extension](https://tools.ietf.org/html/rfc4315).

**~~(11) Why is POP not supported?~~**
4 years ago
4 years ago
~~Besides that any decent email provider supports [IMAP](https://en.wikipedia.org/wiki/Internet_Message_Access_Protocol) these days,~~ ~~using [POP](https://en.wikipedia.org/wiki/Post_Office_Protocol) 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.~~

**(12) How does encryption/decryption work?**
4 years ago
4 years ago
Communication with email servers is always encrypted, unless you explicitly turned this off. This question is about optional end-to-end encryption with PGP or S/MIME. The sender and recipient should first agree on this and exchange signed messages to transfer their public key to be able to send encrypted messages.
4 years ago
*General*
4 years ago
4 years ago
Please [see here](https://en.wikipedia.org/wiki/Public-key_cryptography) about how public/private key encryption works.
4 years ago
4 years ago
Encryption in short:
4 years ago
4 years ago
* Pesan **keluar** terenkripsi dengan **kunci publik** dari penerima
* Pesan **masuk** terdekripsi dengan **kunci privat** dari penerima
4 years ago
4 years ago
Signing in short:
4 years ago
4 years ago
* Pesan **keluar** tersign dengan **kunci privat** dari pengirim
* Pesan **masuk** diverifikasi dengan **kunci publik** dari pengirim
4 years ago
4 years ago
To sign/encrypt a message, just select the appropriate method in the send dialog. You can always open the send dialog using the three-dots overflow menu in case you selected *Don't show again* before.
4 years ago
4 years ago
To verify a signature or to decrypt a received message, open the message and just tap the gesture or padlock icon just below the message action bar.
4 years ago
4 years ago
The first time you send a signed/encrypted message you might be asked for a sign key. FairEmail will automatically store the selected sign key in the used identity for the next time. If you need to reset the sign key, just save the identity or long press the identity in the list of identities and select *Reset sign key*. The selected sign key is visible in the list of identities. If need to select a key on a case by case basis, you can create multiple identities for the same account with the same email address.
4 years ago
4 years ago
In the privacy settings you can select the default encryption method (PGP or S/MIME), enable *Sign by default*, *Encrypt by default* and *Automatically decrypt messages*, but be aware that automatic decryption is not possible if user interaction is required, like selecting a key or reading a security token.
4 years ago
4 years ago
The to be encrypted message text/attachments and the decrypted message text/attachments are stored locally only and will never be added to the remote server. If you want to undo decryption, you can use the *resync* menu item in the three-dots menu of the message action bar.
4 years ago
*PGP*
You'll need to install and configure [OpenKeychain](https://f-droid.org/en/packages/org.sufficientlysecure.keychain/) first. FairEmail was tested with OpenKeychain version 5.4. Later versions will most likely be compatible, but earlier versions might not be.
**Important**: the OpenKeychain app is known to (silently) crash when the calling app (FairEmail) is not authorized yet and is getting an existing public key. You can workaround this by trying to send a signed/encrypted message to a sender with an unknown public key.
4 years ago
**Important**: if the OpenKeychain app cannot find a key (anymore), you might need to reset a previously selected key. This can be done by long pressing an identity in the list of identities (Settings, tap Manual setup and more options, tap Identities).
4 years ago
**Important**: to let apps like FairEmail reliably connect to the OpenKeychain service to encrypt/decrypt messages, it might be necessary to disable battery optimizations for the OpenKeychain app.
4 years ago
**Important**: the OpenKeychain app reportedly needs contacts permission to work correctly.
4 years ago
**Important**: on some Android versions / devices it is necessary to enable *Show popups while running in background* in the additional permissions of the Android app settings of the OpenKeychain app. Without this permission the draft will be saved, but the OpenKeychain popup to confirm/select might not appear.
4 years ago
FairEmail will send the [Autocrypt](https://autocrypt.org/) header for use by other email clients, but only for signed and encrypted messages because too many email servers have problems with the often long Autocrypt header. Note that the most secure way to start an encrypted email exchange is by sending signed messages first. Received Autocrypt headers will be sent to the OpenKeychain app for storage on verifying a signature or decrypting a message.
4 years ago
All key handling is delegated to the OpenKey chain app for security reasons. This also means that FairEmail does not store PGP keys.
Inline encrypted PGP in received messages is supported, but inline PGP signatures and inline PGP in outgoing messages is not supported, see [here](https://josefsson.org/inline-openpgp-considered-harmful.html) about why not.
Signed-only or encrypted-only messages are not a good idea, please see here about why not:
* [OpenPGP Considerations Part I](https://k9mail.github.io/2016/11/24/OpenPGP-Considerations-Part-I.html)
* [OpenPGP Considerations Part II](https://k9mail.github.io/2017/01/30/OpenPGP-Considerations-Part-II.html)
* [OpenPGP Considerations Part III Autocrypt](https://k9mail.github.io/2018/02/26/OpenPGP-Considerations-Part-III-Autocrypt.html)
Signed-only messages are supported, encrypted-only messages are not supported.
Common errors:
4 years ago
* *No key*: there is no PGP key available for one of the listed email addresses
4 years ago
* *Missing key for encryption*: there is probably a key selected in FairEmail that does not exist in the OpenKeychain app anymore. Resetting the key (see above) will probably fix this problem.
*S/MIME*
Encrypting a message requires the public key(s) of the recipient(s). Signing a message requires your private key.
Private keys are stored by Android and can be imported via the Android advanced security settings. There is a shortcut (button) for this in the privacy settings. Android will ask you to set a PIN, pattern, or password if you didn't before. If you have a Nokia device with Android 9, please [read this first](https://nokiamob.net/2019/08/10/a-bug-prevents-nokia-1-owners-from-unlocking-their-screen-even-with-right-pin-pattern/).
Note that certificates can contains multiple keys for multiple purposes, for example for authentication, encryption and signing. Android only imports the first key, so to import all the keys, the certificate must first be split. This is not very trivial and you are advised to ask the certificate supplier for support.
4 years ago
Note that S/MIME signing with other algorithms than RSA is supported, but be aware that other email clients might not support this. S/MIME encryption is possible with symmetric algorithms only, which means in practice using RSA.
4 years ago
The default encryption method is PGP, but the last used encryption method will be remembered for the selected identity for the next time. You might need to enable the send options in the three dots menu again to be able to select the encryption method.
To allow different private keys for the same email address, FairEmail will always let you select a key when there are multiple identities with the same email address for the same account.
Public keys are stored by FairEmail and can be imported when verifying a signature for the first time or via the privacy settings (PEM or DER format).
FairEmail verifies both the signature and the complete certificate chain.

* *No certificate found matching targetContraints*: this likely means you are using an old version of FairEmail
* *unable to find valid certification path to requested target*: basically this means one or more intermediate or root certificates were not found
* *Private key does not match any encryption keys*: the selected key cannot be used to decrypt the message, probably because it is the incorrect key
* *No private key*: no certificate was selected or no certificate was available in the Android keystore
In case the certificate chain is incorrect, you can tap on the little info button to show the all certificates. After the certificate details the issuer or "selfSign" is shown. A certificate is self signed when the subject and the issuer are the same. Certificates from a certificate authority (CA) are marked with "[keyCertSign](https://tools.ietf.org/html/rfc5280#section-4.2.1.3)". 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](https://support.google.com/pixelphone/answer/2844832?hl=en) 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.

**(13) How does search on device/server work?**
4 years ago
4 years ago
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.
4 years ago
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.
4 years ago
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.
4 years ago
4 years ago
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.
4 years ago
4 years ago
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.
4 years ago
4 years ago
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](https://support.google.com/mail/answer/7190) for the possible search operators. For example:
4 years ago
`
raw:larger:10M`
4 years ago
Searching through a large number of messages on the device is not very fast because of two limitations:
4 years ago
4 years ago
* [sqlite](https://www.sqlite.org/), mesin database Android memiliki batasan ukuran rekaman yang mencegaj teks pesan disimpan di dalam database
* Aplikasi Andorid hanya mendapatkan memori yang terbatas untuk bekerja, bahkan ketika peangkat tersebut memiliki banyak memori yang masih tersedia
4 years ago
4 years ago
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.
4 years ago
4 years ago
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.
4 years ago
4 years ago
From version 1.1315 it is possible to use search expressions like this:
4 years ago
```
4 years ago
apel +pisang -ceri ?kacang
4 years ago
```
4 years ago
This will result in searching like this:
4 years ago
```
4 years ago
("apel" DAN "pisang" DAN TIDAK "ceri") ATAU "kacang"
4 years ago
```
4 years ago
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.
4 years ago
4 years ago
Searching on the device is a free feature, using the search index and searching on the server is a pro feature.

**(15) Why does the message text keep loading?**
4 years ago
4 years ago
The message header and message body are fetched separately from the server. The message text of larger messages is not being pre-fetched on metered connections and will be fetched on demand on expanding a message. The message text will keep loading if there is no connection to the account, see also the next question, or if there other operations, like synchronizing messages, are being executed.
4 years ago
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](#user-content-faq3) for the meaning of the operations).
4 years ago
If FairEmail is holding off because of prior connectivity issues, please see [this FAQ](#user-content-faq123), you can force synchronization via the three dots menu.

* Jumlah hari untuk mensingkronisasi pesan ditetapkan teralu pendek
* Tidak ada koneksi internet yang dapat digunakan
* Server surel yang tidak tersedia pada saat itu

4 years ago
**General errors**
4 years ago
4 years ago
<a name="authfailed"></a>
4 years ago
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.
4 years ago
4 years ago
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](#user-content-faq88) about how to set up a Yahoo account.
4 years ago
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*.
4 years ago
The error *... Couldn't connect to host ...* means that there was no response from the email server within a reasonable time (20 seconds by default). Mostly this indicates internet connectivity issues, possibly caused by a VPN or by a firewall app. You can try to increase the connection timeout in the connection settings of FairEmail, for when the email server is really slow.
4 years ago
The error *... Connection refused ...* means that the email server or something between the email server and the app, like a firewall, actively refused the connection.
The error *... Network unreachable ...* means that the email server was not reachable via the current internet connection, for example because internet traffic is restricted to local traffic only.
4 years ago
4 years ago
The error *... Host is unresolved ...*, *... Unable to resolve host ...* or *... No address associated with hostname ...* means that the address of the email server could not be resolved into an IP address. This might be caused by a VPN, ad blocking or an unreachable or not properly working (local) [DNS](https://en.wikipedia.org/wiki/Domain_Name_System) server.
4 years ago
4 years ago
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.
4 years ago
4 years ago
The errors *... BYE Logging out ...*, *... Connection reset ...* mean that the email server or something between the email server and the app, for example a router or a firewall (app), actively terminated an existing connection.
4 years ago
The error *... Connection closed by peer ...* might be caused by a not updated Exchange server, see [here](https://blogs.technet.microsoft.com/pki/2010/09/30/sha2-and-windows/) 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.
4 years ago
<a name="connectiondropped"></a>
The error *... Connection dropped by server? ...* means that the email server unexpectedly terminated the connection. This sometimes happen when there were too many connections in a too short time or when a wrong password was used for too many times. In this case, please make sure your password is correct and disable receiving in the receive settings for about 30 minutes and try again. If needed, see [this FAQ](#user-content-faq23) about how you can reduce the number of connections.
4 years ago
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](#user-content-faq23).

* *550 Spam message rejected because IP is listed by ...* means that the email server rejected to send a message from the current (public) network address because it was misused to send spam by (hopefully) somebody else before. Please try to enable flight mode for 10 minutes to acquire a new network address.
4 years ago
* *571 5.7.1 Message contains spam or virus or sender is blocked ...* means that the email server considered an outgoing message as spam. This probably means that the spam filters of the email server are too strict. You'll need to contact the email provider for support on this.
If you want to use the Gmail SMTP server to workaround a too strict outgoing spam filter or to improve delivery of messages:
* Verify your email address [here](https://mail.google.com/mail/u/0/#settings/accounts) (you'll need to use a desktop browser for this)

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

*Too many simultaneous connections* or *Maximum number of connections exceeded*

* 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)
4 years ago
4 years ago
An easy way to configure periodically checking for messages for all folders except the inbox is to use *Apply to all ...* in the three-dots menu of the folder list and to tick the bottom two advanced checkboxes.
4 years ago
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](https://support.google.com/mail/answer/7126229) for details.

When using a Dovecot server, you might want to change the setting [mail_max_userip_connections](https://doc.dovecot.org/settings/dovecot_core_settings/#mail-max-userip-connections).

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

**(25) Why can't I select/open/save an image, attachment or a file?**
4 years ago
4 years ago
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](https://developer.android.com/guide/topics/providers/document-provider), 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).
4 years ago
4 years ago
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.
4 years ago
The storage access framework is provided by the package *com.android.documentsui*, which is visible as *Files* app on some Android versions (notable OxygenOS).
4 years ago
You can enable the storage access framework (again) with this adb command:

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

**(33) Why are edited sender addresses not working?**
4 years ago
4 years ago
Most providers accept validated addresses only when sending messages to prevent spam.
4 years ago
4 years ago
For example Google modifies the message headers like this for *unverified* addresses:
4 years ago
```
4 years ago
Dari: Seseorang <somebody@example.org>
X-Google-Orisinal-Dari: Seseorang <somebody+extra@example.org>
4 years ago
```
4 years ago
This means that the edited sender address was automatically replaced by a verified address before sending the message.

**(34) How are identities matched?**
4 years ago
4 years ago
Identities are as expected matched by account. For incoming messages the *to*, *cc*, *bcc*, *from* and *(X-)delivered/envelope/original-to* addresses will be checked (in this order) and for outgoing messages (drafts, outbox and sent) only the *from* addresses will be checked. Equal addresses have precedence over partially matching addresses, except for *delivered-to* addresses.
4 years ago
4 years ago
The matched address will be shown as *via* in the addresses section of received messages (between the message header and message text).
4 years ago
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.
4 years ago
It is possible to configure a [regex](https://en.wikipedia.org/wiki/Regular_expression) in the identity settings to match **the username** of an email address (the part before the @ sign).
4 years ago
Note that the domain name (the parts after the @ sign) always needs to be equal to the domain name of the identity.
4 years ago
If you like to match a catch-all email address, this regex is mostly okay:
```
.*
```
4 years ago
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:
4 years ago
* Identity: abc@example.com; regex: **(?i)abc**
* Identity: xyz@example.com; regex: **(?i)xyz**
* Identity: main@example.com; regex: **^(?i)((?!abc|xyz).)\*$**
4 years ago
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) Why should I be careful with viewing images, attachments, the original message, and opening links?**
4 years ago
4 years ago
Viewing remotely stored images (see also [this FAQ](#user-content-faq27)) and opening links might not only tell the sender that you have seen the message, but will also leak your IP address. See also this question: [Why email's link is more dangerous than web search's link?](https://security.stackexchange.com/questions/241139/why-emails-link-is-more-dangerous-than-web-searchs-link).
4 years ago
Opening attachments or viewing an original message might load remote content and execute scripts, that might not only cause privacy sensitive information to leak, but can also be a security risk.
Note that your contacts could unknowingly send malicious messages if they got infected with malware.
FairEmail formats messages again causing messages to look different from the original, but also uncovering phishing links.
Note that reformatted messages are often better readable than original messages because the margins are removed, and font colors and sizes are standardized.
The Gmail app shows images by default by downloading the images through a Google proxy server. Since the images are downloaded from the source server [in real-time](https://blog.filippo.io/how-the-new-gmail-image-proxy-works-and-what-this-means-for-you/), this is even less secure because Google is involved too without providing much benefit.
You can show images and original messages by default for trusted senders on a case-by-case basis by checking *Do not ask this again for ...*.
If you want to reset the default *Open with* apps, please [see here](https://www.androidauthority.com/how-to-set-default-apps-android-clear-621269/).

All supported Android versions [encrypt all user data](https://source.android.com/security/encryption), so all data, including usernames, passwords, messages, etc, is stored encrypted.
If the device is secured with a PIN, pattern or password, you can make the account and identity passwords visible. If this is a problem because you are sharing the device with other people, consider to use [user profiles](https://www.howtogeek.com/333484/how-to-set-up-multiple-user-profiles-on-android/).

**(39) How can I reduce the battery usage of FairEmail?**
4 years ago
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*
4 years ago
As a rule of thumb the battery usage should be below or in any case not be much higher than *Mobile network standby*. If this isn't the case, please turn on *Auto optimize* in the receive settings. If this doesn't help, please [ask for support](https://contact.faircode.eu/?product=fairemailsupport).
4 years ago
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.
4 years ago
Reconnecting to an email server will use extra battery power, so an unstable internet connection will result in extra battery usage. Also, some email servers prematurely terminate idle connections, while [the standard](https://tools.ietf.org/html/rfc2177) says that an idle connection should be kept open for 29 minutes. In these cases you might want to synchronize periodically, for example each hour, instead of continuously. Note that polling frequently (more than every 30-60 minutes) will likely use more battery power than synchronizing always because connecting to the server and comparing the local and remote messages are expensive operations.
4 years ago
4 years ago
[On some devices](https://dontkillmyapp.com/) it is necessary to *disable* battery optimizations (setup step 3) to keep connections to email servers open. In fact, leaving battery optimizations enabled can result in extra battery usage for all devices, even though this sounds contradictory!
4 years ago
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.
4 years ago
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. After decreasing the number of days to keep messages for, you might want to run the cleanup in the miscellaneous settings to remove old files.
4 years ago
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.
4 years ago
Some providers don't follow the IMAP standard and don't keep connections open long enough, forcing FairEmail to reconnect often, causing extra battery usage. You can inspect the *Log* via the main navigation menu to check if there are frequent reconnects (connection closed/reset, read/write error/timeout, etc). You can workaround this by lowering the keep-alive interval in the advanced account settings to for example 9 or 15 minutes. Note that battery optimizations need to be disabled in setup step 3 to reliably keep connections alive.
4 years ago
Some providers send every two minutes something like '*Still here*' resulting in network traffic and your device to wake up and causing unnecessary extra battery usage. You can inspect the *Log* via the main navigation menu to check if your provider is doing this. If your provider is using [Dovecot](https://www.dovecot.org/) as IMAP server, you could ask your provider to change the [imap_idle_notify_interval](https://wiki.dovecot.org/Timeouts) setting to a higher value or better yet, to disable this. If your provider is not able or willing to change/disable this, you should consider to switch to periodically instead of continuous synchronization. You can change this in the receive settings.
If you got the message *This provider does not support push messages* while configuring an account, consider switching to a modern provider which supports push messages (IMAP IDLE) to reduce battery usage.
If your device has an [AMOLED](https://en.wikipedia.org/wiki/AMOLED) screen, you can save battery usage while viewing messages by switching to the black theme.
4 years ago
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:
4 years ago
* Says '*Still here*' within 3 minutes
* The email server does not support push messages
* The keep-alive interval is lower than 12 minutes
4 years ago
In addition, the trash and spam folders will be automatically set to checking for new messages after three successive [too many simultaneous connections](#user-content-faq23) errors.

**(40) How can I reduce the data usage of FairEmail?**
4 years ago
4 years ago
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).
4 years ago
4 years ago
To reduce data usage, you could change these advanced receive settings:
* Check if old messages were removed from the server: disable
* Synchronize (shared) folder list: disable
4 years ago
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.

<a name="faq41"></a>
**(41) How can I fix the error 'Handshake failed' ?**
There are several possible causes, so please read to the end of this answer.
The error '*Handshake failed ... WRONG_VERSION_NUMBER ...*' might mean that you are trying to connect to an IMAP or SMTP server without an encrypted connection, typically using port 143 (IMAP) and port 25 (SMTP), or that a wrong protocol (SSL/TLS or STARTTLS) is being used.
Most providers provide encrypted connections using different ports, typically port 993 (IMAP) and port 465/587 (SMTP).
If your provider doesn't support encrypted connections, you should ask to make this possible. If this isn't an option, you could enable *Allow insecure connections* both in the advanced settings AND the account/identity settings.
See also [this FAQ](#user-content-faq4).
The error '*Handshake failed ... SSLV3_ALERT_ILLEGAL_PARAMETER ...*' is either caused by a bug in the SSL protocol implementation or by a too short DH key on the email server and can unfortunately not be fixed by FairEmail.
The error '*Handshake failed ... HANDSHAKE_FAILURE_ON_CLIENT_HELLO ...*' might be caused by the provider still using RC4, which isn't supported since [Android 7](https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl) anymore.
4 years ago
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.
4 years ago
Android 8 Oreo and later [do not support](https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all) SSLv3 anymore. There is no way to workaround lacking RC4 and SSLv3 support because it has completely been removed from Android (which should say something).
You can use [this website](https://ssl-tools.net/mailservers) or [this website](https://www.immuniweb.com/ssl/) to check for SSL/TLS problems of email servers.

**(42) Can you add a new provider to the list of providers?**
4 years ago
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](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery): "*Additionally, even if you configure STARTTLS perfectly and use a valid certificate, theres still no guarantee your communication will be encrypted.*"
So, pure SSL connections are safer than using [STARTTLS](https://en.wikipedia.org/wiki/Opportunistic_TLS) and therefore preferred.
Please make sure receiving and sending messages works properly before contacting me to add a provider.

**(46) Why does the message list keep refreshing?**
4 years ago
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](#user-content-faq39).

**(47) How do I solve the error 'No primary account or no drafts folder' ?**
4 years ago
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.

**(49) How do I fix 'An outdated app sent a file path instead of a file stream' ?**
You likely selected or sent an attachment or image with an outdated file manager or an outdated app which assumes all apps still have storage permissions. For security and privacy reasons modern apps like FairEmail have no full access to all files anymore. This can result into the error message *An outdated app sent a file path instead of a file stream* if a file name instead of a file stream is being shared with FairEmail because FairEmail cannot randomly open files.
You can fix this by switching to an up-to-date file manager or an app designed for recent Android versions. Alternatively, you can grant FairEmail read access to the storage space on your device in the Android app settings. Note that this workaround [won't work on Android Q](https://developer.android.com/preview/privacy/scoped-storage) anymore.

**(53) Can you stick the message action bar to the top/bottom?**
4 years ago
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.

**(61) Why are some messages shown dimmed?**
4 years ago
Messages shown dimmed (grayed) are locally moved messages for which the move is not confirmed by the server yet. This can happen when there is no connection to the server or the account (yet). These messages will be synchronized after a connection to the server and the account has been made or, if this never happens, will be deleted if they are too old to be synchronized.
You might need to manually synchronize the folder, for example by pulling down.
You can view these messages, but you cannot move these messages again until the previous move has been confirmed.
Pending [operations](#user-content-faq3) are shown in the operations view accessible from the main navigation menu.

**(62) Which authentication methods are supported?**
The following authentication methods are supported and used in this order:
* LOGIN
* PLAIN
* CRAM-MD5
* XOAUTH2 ([Gmail](https://developers.google.com/gmail/imap/xoauth2-protocol), [Yandex](https://tech.yandex.com/oauth/))
* NTLM (untested)
SASL authentication methods, besides CRAM-MD5, are not supported because [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication.
If your provider requires an unsupported authentication method, you'll likely get the error message *authentication failed*.
[Server Name Indication](https://en.wikipedia.org/wiki/Server_Name_Indication) is supported by [all supported Android versions](https://developer.android.com/training/articles/security-ssl).

**(63) How are images resized for displaying on screens?**
4 years ago
Large inline or attached [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) and [JPEG](https://en.wikipedia.org/wiki/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](https://f-droid.org/en/packages/mobi.omegacentauri.SendReduced/) or a similar app.

**~~(64) Can you add custom actions for swipe left/right?~~**
4 years ago
~~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.~~

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](#user-content-faq71).
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.

There is one exception: the message was not downloaded yet and the message is too large to download automatically on a metered (mobile) connection. You can set or disable the maximum message size on the 'connection' settings tab.
Duplicate (archived) messages, trashed messages and draft messages are not counted.
Messages will automatically be marked read on expanding, unless this was disabled in the individual account settings.

**(71) How do I use filter rules?**
4 years ago
4 years ago
You can edit filter rules by long pressing a folder in the folder list of an account (tap the account name in the navigation/side menu).
4 years ago
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
4 years ago
* Has attachments
4 years ago
* 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](https://en.wikipedia.org/wiki/Regular_expression). Please see [here](https://developer.android.com/reference/java/util/regex/Pattern) for the documentation of Java regular expressions. You can test a regex [here](https://regexr.com/).
Note that a regular expression supports an *or* operator, so if you want to match multiple senders, you can do this:
`
.*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.*`
Note that [dot all mode](https://developer.android.com/reference/java/util/regex/Pattern#DOTALL) is enabled to be able to match [unfolded headers](https://tools.ietf.org/html/rfc2822#section-3.2.3).
You can select one of these actions to apply to matching messages:
* No action (useful for *not*)
* Mark as read
* Mark as unread
* Hide
* Suppress notification
* Snooze
* Add star
* Set importance (local priority)
* Add keyword
* Move
* Copy (Gmail: label)
4 years ago
* Answer/forward (with template)
4 years ago
* 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.
4 years ago
Some common header conditions (regex):
* *.&ast;Auto-Submitted:.&ast;* [RFC3834](https://tools.ietf.org/html/rfc3834)
* *.&ast;Content-Type: multipart/report.&ast;* [RFC3462](https://tools.ietf.org/html/rfc3462)
4 years ago
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.

**(73) Is moving messages across accounts safe/efficient?**
4 years ago
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.
<br />
<a name="faq74"></a>
**(74) Why do I see duplicate messages?**
Some providers, notably Gmail, list all messages in all folders, except trashed messages, in the archive (all messages) folder too. FairEmail shows all these messages in a non obtrusive way to indicate that these messages are in fact the same message.
Gmail allows one message to have multiple labels, which are presented to FairEmail as folders. This means that messages with multiple labels will be shown multiple times as well.

<a name="faq77"></a>

**(77) Why are messages sometimes shown with a small delay?**
4 years ago
Depending on the speed of your device (processor speed and maybe even more memory speed) messages might be displayed with a small delay. FairEmail is designed to dynamically handle a large number of messages without running out of memory. This means that messages needs to be read from a database and that this database needs to be watched for changes, both of which might cause small delays.
Some convenience features, like grouping messages to display conversation threads and determining the previous/next message, take a little extra time. Note that there is no *the* next message because in the meantime a new message might have been arrived.
When comparing the speed of FairEmail with similar apps this should be part of the comparison. It is easy to write a similar, faster app which just displays a lineair list of messages while possible using too much memory, but it is not so easy to properly manage resource usage and to offer more advanced features like conversation threading.
FairEmail is based on the state-of-the-art [Android architecture components](https://developer.android.com/topic/libraries/architecture/), so there is little room for performance improvements.

**(78) How do I use schedules?**
4 years ago
4 years ago
In the receive settings you can enable scheduling and set a time period and the days of the week *when* messages should be *received*. Note that an end time equal to or earlier than the start time is considered to be 24 hours later.
4 years ago
4 years ago
Automation, see below, can be used for more advanced schedules, like for example multiple synchronization periods per day or different synchronization periods for different days.
It is possible to install FairEmail in multiple user profiles, for example a personal and a work profile, and to configure FairEmail differently in each profile, which is another possibility to have different synchronization schedules and to synchronize a different set of accounts.
It is also possible to create [filter rules](#user-content-faq71) with a time condition and to snooze messages until the end time of the time condition. This way it is possible to *snooze* business related messages until the start of the business hours. This also means that the messages will be on your device for when there is (temporarily) no internet connection.
Note that recent Android versions allow overriding DND (Do Not Disturb) per notification channel and per app, which could be used to (not) silence specific (business) notifications. Please [see here](https://support.google.com/android/answer/9069335) for more information.
4 years ago
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](https://tasker.joaoapps.com/userguide/en/intents.html):
```
New task: Something recognizable
Action Category: Misc/Send Intent
Action: eu.faircode.email.ENABLE
Target: Service
```
To enable/disable an account with the name *Gmail*:
```
Extras: account:Gmail
```
Account names are case sensitive.
Scheduling is a pro feature.

**(79) How do I use synchronize on demand (manual)?**
4 years ago
Normally, FairEmail maintains a connection to the configured email servers whenever possible to receive messages in real-time. If you don't want this, for example to be not disturbed or to save on battery usage, just disable receiving in the receive settings. This will stop the background service which takes care of automatic synchronization and will remove the associated status bar notification.
You can also enable *Synchronize manually* in the advanced account settings if you want to manually synchronize specific accounts only.
You can use pull-down-to-refresh in a message list or use the folder menu *Synchronize now* to manually synchronize messages.
If you want to synchronize some or all folders of an account manually, just disable synchronization for the folders (but not of the account).
You'll likely want to disabled [browse on server](#user-content-faq24) too.

**(84) What are local contacts for?**
4 years ago
Local contact information is based on names and addresses found in incoming and outgoing messages.
The main use of the local contacts storage is to offer auto completion when no contacts permission has been granted to FairEmail.
Another use is to generate [shortcuts](#user-content-faq31) on recent Android versions to quickly send a message to frequently contacted people. This is also why the number of times contacted and the last time contacted is being recorded and why you can make a contact a favorite or exclude it from favorites by long pressing it.
The list of contacts is sorted on number of times contacted and the last time contacted.
By default only names and addresses to whom you send messages to will be recorded. You can change this in the send settings.

**(90) Why are some texts linked while not being a link?**
FairEmail will automatically link not linked web links (http and https) and not linked email addresses (mailto) for your convenience. However, texts and links are not easily distinguished, especially not with lots of [top level domains](https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains) being words. This is why texts with dots are sometimes incorrectly recognized as links, which is better than not recognizing some links.
4 years ago
Links for the tel, geo, rtsp and xmpp protocols will be recognized too, but links for less usual or less safe protocols like telnet and ftp will not be recognized. The regex to recognize links is already *very* complex and adding more protocols will make it only slower and possibly cause errors.

**(92) Can you add spam filtering, verification of the DKIM signature and SPF authorization?**
Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client. Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices. Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client. Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to.
4 years ago
Spam filtering based on message headers might have been feasible, but unfortunately this technique is [patented by Microsoft](https://patents.google.com/patent/US7543076).
4 years ago
Recent versions of FairEmail can filter spam to a certain extend using a message classifier. Please see [this FAQ](#user-content-faq163) for more information about this.
4 years ago
Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#user-content-faq71) too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.
4 years ago
Note that the POP3 protocol gives access to the inbox only. So, it is won't be possible to report spam for POP3 accounts.
4 years ago
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](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server. You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings.
FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server. This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.
If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated. The sender might use [this tool](https://www.mail-tester.com/) to check authentication and other things.

**(95) Why are not all apps shown when selecting an attachment or image?**
4 years ago
For privacy and security reasons FairEmail does not have permissions to directly access files, instead the Storage Access Framework, available and recommended since Android 4.4 KitKat (released in 2013), is used to select files.
If an app is listed depends on if the app implements a [document provider](https://developer.android.com/guide/topics/providers/document-provider). If the app is not listed, you might need to ask the developer of the app to add support for the Storage Access Framework.
Android Q will make it harder and maybe even impossible to directly access files, see [here](https://developer.android.com/preview/privacy/scoped-storage) and [here](https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/) for more details.

**(97) What is 'cleanup' ?**
About each four hours FairEmail runs a cleanup job that:

**(98) Why can I still pick contacts after revoking contacts permissions?**
4 years ago
After revoking contacts permissions Android does not allow FairEmail access to your contacts anymore. However, picking contacts is delegated to and done by Android and not by FairEmail, so this will still be possible without contacts permissions.

**(99) Can you add a rich text or markdown editor?**
FairEmail provides common text formatting (bold, italic, underline, text size and color) via a toolbar that appears after selecting some text.
A [Rich text](https://en.wikipedia.org/wiki/Formatted_text) or [Markdown](https://en.wikipedia.org/wiki/Markdown) editor would not be used by many people on a small mobile device and, more important, Android doesn't support a rich text editor and most rich text editor open source projects are abandoned. See [here](https://forum.xda-developers.com/showpost.php?p=79061829&postcount=4919) for some more details about this.

**(100) How can I synchronize Gmail categories?**
4 years ago
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.

Images will automatically be rotated when automatic resizing of images is enabled in the settings (enabled by default). However, automatic rotating depends on the [Exif](https://en.wikipedia.org/wiki/Exif) information to be present and to be correct, which is not always the case. Particularly not when taking a photo with a camara app from FairEmail.
Note that only [JPEG](https://en.wikipedia.org/wiki/JPEG) and [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) images can contain Exif information.

**(106) Which launchers can show a badge count with the number of unread messages?**
4 years ago
Please [see here](https://github.com/leolin310148/ShortcutBadger#supported-launchers) 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](#user-content-faq2), despite FairEmail explicitly requesting not to show a badge for this notification. This could be caused by a bug in the launcher app or in your Android version. Please double check if the notification dot 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](https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415).
FairEmail does send a new message count intent as well:
```
eu.faircode.email.NEW_MESSAGE_COUNT
```
The number of new, unread messages will be in an integer "*count*" parameter.

**(107) How do I use colored stars?**
4 years ago
You can set a colored star via the *more* message menu, via multiple selection (started by long pressing a message), by long pressing a star in a conversation or automatically by using [rules](#user-content-faq71).
You need to know that colored stars are not supported by the IMAP protocol and can therefore not be synchronized to an email server. This means that colored stars will not be visible in other email clients and will be lost on downloading messages again. However, the stars (without color) will be synchronized and will be visible in other email clients, when supported.
Some email clients use IMAP keywords for colors. However, not all servers support IMAP keywords and besides that there are no standard keywords for colors.

~~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:~~

**(110) Why are (some) messages empty and/or attachments corrupt?**

Empty messages and/or corrupt attachments are probably being caused by a bug in the server software. Older Microsoft Exchange software is known to cause this problem. Mostly you can workaround this by disabling *Partial fetch* in the advanced account settings:
4 years ago
Settings > Manual setup and more options > Accounts > tap account > tap advanced > Partial fetch > uncheck
4 years ago
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.

**(112) Which email provider do you recommend?**
4 years ago
4 years ago
FairEmail is an email client only, so you need to bring your own email address. Note that this is clearly mentioned in the app description.
4 years ago
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](https://restoreprivacy.com/secure-email/) or [Privacy Tools](https://www.privacytools.io/providers/email/) 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](#user-content-faq129) for more information.
Using your own (custom) domain name, which is supported by most email providers, will make it easier to switch to another email provider.

**(113) How does biometric authentication work?**
4 years ago
4 years ago
If your device has a biometric sensor, for example a fingerprint sensor, you can enable/disable biometric authentication in the navigation (hamburger) menu of the settings screen. When enabled FairEmail will require biometric authentication after a period of inactivity or after the screen has been turned off while FairEmail was running. Activity is navigation within FairEmail, for example opening a conversation thread. The inactivity period duration can be configured in the miscellaneous settings. When biometric authentication is enabled new message notifications will not show any content and FairEmail won't be visible on the Android recents screen.
4 years ago
Biometric authentication is meant to prevent others from seeing your messages only. FairEmail relies on device encryption for data encryption, see also [this FAQ](#user-content-faq37).
Biometric authentication is a pro feature.

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

4 years ago
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 wizard is simple, so it is not really worth the effort.

**(115) Can you add email address chips?**
Email address [chips](https://material.io/design/components/chips.html) look nice, but cannot be edited, which is quite inconvenient when you made a typo in an email address.
Note that FairEmail will select the address only when long pressing an address, which makes it easy to delete an address.
Chips are not suitable for showing in a list and since the message header in a list should look similar to the message header of the message view it is not an option to use chips for viewing messages.

* 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

* 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

**(120) Why are new message notifications not removed on opening the app?**
4 years ago
New message notifications will be removed on swiping notifications away or on marking the associated messages read. Opening the app will not remove new message notifications. This gives you a choice to leave new message notifications as a reminder that there are still unread messages.
On Android 7 Nougat and later new message notifications will be [grouped](https://developer.android.com/training/notify-user/group). Tapping on the summary notification will open the unified inbox. The summary notification can be expanded to view individual new message notifications. Tapping on an individual new message notification will open the conversation the message it is part of. See [this FAQ](#user-content-faq70) about when messages in a conversation will be auto expanded and marked read.

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.

**(123) What will happen when FairEmail cannot connect to an email server?**
4 years ago
4 years ago
If FairEmail cannot connect to an email server to synchronize messages, for example if the internet connection is bad or a firewall or a VPN is blocking the connection, FairEmail will retry two times after waiting 4 and 8 seconds while keeping the device awake (=use battery power). If this fails, FairEmail will schedule an alarm to retry after 15, 30 and eventually every 60 minutes and let the device sleep (=no battery usage).
4 years ago
Note that [Android doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) does not allow to wake the device earlier than after 15 minutes.
*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.
4 years ago
Note that sending will not be retried in case of authentication problems and when the server rejected the message. In this case you can pull down the outbox to try again.

**(126) Can message previews be sent to my wearable?**
4 years ago
FairEmail fetches a message in two steps:
1. Fetch message headers
1. Fetch message text and attachments
Directly after the first step new messages will be notified. However, only until after the second step the message text will be available. FairEmail updates exiting notifications with a preview of the message text, but unfortunately wearable notifications cannot be updated.
Since there is no guarantee that a message text will always be fetched directly after a message header, it is not possible to guarantee that a new message notification with a preview text will always be sent to a wearable.
4 years ago
If you think this is good enough, you can enable the notification option *Only send notifications with a message preview to wearables* and if this does not work, you can try to enable the notification option *Show notifications with a preview text only*. Note that this applies to wearables not showing a preview text too, even when the Android Wear app says the notification has been sent (bridged).
4 years ago
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.

**(130) What does message error ... mean?**
4 years ago
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.

4 years ago
Notifications are silent by default on some MIUI versions. Please see [here](http://en.miui.com/thread-3930694-1-1.html) how you can fix this.
There is a bug in some Android versions causing [setOnlyAlertOnce](https://developer.android.com/reference/android/app/Notification.Builder#setOnlyAlertOnce(boolean)) to mute notifications. Since FairEmail shows new message notifications right after fetching the message headers and FairEmail needs to update new message notifications after fetching the message text later, this cannot be fixed or worked around by FairEmail.
Android might rate limit the notification sound, which can cause some new message notifications to be silent.

* 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*

**(140) Why does the message text contain strange characters?**
4 years ago
Displaying strange characters is almost always caused by specifying no or an invalid character encoding by the sending software. FairEmail will assume [ISO 8859-1](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) when no character set or when [US-ASCII](https://en.wikipedia.org/wiki/ASCII) was specified. Other than that there is no way to reliably determine the correct character encoding automatically, so this cannot be fixed by FairEmail. The right action is to complain to the sender.

**(141) How can I fix 'A drafts folder is required to send messages'?**
4 years ago
To store draft messages a drafts folder is required. In most cases FairEmail will automatically select the drafts folders on adding an account based on [the attributes](https://www.iana.org/assignments/imap-mailbox-name-attributes/imap-mailbox-name-attributes.xhtml) the email server sends. However, some email servers are not configured properly and do not send these attributes. In this case FairEmail tries to identify the drafts folder by name, but this might fail if the drafts folder has an unusual name or is not present at all.
4 years ago
You can fix this problem by manually selecting the drafts folder in the account settings (Settings, tap Manual setup and more options, tap Accounts, tap account, at the bottom). If there is no drafts folder at all, you can create a drafts folder by tapping on the '+' button in the folder list of the account (tap on the account name in the navigation menu).

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

**(142) How can I store sent messages in the inbox?**
4 years ago
Generally, it is not a good idea to store sent messages in the inbox because this is hard to undo and could be incompatible with other email clients.
That said, FairEmail is able to properly handle sent messages in the inbox. FairEmail will mark outgoing messages with a sent messages icon for example.
The best solution would be to enable showing the sent folder in the unified inbox by long pressing the sent folder in the folder list and enabling *Show in unified inbox*. This way all messages can stay where they belong, while allowing to see both incoming and outgoing messages at one place.
If this is not an option, you can [create a rule](#user-content-faq71) to automatically move sent messages to the inbox or set a default CC/BCC address in the advanced identity settings to send yourself a copy.

**~~(143) Can you add a trash folder for POP3 accounts?~~**
4 years ago
[POP3](https://en.wikipedia.org/wiki/Post_Office_Protocol) is a very limited protocol. Basically only messages can be downloaded and deleted from the inbox. It is not even possible to mark a message read.
Since POP3 does not allow access to the trash folder at all, there is no way to restore trashed messages.
Note that you can hide messages and search for hidden messages, which is similar to a local trash folder, without suggesting that trashed messages can be restored, while this is actually not possible.
Version 1.1082 added a local trash folder. Note that trashing a message will permanently remove it from the server and that trashed messages cannot be restored to the server anymore.

**(146) How can I fix incorrect message times?**
4 years ago
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.
4 years ago
In these rare cases, it is possible to let FairEmail use either the date/time from the *Date* header (sent time) or from the *Received* header as a workaround. This can be changed in the advanced account settings: Settings, tap Manual setup and more options, tap Accounts, tap account, tap Advanced.
4 years ago
This will not change the time of already synchronized messages. To solve this, long press the folder(s) in the folder list and select *Delete local messages* and *Synchronize now*.

**(147) What should I know about third party versions?**
4 years ago
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.
4 years ago
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 app signature only. For all other email providers, OAuth access is only available in Play Store versions and Github releases, as the email providers only permit the use of OAuth for official builds.
4 years ago
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](https://github.com/M66B/FairEmail/blob/master/README.md#user-content-downloads) for all download options.
If you have a problem with the F-Droid build, please check if there is a newer GitHub version first.

* a folder list when a specific account was selected and when new message notifications are enabled for multiple folders
* a list of messages when a specific account was selected and when new message notifications are enabled for one folder

**(150) Can you add cancelling calendar invites?**
4 years ago
Cancelling calendar invites (removing calendar events) requires write calendar permission, which will result in effectively granting permission to read and write *all* calendar events of *all* calendars.
Given the goal of FairEmail, privacy and security, and given that it is easy to remove a calendar event manually, it is not a good idea to request this permission for just this reason.
Inserting new calendar events can be done without permissions with special [intents](https://developer.android.com/guide/topics/providers/calendar-provider.html#intents). Unfortunately, there exists no intent to delete existing calendar events.

**(151) Can you add backup/restore of messages?**
4 years ago
An email client is meant to read and write messages, not to backup and restore messages. Note that breaking or losing your device, means losing your messages!
Instead, the email provider/server is responsible for backups.
If you want to make a backup yourself, you could use a tool like [imapsync](https://imapsync.lamiral.info/).
If you want to import an mbox file to an existing email account, you can use Thunderbird on a desktop computer and the [ImportExportTools](https://addons.thunderbird.net/nl/thunderbird/addon/importexporttools/) add-on.

**(153) Why does permanently deleting Gmail message not work?**
4 years ago
You might need to change [the Gmail IMAP settings](https://mail.google.com/mail/u/0/#settings/fwdandpop) on a desktop browser to make it work:
* When I mark a message in IMAP as deleted: Auto-Expunge off - Wait for the client to update the server.
* When a message is marked as deleted and expunged from the last visible IMAP folder: Immediately delete the message forever
Note that archived messages can be deleted only by moving them to the trash folder first.
Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view.

**(158) Which camera / audio recorder do you recommend?**
4 years ago
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:
* [Open Camera](https://play.google.com/store/apps/details?id=net.sourceforge.opencamera) ([F-Droid](https://f-droid.org/en/packages/net.sourceforge.opencamera/))
4 years ago

4 years ago
To record voice notes, etc, the audio recorder needs to support [MediaStore.Audio.Media.RECORD_SOUND_ACTION](https://developer.android.com/reference/android/provider/MediaStore.Audio.Media#RECORD_SOUND_ACTION). Oddly, most audio recorders seem not to support this standard Android action.

**(159) What are Disconnect's tracker protection lists?**
Please see [here](https://disconnect.me/trackerprotection) 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](https://disconnect.me/trackerprotection#trackers-we-dont-block) for more information.
This command can be sent to FairEmail from an automation app to update the protection lists:
```
(adb shell) am startservice -a eu.faircode.email.DISCONNECT.ME
```
Updating once a week will probably be sufficient, please see [here](https://github.com/disconnectme/disconnect-tracking-protection/commits/master) for recent lists changes.

**(160) Can you add permanent deletion of messages without confirmation?**
4 years ago
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 :-(
4 years ago
Advanced: the IMAP delete flag in combination with the EXPUNGE command is not supportable because both email servers and not all people can handle this, risking unexpected loss of messages. A complicating factor is that not all email servers support [UID EXPUNGE](https://tools.ietf.org/html/rfc4315).

Yes, [IMAP NOTIFY](https://tools.ietf.org/html/rfc5465) has been supported since version 1.1413.
IMAP NOTIFY support means that notifications for added, changed or deleted messages of all *subscribed* folders will be requested and if a notification is received for a subscribed folder, that the folder will be synchronized. Synchronization for subscribed folders can therefore be disable, saving folder connections to the email server.
**Important**: push messages (=always sync) for the inbox and subscription management (receive settings) need to be enabled.
**Important**: most email servers do not support this! You can check the log via the navigation menu if an email server supports the NOTIFY capability.

**(163) What is message classification?**
4 years ago
*This is an experimental feature!*
4 years ago
4 years ago
Message classification will attempt to automatically group emails into classes, based on their contents, using [Bayesian statistics](https://en.wikipedia.org/wiki/Bayesian_statistics). In the context of FairEmail, a folder is a class. So, for example, the inbox, the spam folder, a 'marketing' folder, etc, etc.
4 years ago
4 years ago
You can enable message classification in the miscellaneous settings. This will enable 'learning' mode only. The classifier will 'learn' from new messages in the inbox and spam folder by default. The folder property *Classify new messages in this folder* will enable or disable 'learning' mode for a folder. You can clear local messages (long press a folder in the folder list of an account) and synchronize the messages again to classify existing messages.
4 years ago
4 years ago
Each folder has an option *Automatically move classified messages to this folder* ('auto classification' for short). When this is turned on, new messages in other folders which the classifier thinks belong to that folder will be automatically moved.
4 years ago
4 years ago
The option *Use local spam filter* in the report spam dialog will turn on message classification in the miscellaneous settings and auto classification for the spam folder. Please understand that this is not a replacement for the spam filter of the email server and can result in [false positives and false negatives](https://en.wikipedia.org/wiki/False_positives_and_false_negatives). See also [this FAQ](#user-content-faq92).
4 years ago
4 years ago
A practical example: suppose there is a folder 'marketing' and auto message classification is enabled for this folder. Each time you move a message into this folder you'll train FairEmail that similar messages belong in this folder. Each time you move a message out of this folder you'll train FairEmail that similar messages do not belong in this folder. After moving some messages into the 'marketing' folder, FairEmail will start moving similar messages automatically into this folder. Or, the other way around, after moving some messages out of the 'marketing' folder, FairEmail will stop moving similar messages automatically into this folder. This will work best with messages with similar content (email addresses, subject and message text).

4 years ago
Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess. If the classifier is unsure, it will simply leave an email where it is.
4 years ago
To prevent the email server from moving a message into the spam folder again and again, auto classification out of the spam folder will not be done.
4 years ago
The message classifier calculates the probability a message belongs in a folder (class). There are two options in the miscellaneous settings which control if a message will be automatically moved into a folder, provided that auto classification is enabled for the folder:
4 years ago
4 years ago
* *Minimum class probability*: a message will only be moved when the confidence it belongs in a folder is greater than this value (default 20 %)
* *Minimum class difference*: a message will only be moved when the difference in confidence between one class and the next most likely class is greater than this value (default 50 %)
Both conditions must be satisfied before a message will be moved.
4 years ago
Considering the defaults option values:
* Apples 40 % and bananas 30 % would be disregarded because the difference of 25 % is below the minimum of 50 %
* Apples 15 % and bananas 5 % would be disregarded because the probability for apples is below the minimum of 20 %
* Apples 50 % and bananas 20 % would result in selecting apples
4 years ago
Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.
4 years ago
You can delete all classification data by turning classification in the miscellaneous settings three times off.
