|
<p>In most cases, the quick setup wizard will be able to automatically
|
|
|
identify the correct configuration.</p>
|
|
|
<p>If the quick setup wizard fails, you’ll need to manually set up an
|
|
|
account (to receive email) and an identity (to send email). For this
|
|
|
you’ll need the IMAP and SMTP server addresses and port numbers, whether
|
|
|
SSL/TLS or STARTTLS should be used and your username (mostly, but not
|
|
|
always, your email address) and your password.</p>
|
|
|
<p>Searching for <em>IMAP</em> and the name of the provider is mostly
|
|
|
sufficient to find the right documentation.</p>
|
|
|
<p>In some cases, you’ll need to enable external access to your account
|
|

and/or to use a special (app) password, for instance when two-factor

send messages to and will use this list for contact suggestions when no

you should know that the next click will open the unified

a service, which will let Android display a status bar notification

|
|
notifying you about potential battery usage.</p>
|
|
|
<p>The service can’t be started without a notification and the app can’t

|
|
disable the notification either. However, you can disable the

|
|
notification yourself, without side effects, via the notification
|
|
|
settings of FairEmail:</p>
|
|
|
<ul>
|
|
|
<li>Android 8 Oreo and later: tap the <em>Monitoring channel</em> button
|
|
|
and disable the channel via the Android settings (this won’t disable new
|
|
|
message notifications)</li>
|
|
|
<li>Android 7 Nougat and before: enabled <em>Use background service to

|
|
synchronize messages</em>, but be sure to read the remark below the

|
setting first</li>
|
|
|
</ul>
|
|
|
<p>You can also switch to periodically synchronization of messages in
|
|
|
the receive settings to remove the notification, but be aware that this
|
|
|
might use more battery power. See <a href="#faq39">here</a> for more
|
|
|
details about battery usage.</p>
|
|
|
<p>Android 8 Oreo might also show a status bar notification with the
|
|
|
text <em>Apps are running in the background</em>. Please see <a
|
|
|
href="https://www.reddit.com/r/Android/comments/7vw7l4/psa_turn_off_background_apps_notification/">here</a>
|
|
|
about how you can disable this notification.</p>
|
|
|
<p><em>Background</em></p>
|
|

<p>The service is a <a
|
|
|

|
|
|
<p>Most, if not all, other email apps don’t show a notification with a

“side effect” that new messages are often not or late being reported and

that messages are not or late being sent.</p>

|
|
|
<p><strong>Since version 1.2137: Due to <a
|
|
|
href="https://support.google.com/faqs/answer/6346016">Google’s Play
|
|
|
Store policies</a>, it is no longer possible to support insecure
|
|
|
connections to email servers with certificate issues for the version of
|
|
|
FairEmail distributed in the Play Store. Therefore, this issue can only
|
|
|
be resolved by your email provider, or by installing the GitHub version
|
|
|
of the app (as an update) and enabling insecure connections in the
|
|
|
account/identity settings.</strong></p>
|
|
|
<p><em>… Untrusted … not in certificate …</em><br /> <em>… Invalid
|
|
|
security certificate (Can’t verify identity of server) …</em><br />
|
|
|
<em>… Chain validation failed … timestamp check failed … Certificate
|
|
|
expired at …</em><br /></p>
|
|
|
<p>This can be caused by using an incorrect host name, so first double
|
|
|
check the host name in the advanced identity/account settings (tap
|
|
|
<em>Manual setup and account options</em>). Please see the documentation
|
|
|
of the email provider about the right host name. Sometimes the right
|
|
|
host name is in the error message.</p>
|
|
|
<p>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 <a
|
|
|
href="https://en.wikipedia.org/wiki/Man-in-the-middle_attack">man-in-the-middle
|
|
|
attacks</a>. If money is an obstacle, you can get free security
|
|
|
certificates from <a href="https://letsencrypt.org">Let’s
|
|
|
Encrypt</a>.</p>
|
|
|
<p>The quick, but unsafe solution (not advised), is to enable
|
|
|
<em>Insecure connections</em> in the advanced identity settings
|
|
|
(navigation menu, tap <em>Settings</em>, tap <em>Manual setup</em>, tap
|
|
|
<em>Identities</em>, tap the identity, tap <em>Advanced</em>).</p>
|
|
|
<p>Alternatively, you can accept the fingerprint of invalid server
|
|
|
certificates like this:</p>
|
|
|
<ol type="1">
|
|
|
<li>Make sure you are using a trusted internet connection (no public
|
|
|
Wi-Fi networks, etc)</li>
|
|
|
<li>Go to the setup screen via the navigation menu (swipe from the left
|
|
|
side inwards)</li>
|
|
|
<li>Tap Manual setup, tap Accounts/Identities and tap the faulty account
|
|
|
and identity</li>
|
|
|
<li>Check/save the account and identity</li>
|
|
|
<li>Tick the checkbox below the error message and save again</li>
|
|
|
</ol>
|
|
|
<p>This will “pin” the server certificate to prevent man-in-the-middle
|
|
|
attacks.</p>
|
|
|
<p>Note that older Android versions might not recognize newer
|
|
|
certification authorities like Let’s Encrypt causing connections to be
|
|
|
considered insecure, see also <a
|
|
|
href="https://developer.android.com/training/articles/security-ssl">here</a>.</p>
|
|
|
<p><br /></p>
|
|
|
<p><em>Trust anchor for certification path not found</em></p>
|
|
|
<p><em>… java.security.cert.CertPathValidatorException: Trust anchor for
|
|
|
certification path not found …</em> means that the default Android trust
|
|
|
manager was not able to verify the server certificate chain.</p>
|
|
|
<p>This could be due to the root certificate not being installed on your
|
|
|
device or because intermediate certificates are missing, for example
|
|
|
because the email server didn’t send them.</p>
|
|
|
<p>You can fix the first problem by downloading and installing the root
|
|
|
certificate from the website of the provider of the certificate.</p>
|
|
|
<p>The second problem should be fixed by changing the server
|
|
|
configuration or by importing the intermediate certificates on your
|
|
|
device.</p>
|
|
|
<p>You can pin the certificate too, see above.</p>
|
|
|
<p><br /></p>
|
|
|
<p><em>Empty password</em></p>
|
|
|
<p>Your username is likely easily guessed, so this is pretty insecure,
|
|
|
unless the SMTP server is available via a restricted local network or a
|
|
|
VPN only.</p>
|
|
|
<p><em>Plain text connection</em></p>
|
|
|
<p>Your username and password and all messages will be sent and received
|
|
|
unencrypted, which is <strong>very insecure</strong> because a <a
|
|
|
href="https://en.wikipedia.org/wiki/Man-in-the-middle_attack">man-in-the-middle
|
|
|
attack</a> is very simple on an unencrypted connection.</p>
|
|
|
<p>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,
|

|
|
|
<p>Note that this won’t work on devices without Google Play

Store/Services, such as recent Huawei devices. In this case you will

|
|
need to use an app password, see below.</p>
|
|
|
<p><strong>Note that other email apps, possibly on other devices, which

still use your account password could cause your account to be

|
|
|
</blockquote>
|
|
|
<p>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. OAuth is also not available on devices without Google
|
|
|
services, such as recent Huawei devices, in which case selecting an
|
|
|
account will fail.</p>
|
|
|
<p>The Gmail quick setup wizard won’t work if the Android account
|
|
|
manager doesn’t work or doesn’t support Google accounts, which is
|
|
|
typically the case if the account selection is being <em>canceled</em>
|
|
|
right away.</p>
|
|
|
<p>If you don’t want to use or can’t use an on-device Google account,
|
|
|
for example on recent Huawei devices, you can <del>either enable access
|
|
|
for “less secure apps” and use your account password (not advised)</del>
|
|
|
or enable two factor authentication and use an app specific password. To
|
|
|
use a password you can use the quick setup wizard and select <em>Other
|
|
|
provider</em>.</p>
|
|
|
<p><strong>Important</strong>: sometimes Google issues this alert:</p>
|
|
|
<p><em>[ALERT] Please log in via your web browser:
|
|
|
https://support.google.com/mail/accounts/answer/78754 (Failure)</em></p>
|
|
|
<p>This Google security check is triggered more often with <em>less
|
|
|
secure apps</em> enabled, less with an app password, and hardly when
|
|
|
using an on-device account (OAuth). You might see the error <em>OAUTH2
|
|
|
asked for more</em>, which basically says the connection is temporarily
|
|
|
blocked, until you confirm it is you.</p>
|
|
|
<p>Note that an app specific password is required when two factor
|
|
|
authentication is enabled. After enabling two factor authentication
|
|
|
there will be this error message:</p>
|
|
|
<p><em>[ALERT] Application-specific password required:
|
|
|
https://support.google.com/mail/accounts/answer/185833
|
|
|
(Failure)</em></p>
|
|
|
<p>The error message “<em>Authentication failed - Invalid
|
|
|
credentials</em>” or <em>Token refresh required</em> means that the
|
|
|
Android account manager was not able to refresh the access token, or
|
|
|
that getting an access token was not allowed, for example when the
|
|
|
account is a <a
|
|
|
href="https://support.google.com/families/answer/7101025">Family
|
|
|
Link</a> account, in which case you can use the Gmail app only. A common
|
|
|
cause for this problem is using a VPN, a firewall app or an ad blocker
|
|
|
which blocks internet access for the Android account manager. Please
|
|
|
make sure permissions were granted to the app via setup step 2. You can
|
|
|
try to workaround this issue by using the quick setup wizard <em>Gmail
|

<p>Firstly, Exchange <em>protocol</em> (EWS) is not the same as Exchange

<p>The Microsoft Exchange Web Services ™ (EWS) protocol <a

being phased out</a>. Microsoft stopped updating the EWS libraries <a
|
|
|
href="https://github.com/OfficeDev/ews-java-api">in 2016</a>. So, it
|

makes little sense to add this protocol anymore. Moreover, Microsoft

|
|
|
tools for this!</p>
|
|
|
<p>You can use a Microsoft Exchange account if it is accessible via

IMAP, which is almost always the case because all Exchange servers

support the standard IMAP protocol. See <a

|
|
<p>Identities represent email addresses you are sending <em>from</em>
|
|
|
via an email (SMTP) server.</p>
|
|
|
<p>Some providers allow you to have multiple aliases. The easiest way to
|
|
|
create an alias is to copy the main identity, and change the email
|
|
|
address and perhaps the (display) name. You should not change the
|
|
|
username! For this, please go to the settings via the navigation menu
|
|
|
(left side menu), tap on <em>Manual setup and account options</em>, tap
|
|
|
on <em>Identities</em>, long press the main identity, and select to copy
|
|
|
it.</p>
|
|
|
<p><strong>In many cases, an alias address must first be verified via
|
|
|
the website of the mail provider</strong></p>
|
|
|
<p>Alternatively, you can enable <em>Allow editing sender address</em>
|
|
|
in the advanced settings of an existing identity to edit the username
|
|
|
when composing a new message, if your provider allows this. Considering
|
|
|
the email address test@example.org you can use these special username
|
|
|
formats:</p>
|
|
|
<ul>
|
|
|
<li>“<em>+extra</em>” will result in the email address
|
|
|
“<em>test+extra@example.org</em>”</li>
|
|
|
<li>“<em><span class="citation" data-cites="extra">@extra</span></em>”
|
|
|
will result in the email address “<em>test@extra.example.org</em>”</li>
|
|
|
<li>“<em>Some name, username</em>” will result in the email address
|
|
|
“<em>Some name, <username@example.org></em>” (since version
|
|
|
1.2032)</li>
|
|
|
</ul>
|
|
|
<p>You can configure a default CC or BCC address in the advanced
|
|
|
identity settings.</p>
|
|
|
<p>FairEmail will automatically update the passwords of related
|
|
|
identities when you update the password of the associated account or a

|
|
|
<p>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.</p>
|
|
|
<p><br /></p>
|
|
|
<p><em>General</em></p>
|
|
|
<p>Please <a
|
|
|
href="https://en.wikipedia.org/wiki/Public-key_cryptography">see
|
|
|
here</a> about how public/private key encryption works.</p>
|
|
|
<p>Encryption in short:</p>
|
|
|
<ul>
|
|
|
<li><strong>Outgoing</strong> messages are encrypted with the
|
|
|
<strong>public key</strong> of the recipient</li>
|
|
|
<li><strong>Incoming</strong> messages are decrypted with the
|
|
|
<strong>private key</strong> of the recipient</li>
|
|
|
</ul>
|
|
|
<p>Signing in short:</p>
|
|
|
<ul>
|
|
|
<li><strong>Outgoing</strong> messages are signed with the
|
|
|
<strong>private key</strong> of the sender</li>
|
|
|
<li><strong>Incoming</strong> messages are verified with the
|
|
|
<strong>public key</strong> of the sender</li>
|
|
|
</ul>
|
|
|
<p>To sign/encrypt a message, just select the appropriate method in the
|
|
|
send dialog. The simplest way to show the send dialog (again) is to long
|
|
|
press the <em>Send</em> button in the bottom action bar. It might be
|
|
|
necessary to disable signing/encryption with the padlock icon in the top
|
|
|
action bar first, to prevent the select key dialog, etc. from being in
|
|
|
the way. The encryption method will be remembered for the selected
|
|
|
identity (at the top of the message editor).</p>
|
|
|
<p>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.</p>
|
|
|
<p>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 <em>Reset sign key</em>. 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.</p>
|
|
|
<p>In the encryption settings, you can select the default encryption
|
|
|
method (PGP or S/MIME), enable <em>Sign by default</em>, <em>Encrypt by
|
|
|
default</em> and <em>Automatically decrypt messages</em>, but be aware
|
|
|
that automatic decryption is not possible if user interaction is
|
|
|
required, like selecting a key or reading a security token.</p>
|
|
|
<p>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 tap on the
|
|
|
“close” padlock icon.</p>
|
|
|
<p><br /></p>
|
|
|
<p><em>PGP</em></p>
|
|
|
<p>You’ll need to install and configure <a
|
|
|
href="https://f-droid.org/en/packages/org.sufficientlysecure.keychain/">OpenKeychain</a>
|
|
|
first. FairEmail was tested with OpenKeychain version 5.4. Later
|
|
|
versions will most likely be compatible, but earlier versions might not
|
|
|
be.</p>
|
|
|
<p><strong>Important</strong>: 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.</p>
|
|
|
<p><strong>Important</strong>: if the OpenKeychain app cannot find a key
|
|
|
(anymore), you might need to reset a previously selected key. This can
|
|
|
be done by long pressing an identity in the list of identities
|
|
|
(Settings, tap Manual setup, tap Identities).</p>
|
|
|
<p><strong>Important</strong>: 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.</p>
|
|
|
<p><strong>Important</strong>: the OpenKeychain app reportedly needs
|
|
|
contacts permission to work correctly.</p>
|
|
|
<p><strong>Important</strong>: on some Android versions / devices it is
|
|
|
necessary to enable <em>Show popups while running in background</em> 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.</p>
|
|
|
<p>FairEmail will send the <a
|
|
|
href="https://autocrypt.org/">Autocrypt</a> 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. There is an encryption option to send
|
|
|
signed messages by default. Alternatively, this can enabled for a
|
|
|
specific identity in the advanced identity settings. Received Autocrypt
|
|
|
headers will be sent to the OpenKeychain app for storage on verifying a
|
|
|
signature or decrypting a message.</p>
|
|
|
<p>Although this shouldn’t be necessary for most email clients, you can
|
|
|
attach your public key to a message and if you use <em>.key</em> as
|
|
|
extension, the mime type will correctly be
|
|
|
<em>application/pgp-keys</em>.</p>
|
|
|
<p>All key handling is delegated to the OpenKey chain app for security
|
|
|
reasons. This also means that FairEmail does not store PGP keys.</p>
|
|
|
<p>Inline encrypted PGP in received messages is supported, but inline
|
|
|
PGP signatures and inline PGP in outgoing messages is not supported, see
|
|
|
<a
|
|
|
href="https://josefsson.org/inline-openpgp-considered-harmful.html">here</a>
|
|
|
about why not.</p>
|
|
|
<p>If you wish to verify a signature manually, check <em>Show inline
|
|
|
attachments</em> and save the files <em>content.asc</em> (the signed
|
|
|
content) and <em>signature.asc</em> (the digital signature). Install <a
|
|
|
href="https://www.gnupg.org/">GnuPG</a> on your preferred operating
|
|
|
system and execute this command:</p>
|
|
|
<p><code>gpg --verify signature.asc.pgp content.asc</code></p>
|
|
|
<p>Signed-only or encrypted-only messages are not a good idea, please
|
|
|
see here about why not:</p>

|
|
|
<p>Signed-only messages are supported, and encrypted-only messages are

supported since version 1.2053.</p>
|
|
|
<p>Common errors:</p>
|
|
|
<ul>
|
|
|
<li><em>No key</em>: there is no PGP key available for one of the listed
|
|
|
email addresses</li>
|
|
|
<li><em>No key found!</em>: the PGP key stored in the identity probably
|
|
|
doesn’t exist anymore. Resetting the key (see above) will probably fix
|
|
|
this problem.</li>
|
|
|
<li><em>Missing key for encryption</em>: 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.</li>
|
|
|
<li><em>Key for signature verification is missing</em>: the public key
|
|
|
for the sender is not available in the OpenKeychain app. This can also
|
|
|
be caused by Autocrypt being disabled in the encryption settings or by
|
|
|
the Autocrypt header not being sent.</li>
|
|
|
<li><em>OpenPgp error 0: null</em> / <em>OpenPgp error 0: General
|
|
|
error</em>: please check the key in the OpenKeychain app and make sure
|
|
|
there are no conflicting identities for the key and make sure the email
|
|
|
address exactly matches the key, including lower/upper case. Also, make
|
|
|
sure the key can be used to sign/encrypt and isn’t for
|
|
|
encrypting/signing only.</li>
|
|
|
<li><em>OpenPgp error 0: Encountered an error reading input data!</em>:
|
|
|
your public key has the <a
|
|
|
href="https://en.wikipedia.org/wiki/Authenticated_encryption">AEAD</a>
|
|
|
flag set, but the message was encrypted in the older MDC (Modification
|
|
|
Detection Code) mode by the sender. For example the Posteo email server
|
|
|
does this erroneously. Workaround: <a
|
|
|
href="https://github.com/keybase/keybase-issues/issues/4025#issuecomment-853933127">remove
|
|
|
the AEAD flag</a> from the key.</li>
|
|
|
</ul>
|
|
|
<p><strong>Important</strong>: if <em>Don’t keep activities</em> is
|
|
|
enabled in the Android developer options, FairEmail and the OpenKeychain
|
|
|
app cannot run at the same time, causing PGP operations to fail. If
|
|
|
needed, please <a
|
|
|
href="https://developer.android.com/studio/debug/dev-options#enable">see
|
|
|
here</a> about how to enable the developer options.</p>
|
|
|
<p><strong>Important</strong>: Android 8.1.0 on Tecno CF8 Camon 11 Pro
|
|
|
devices blocks communication between apps with the message
|
|
|
“<em>AutoStart limited</em>” in the system logcat. So, FairEmail (or any
|
|
|
other app) can’t communicate with the OpenKeychain app.</p>
|
|
|
<p><br /></p>
|
|
|
<p><em>S/MIME</em></p>
|
|
|
<p>Encrypting a message requires the public key(s) of the recipient(s).
|
|
|
Signing a message requires your private key.</p>
|
|
|
<p>Private keys are stored by Android and can be imported via the
|
|
|
Android advanced security settings (Encryption & credentials,
|
|
|
Install a certificate, VPN & app user certificate). There is a
|
|
|
shortcut (button) for this in the encryption settings for Android
|
|
|
version 10 and before. 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 <a
|
|
|
href="https://nokiamob.net/2019/08/10/a-bug-prevents-nokia-1-owners-from-unlocking-their-screen-even-with-right-pin-pattern/">read
|
|
|
this first</a>.</p>
|
|
|
<p><strong>Important</strong>: If Android doesn’t accept the password of
|
|
|
a certificate, it probably means it doesn’t support the certificate’s
|
|
|
encryption method. The solution is to convert the certificate like
|
|
|
this:</p>
|
|
|
<pre><code>openssl pkcs12 -nodes <your.p12 >certbag.pem
|
|
|
openssl pkcs12 -export -legacy -in certbag.pem >legacy.p12</code></pre>
|
|
|
<p>Note that .p12 and .pfx are interchangeable. You can find more
|
|
|
information about this issue <a
|
|
|
href="https://stackoverflow.com/questions/71872900/installing-pcks12-certificate-in-android-wrong-password-bug">here</a></p>
|
|
|
<p><br></p>
|
|
|
<p>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.</p>
|
|
|
<p>If you renewed a certificate, you should import the renewed
|
|
|
certificate and reset the key. This can be done by long pressing an
|
|
|
identity in the list of identities (Settings, tap Manual setup, tap
|
|
|
Identities).</p>
|
|
|
<p>Note that S/MIME signing with other algorithms than RSA is supported,
|
|
|
but be aware that other email clients might not support this. S/MIME
|
|
|
encryption is possible with asymmetric algorithms only, which means in
|
|
|
practice using RSA.</p>
|
|
|
<p>The default encryption method is PGP, but the last used encryption
|
|
|
method will be remembered for the selected identity for the next time.
|
|
|
You can long press on the send button to change the encryption method
|
|
|
for an identity. If you use both PGP and S/MIME encryption for the same
|
|
|
email address, it might be useful to copy the identity, so you can
|
|
|
change the encryption method by selecting one of the two identities. You
|
|
|
can long press an identity in the list of identities (via manual setup
|
|
|
in the main setup screen) to copy an identity.</p>
|
|
|
<p>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.</p>
|
|
|
<p>Public keys are stored by FairEmail and can be imported when
|
|
|
verifying a signature for the first time or via the encryption settings
|
|
|
(PEM or DER format).</p>
|
|
|
<p>FairEmail verifies both the signature and the complete certificate
|
|
|
chain.</p>
|
|
|
<p>Common errors:</p>
|
|
|
<ul>
|
|
|
<li><em>No certificate found matching targetContraints</em>: this likely
|
|
|
means you are using an old version of FairEmail</li>
|
|
|
<li><em>unable to find valid certification path to requested
|
|
|
target</em>: basically this means one or more intermediate or root
|
|
|
certificates were not found</li>
|
|
|
<li><em>Private key does not match any encryption keys</em>: the
|
|
|
selected key cannot be used to decrypt the message, probably because it
|
|
|
is the incorrect key</li>
|
|
|
<li><em>No private key</em>: no certificate was selected or no
|
|
|
certificate was available in the Android keystore</li>
|
|
|
<li><em>Memory allocation failed</em>: Android supports keys up to 4096
|
|
|
bits only (Android <a
|
|
|
href="https://issuetracker.google.com/issues/199605614">issue
|
|
|
199605614</a>)</li>
|
|
|
<li><em>message-digest attribute value does not match calculated
|
|
|
value</em>: the signature doesn’t match the message, possibly because
|
|
|
the message was changed, or because an incorrect or key was used</li>
|
|
|
</ul>
|
|
|
<p>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 “<a
|
|
|
href="https://tools.ietf.org/html/rfc5280#section-4.2.1.3">keyCertSign</a>”.
|
|
|
Certificates found in the Android key store are marked with
|
|
|
“Android”.</p>
|
|
|
<p>A valid chain looks like this:</p>
|
|
|
<pre><code>Your certificate > zero or more intermediate certificates > CA (root) certificate marked with "Android"</code></pre>
|
|
|
<p>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.</p>

|
|
|
<p>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 <em>Search email</em> in the copy/paste popup menu.</p>
|
|
|
<p>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.</p>
|
|
|
<p>Messages will be searched for on the device first. You can download
|
|
|
more messages on the device via the three-dots overflow menu in the
|
|
|
start screen. 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.</p>
|
|
|
<p>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.</p>
|

|
<p>The POP3 protocol doesn’t support searching on the server at all.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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. Since version 1.1888 a popup
|
|
|
message will be shown and the search will automatically be retried
|
|
|
without searching in the message text.</p>
|
|
|
<p>It is possible to use Gmail search operators by prefixing a search
|
|
|
command with <em>raw:</em>. 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 <a
|
|
|
href="https://support.google.com/mail/answer/7190">see here</a> for the
|
|
|
possible search operators. For example:</p>
|
|
|
<p><code>raw:larger:10M</code></p>
|
|
|
<p>Searching through a large number of messages on the device is not
|
|
|
very fast because of two limitations:</p>
|
|
|
<ul>
|
|
|
<li><a href="https://www.sqlite.org/">sqlite</a>, the database engine of
|
|
|
Android has a record size limit, preventing message texts from being
|
|
|
stored in the database</li>
|
|
|
<li>Android apps get only limited memory to work with, even if the
|
|
|
device has plenty memory available</li>
|
|
|
</ul>
|
|
|
<p>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.</p>
|
|
|
<p>In the <em>miscellaneous settings</em> you can enable <em>Build
|
|
|
search index</em> 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 in all message parts, so
|
|
|
searching for partial text and searching in specific messages parts
|
|
|
(from, subject, text, etc) is not possible.</p>
|
|
|
<p>Note that only messages for which the message text was downloaded
|
|
|
will be indexed. In the connection settings can be configured up to
|
|
|
which size messages texts will be downloaded automatically when using a
|
|
|
metered connection (generally mobile data or paid WiFi). In the folder
|
|
|
properties (long press on a folder in the folder list of an account)
|
|
|
downloading of messages texts can be enabled/disabled.</p>
|
|
|
<p>Searching using the search index is by default AND, so searching for
|
|
|
<em>apple orange</em> will search for apple AND orange. Words separated
|
|
|
by commas result in searching for OR, so for example <em>apple,
|
|
|
orange</em> will search for apple OR orange. Both can be combined, so
|
|
|
searching for <em>apple, orange banana</em> will search for apple OR
|
|
|
(orange AND banana). Using the search index is a pro feature.</p>
|
|
|
<p>Since version 1.1315 it is possible to use search expressions like
|
|
|
this:</p>
|
|
|
<pre><code>apple +banana -cherry ?nuts</code></pre>
|
|
|
<p>This will result in searching in the subject or text (only) like
|
|
|
this:</p>
|
|
|
<pre><code>("apple" AND "banana" AND NOT "cherry") OR "nuts"</code></pre>
|
|
|
<p>Since version 1.1980 it is possible to use these prefixes as a search
|
|
|
expression:</p>
|
|
|
<pre><code>from:<email address>
|
|
|
to:<email address>
|
|
|
cc:<email address>
|
|
|
bcc:<email address>
|
|
|
keyword:<keyword></code></pre>
|
|
|
<p>There should be no space between the prefix and the search term,
|
|
|
which will be applied as an AND-condition.</p>
|
|
|
<p>Only AND conditions (+) and NOT conditions (-) can be used for
|
|
|
on-device searching (since version 1.1981). If you try to use other
|
|
|
search expressions, you get the error <em>Select a folder for a complex
|
|
|
search</em>, which means that a folder in an account’s folder list must
|
|
|
be selected in order to perform the search on the server.</p>
|
|
|
<p>Since version 1.1733 it is possible to save searches, which means
|
|
|
that a named entry in the navigation menu will be created to repeat the
|
|
|
same search later. You can save a search after searching by tapping on
|
|
|
the save button in the top action bar. After repeating a search there
|
|
|
will be a delete button at the same place to delete a saved search
|
|
|
again. A saved search might be useful to quickly search for starred
|
|
|
messages, or for messages from a specific email address, etc.</p>
|
|
|
<p>Using the search index is a pro feature.</p>

<p>Possible causes of messages not being synchronized (sent or received)

are:</p>

<ul>

|
|
|
<li>A memory management app stopped the synchronization service</li>

<p>If there are any error messages, please see <a href="#faq22">this

|
|
|
<p>On some devices, where there are lots of applications competing for

|
|
|
resort.</p>
|
|
|
<p>Some Android versions, especially those of Samsung, OnePlus, Huawei

<p><strong>FairEmail is basically free to use</strong> and only some

advanced features need to be purchased.</p>
|
|
|
<p><strong>FairEmail ist grundsätzlich kostenlos</strong> und nur einige

|
|
|
<p><strong>FairEmail est au fond gratuit</strong> et seulement quelques
|
|

|
<p>Please see the Play store description of the app or <a

of pro features.</p>
|
|
|
<p>The right question is “<em>why are there so many taxes and
|
|
|
fees?</em>”:</p>
|
|
|
<ul>
|
|
|
<li>VAT: 25 % (depending on your country)</li>
|
|
|
<li>Google fee: 15-30 %</li>
|
|
|
<li>Income tax: 50 %</li>
|
|
|
<li><sub>Paypal fee: 5-10 % depending on the country/amount</sub></li>
|
|
|
</ul>
|
|
|
<p>So, what is left for the developer is just a fraction of what you
|
|
|
pay.</p>
|
|
|
<p>Also note that most free apps will appear not to be sustainable in
|
|
|
the end, whereas FairEmail is properly maintained and supported, and
|
|
|
that free apps may have a catch, like sending privacy sensitive
|
|
|
information to the internet. There are no privacy violating ads in the
|
|
|
app either.</p>
|
|
|
<p>I have been working on FairEmail almost every day for more than four
|
|
|
years, so I think the price is more than reasonable. For this reason

there won’t be discounts either.</p>

<p>Before Android 8 Oreo: there is an advanced option in the

notification settings of the app for this.</p>
|
|
|
<p>Android 8 Oreo and later: please see <a
|
|
|
href="https://developer.android.com/training/notify-user/channels">here</a>
|
|
|
about how to configure notification channels. You can use the button
|
|
|
<em>Default channel</em> in the notification settings of the app to
|
|
|
directly go to the right Android notification channel settings.</p>
|
|
|
<p>Note that apps cannot change notification settings, including the
|
|
|
notification light setting, on Android 8 Oreo and later anymore.</p>
|
|
|
<p>Sometimes it is necessary to disable the setting <em>Show message
|
|
|
preview in notifications</em> or to enable the settings <em>Show
|
|
|
notifications with a preview text only</em> to workaround bugs in
|
|
|
Android. This might apply to notification sounds and vibrations too.</p>
|
|
|
<p>Setting a light color before Android 8 is not supported and on
|
|
|
Android 8 and later not possible.</p>
|
|
|
<p>Some apps create a notification channel for each selectable color and
|
|
|
let you (indirectly) select these channels when selecting a color. Since
|
|
|
FairEmail uses notification channels for configurable notification
|
|
|
properties for accounts, folders and senders (<a href="#faq145">see this
|
|
|
FAQ</a>), this is not a feasible solution for FairEmail because it would
|
|

result in an unmanageable number of notification channels.</p>

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.</p>

<p>If needed, you can update a password in the account settings:
|
|
|
navigation menu (left side menu), tap <em>Settings</em>, tap <em>Manual
|
|
|
setup</em>, tap <em>Accounts</em> and tap on the account. Changing the
|
|
|
account password will in most cases automatically change the password of
|
|
|
related identities too. If the account was authorized with OAuth via the
|
|
|
quick setup wizard instead of with a password, you can run the quick
|
|
|
setup wizard again and tick <em>Authorize existing account again</em> to
|
|
|
authenticate the account again. Note that this requires a recent version
|
|
|
of the app.</p>
|
|
|
<p>The error <em>… Too many bad auth attempts …</em> likely means that
|
|
|
you are using a Yahoo account password instead of an app password.
|
|
|
Please see <a href="#faq88">this FAQ</a> about how to set up a Yahoo
|
|
|
account.</p>
|
|
|
<p>The message <em>… +OK …</em> likely means that a POP3 port (usually
|
|
|
port number 995) is being used for an IMAP account (usually port number
|
|
|
993).</p>
|
|
|
<p>The errors <em>… invalid greeting …</em>, <em>… requires valid
|
|
|
address …</em> and <em>… Parameter to HELO does not conform to RFC
|
|
|
syntax …</em> can likely be solved by changing the advanced identity
|
|
|
setting <em>Use local IP address instead of host name</em>.</p>
|
|
|
<p>The error <em>… Couldn’t connect to host …</em> 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. Some devices have a firewall, which you
|
|
|
can access like this:</p>
|
|
|
<p>Android <em>Settings, Data usage, Three-dots overflow menu, Data
|
|
|
usage control</em></p>
|
|
|
<p>The error <em>… Connection refused …</em> (ECONNREFUSED) means that
|
|
|
the email server or something between the email server and the app, like
|
|
|
a firewall, actively refused the connection.</p>
|
|
|
<p>The error <em>… Network unreachable …</em> means that the email
|
|
|
server was not reachable via the current internet connection, for
|
|
|
example because internet traffic is restricted to local traffic
|
|
|
only.</p>
|
|
|
<p>The error <em>… Host is unresolved …</em>, <em>… Unable to resolve
|
|
|
host …</em> or <em>… No address associated with hostname …
|
|
|
android_getaddrinfo failed: EAI_NODATA</em> 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) <a
|
|
|
href="https://en.wikipedia.org/wiki/Domain_Name_System">DNS</a> server.
|
|
|
An incorrect Android private DNS network setting can cause this too.</p>
|
|
|
<p>The error <em>… Software caused connection abort …</em> 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.</p>
|
|
|
<p>The errors <em>… BYE Logging out …</em>, <em>… Connection reset
|
|
|
…</em> 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.</p>
|
|
|
<p>The error <em>… Connection closed by peer …</em> means that the email
|
|
|
server actively closed the connection. This might be caused by a not
|
|
|
updated Exchange server, see <a
|
|
|
href="https://blogs.technet.microsoft.com/pki/2010/09/30/sha2-and-windows/">here</a>

for more information.</p>
|
|
|
<p>The errors <em>… Read error …</em> (sometimes combined with
|
|
|
<em>BAD_DECRYPT</em> / <em>DECRYPTION_FAILED_OR_BAD_RECORD_MAC</em>),
|
|
|
<em>… Write error …</em>, <em>… Read timed out …</em>, <em>… Broken pipe
|
|
|
…</em> mean that the email server is not responding anymore or that the
|
|
|
internet connection is bad.</p>
|
|
|
<p><a name="connectiondropped"></a> The error <em>… Connection dropped
|
|
|
by server? …</em> means that the email server unexpectedly terminated
|
|
|
the connection. This sometimes happen when there were too many
|
|
|
(simultaneous) connections in a too short time or when a wrong password
|
|
|
was used too often. 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 <a href="#faq23">this FAQ</a>
|
|
|
about how you can reduce the number of connections.</p>
|
|
|
<p>The error <em>… Unexpected end of zlib input stream …</em> means that
|
|
|
not all data was received, possibly due to a bad or interrupted
|
|
|
connection.</p>
|
|
|
<p>The error <em>… connection failure …</em> could indicate <a
|
|
|
href="#faq23">Too many simultaneous connections</a>.</p>
|
|
|
<p>The warning <em>… Unsupported encoding …</em> means that the
|
|
|
character set of the message is unknown or not supported. FairEmail will
|
|
|
assume ISO-8859-1 (Latin1), which will in most cases result in showing
|
|
|
the message correctly.</p>
|
|
|
<p>The error <em>… Login Rate Limit Hit …</em> means that there were too
|
|
|
many login attempts with an incorrect password. Please double check your
|
|
|
password or authenticate the account again with the quick setup wizard
|
|
|
(OAuth only).</p>
|
|
|
<p>The error <em>… NO mailbox selected READ-ONLY …</em> indicates <a
|
|
|
href="https://sebastian.marsching.com/wiki/Network/Zimbra#Mailbox_Selected_READ-ONLY_Error_in_Thunderbird">this
|
|
|
Zimbra problem</a>.</p>
|
|
|
<p>The Outlook specific error <em>… Command Error. 10 …</em> probably
|
|
|
means that the OAuth token expired or was invalidated. Authenticating
|
|
|
the account again with the quick setup wizard will probably resolve this
|
|
|
condition. Another possible cause is a bug in an older Exchange version,
|
|
|
please <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=886261">see
|
|
|
here</a>. In this case the system administrator needs to update the

<p>Please <a href="#faq4">see here</a> for the errors <em>… Untrusted …
|
|

|
|
|
<p>The error <em>… connect failed: EACCES (Permission denied) …</em>
|
|
|
means that <em>Restrict data usage</em> was disabled in the Android MIUI
|
|
|
app settings for FairEmail. On Samsung, and possible other devices, also
|
|
|
check: Android settings > Battery > Battery manager / Unmonitored
|
|
|
apps.</p>
|
|
|
<p>Possible causes are:</p>
|
|
|
<ul>
|
|
|
<li>A firewall or router is blocking connections to the server</li>
|
|
|
<li>The host name or port number is invalid</li>
|
|
|
<li>There are problems with the internet connection</li>
|
|
|
<li>There are problems with resolving domain names (Yandex: try to
|
|
|
disable private DNS in the Android settings)</li>
|
|
|
<li>The email server is refusing to accept (external) connections</li>
|
|
|
<li>The email server is refusing to accept a message, for example
|
|
|
because it is too large or contains unacceptable links</li>
|
|
|
<li>There are too many connections to the server, see also the next
|
|
|
question</li>
|
|
|
</ul>
|
|
|
<p>Many public Wi-Fi networks block outgoing email to prevent spam.
|
|
|
Sometimes you can workaround this by using another SMTP port. See the
|
|
|
documentation of the provider for the usable port numbers.</p>
|
|
|
<p>If you are using a <a
|
|
|
href="https://en.wikipedia.org/wiki/Virtual_private_network">VPN</a>,
|
|
|
the VPN provider might block the connection because it is too
|
|
|
aggressively trying to prevent spam. Similarly, the email server might
|
|
|
block connections via a VPN because it was misused for sending spam.
|
|
|
Some VPN providers have “cleaner” IP addresses than others, so switching
|
|
|
to another VPN provider might be useful. Note that <a
|
|
|
href="https://fi.google.com/">Google Fi</a> is using a VPN too.</p>
|
|
|
<p>The error ‘<em>You must use stronger authentication such as AUTH or
|
|
|
APOP to connect to this server</em>’ can be fixed by enabling debug mode
|
|
|
(last option in the miscellaneous settings tab page), and in the debug
|
|
|
panel that appears enabling the APOP option. After that, debug mode can
|
|
|
be disabled again.</p>

<p>The authorization of Gmail accounts setup with the quick wizard needs

|
|
to be periodically refreshed via the <a
|
|
|
href="https://developer.android.com/reference/android/accounts/AccountManager">Android
|
|
|
account manager</a>. This requires contact/account permissions and
|
|
|
internet connectivity.</p>
|
|
|
<p>In case of errors it is possible to authorize/restore a Gmail account
|
|
|
again via the Gmail quick setup wizard.</p>
|
|
|
<p>The error <em>… Authentication failed … Account not found …</em>
|
|
|
means that a previously authorized Gmail account was removed from the
|
|
|
device.</p>
|
|
|
<p>The errors <em>… Authentication failed … No token …</em> means that
|
|
|
the Android account manager failed to refresh the authorization of a
|
|
|
Gmail account.</p>
|
|
|
<p>The error <em>… Authentication failed … network error …</em> means
|
|
|
that the Android account manager was not able to refresh the

authorization of a Gmail account due to problems with the internet
|
|
|
connection</p>
|
|
|
<p>The error <em>… Authentication failed … Invalid credentials …</em>
|
|
|
could be caused by changing the account password or by having revoked

|
the required account/contacts permissions. In case the account password
|
|
|
was changed, you’ll need to authenticate the Google account in the

you can start the Gmail quick setup wizard to grant the required
|
|
|
permissions again (you don’t need to setup the account again).</p>
|
|
|
<p>The eror <em>… ServiceDisabled …</em> might be caused by enrolling in

|
|
|
<p><em>General</em></p>
|
|
|
<p>Alerts are warning messages sent by email servers.</p>
|
|
|
<p><em>Too many simultaneous connections</em> or <em>Maximum number of
|
|
|
connections exceeded</em></p>
|
|
|
<p>This alert will be sent when there are too many folder connections
|
|
|
for the same email account at the same time.</p>
|
|
|
<p>Possible causes are:</p>
|
|
|
<ul>
|
|
|
<li>There are multiple email clients connected to the same account</li>
|
|
|
<li>The same email client is connected multiple times to the same
|
|
|
account</li>
|
|
|
<li>Previous connections were terminated abruptly for example by
|
|
|
abruptly losing internet connectivity</li>
|
|
|
</ul>
|
|
|
<p>First try to wait some time to see if the problem resolves itself,
|
|
|
else:</p>
|
|
|
<ul>
|
|
|
<li>either switch to periodically checking for messages in the receive
|
|
|
settings, which will result in opening folders one at a time</li>
|
|
|
<li>or set some folders to poll instead of synchronize (long press
|
|
|
folder in the folder list, edit properties)</li>
|
|
|
</ul>
|
|
|
<p>An easy way to configure periodically checking for messages for all
|
|
|
folders except the inbox is to use <em>Apply to all …</em> in the
|
|
|
three-dots menu of the folder list and to tick the bottom two advanced
|
|
|
checkboxes.</p>
|
|
|
<p>The maximum number of simultaneous folder connections for Gmail is
|
|
|
15, so you can synchronize at most 15 folders simultaneously on
|
|
|
<em>all</em> your devices at the same time. For this reason Gmail
|
|
|
<em>user</em> 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 <em>Edit properties</em>. See <a
|
|
|
href="https://support.google.com/mail/answer/7126229">here</a> for
|
|
|
details.</p>
|
|
|
<p>When using a Dovecot server, you might want to change the setting <a
|
|
|
href="https://doc.dovecot.org/settings/dovecot_core_settings/#mail-max-userip-connections">mail_max_userip_connections</a>.</p>
|
|
|
<p>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.</p>

<p>When a menu item to select/open/save a file is disabled (dimmed) or
|
|
|
when you get the message <em>Storage access framework not
|
|
|
available</em>, the <a
|
|
|
href="https://developer.android.com/guide/topics/providers/document-provider">storage
|
|
|
access framework</a>, 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).</p>
|
|
|
<p>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 <em>all</em> files.
|
|
|
Moreover, recent Android versions disallow access to all files for apps,
|
|
|
except, under specific conditions, for file managers.</p>
|
|
|
<p>The storage access framework is provided by the package
|
|
|
<em>com.android.documentsui</em>, which is visible as <em>Files</em> app
|
|
|
on some Android versions (notably OxygenOS).</p>
|
|
|
<p>You can enable the storage access framework (again) with this adb
|
|
|
command:</p>
|
|
|
<pre><code>pm install -k --user 0 com.android.documentsui</code></pre>
|
|
|
<p>Alternatively, you might be able to enable the <em>Files</em> app
|
|
|
again using the Android app settings.</p>

<p>Most providers accept validated addresses only when sending messages
|
|
|
to prevent spam.</p>
|
|
|
<p>For example Google modifies the message headers like this for
|
|
|
<em>unverified</em> addresses:</p>
|
|
|
<pre><code>From: Somebody <somebody@example.org>
|
|
|
X-Google-Original-From: Somebody <somebody+extra@example.org></code></pre>
|
|
|
<p>This means that the edited sender address was automatically replaced
|
|
|
by a verified address before sending the message.</p>

<p>Note that this is independent of receiving messages.</p>

|
|
|
<p>Identities are as expected matched by account. For incoming messages
|
|
|
the <em>to</em>, <em>cc</em>, <em>bcc</em>, <em>from</em> and
|
|
|
<em>(X-)delivered/envelope/original-to</em> addresses will be checked
|
|
|
(in this order) and for outgoing messages (drafts, outbox and sent) only
|
|
|
the <em>from</em> addresses will be checked. Equal addresses have
|
|
|
precedence over partially matching addresses, except for
|
|
|
<em>delivered-to</em> addresses.</p>
|
|
|
<p>The matched address will be shown as <em>via</em> in the addresses
|
|
|
section of received messages (between the message header and message
|
|
|
text).</p>
|
|
|
<p>Note that identities need to be enabled to be able to be matched and
|
|
|
that identities of other accounts will not be considered.</p>
|
|
|
<p>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.</p>
|
|
|
<p>It is possible to configure a <a
|
|
|
href="https://en.wikipedia.org/wiki/Regular_expression">regex</a> in the
|
|
|
identity settings to match <strong>the username</strong> of an email
|
|
|
address (the part before the @ sign).</p>
|
|
|
<p>Note that the domain name (the parts after the @ sign) always needs
|
|
|
to be equal to the domain name of the identity. Since version 1.1640 it
|
|
|
is possible to match the full email address with a regex, which can be
|
|
|
useful for matching alias domain names.</p>
|
|
|
<p>If you want to match a catch-all email address, this regex is usually
|
|
|
fine, provided all usernames for the domain are yours:</p>
|
|
|
<pre><code>.*</code></pre>
|
|
|
<p>The username of a message being replied to will be used as the
|
|
|
default username when editing of usernames is enabled in the advanced
|
|
|
identity settings.</p>
|
|
|
<p>Please see <a href="#faq9">this FAQ</a> about editing the email
|
|
|
address when composing a message.</p>
|
|
|
<p>If you want to <em>not</em> match specific addresses, you can use
|
|
|
something like this:</p>
|
|
|
<pre><code>^(?!marcel$|johanna$).*</code></pre>
|
|
|
<p>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:</p>
|
|
|
<ul>
|
|
|
<li>Identity: abc@example.com; regex: <strong>(?i)abc</strong></li>
|
|
|
<li>Identity: xyz@example.com; regex: <strong>(?i)xyz</strong></li>
|
|
|
<li>Identity: main@example.com; regex:
|
|
|
<strong>^(?i)((?!abc|xyz).)*$</strong></li>
|
|
|
</ul>
|
|
|
<p>You can test a regex <a href="https://regexr.com/">here</a>.</p>
|
|
|
<p>Matched identities can be used to color code messages.</p>
|
|
|
<p>The identity color takes precedence over the folder and account
|
|
|
color. This means that the color of the color stripe will be determined
|
|
|
by first checking if there is a color set for the ‘via’ (matched)
|
|
|
identity, and after that if there is a color set for the folder
|
|
|
containing the message, and finally if there is a color set for the
|
|
|
account the message belongs to.</p>
|
|
|
<p>Setting identity colors is a pro feature.</p>

<p>Recent Android versions by default report <em>app usage</em> as a

|
|
percentage in the Android battery settings screen. <strong>Confusingly,
|
|
|
<em>app usage</em> is not the same as <em>battery usage</em> and is not
|
|
|
even directly related to battery usage!</strong> 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:</p>
|

|
<p><em>Android settings</em>, <em>Battery</em>, three-dots menu
|
|
|
<em>Battery usage</em>, three-dots menu <em>Show full device

|

|
|
|
<p>Alternatively: tap on the <em>App settings</em> button in the main
|
|
|
settings screen of the app and tap on <em>Battery</em>.</p>
|
|
|
<p>As a rule of thumb, the battery usage should be below or in any case
|
|
|
not be much higher than <em>Mobile network standby</em> for one account
|
|
|
with a stable network connection. If this isn’t the case, please turn on
|
|
|
<em>Auto optimize</em> in the receive settings tab page. If this doesn’t

|
|
|
<p>It is inevitable that synchronizing messages will use battery power
|
|
|
because it requires network access and accessing the messages’ database.
|
|
|
Since the app needs to wait for responses of the email server, which
|
|
|
requires the processor (CPU) to be active, slower email servers will
|
|
|
result in more battery usage.</p>
|
|
|
<p>If you are comparing the battery usage of FairEmail with another
|
|
|
email client, please make sure the other email client is set up
|
|
|
similarly. For example, comparing always sync (push messages) and
|
|
|
(infrequent) periodic checking for new messages is not a fair
|
|
|
comparison.</p>
|
|
|
<p>If you are comparing the battery usage of FairEmail with an app like
|
|
|
Whatsapp, please understand that most apps use <a
|
|
|
href="https://firebase.google.com/docs/cloud-messaging">Firebase Cloud
|
|
|
Messaging</a> (FCM) for push messages, which means that no battery usage
|
|
|
will be contributed to an app for push messages, but instead to the
|
|
|
Google Play Services system component. Apart from the privacy concerns,
|
|
|
it is not possible to use FCM for email because email servers do not
|
|
|
support FCM. The only way would be to download all your messages to a
|
|
|
third-party server first and use FCM to push notifications to the app.
|
|
|
The privacy and security implications would be significant, though.</p>
|
|
|
<p>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 <a
|
|
|
href="https://tools.ietf.org/html/rfc2177">the standard</a> 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.</p>
|
|
|
<p>If you know that the connection (reception) is bad, it might be
|
|
|
worthwhile to decrease the timeout value in the connection-settings tab
|
|
|
page to 10–20 seconds, so that the app discovers earlier that no
|
|
|
connection is possible, so that the mechanism as described in <a
|
|
|
href="#faq123">this FAQ</a> is used faster.</p>
|
|
|
<p><a href="https://dontkillmyapp.com/">On some devices</a> it is
|
|
|
necessary to <em>disable</em> 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!</p>
|
|
|
<p>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 <em>Edit
|
|
|
properties</em> to access this setting.</p>
|
|
|
<p>If you have at least once a day internet connectivity, it is
|
|
|
sufficient to synchronize messages just for one day.</p>
|
|
|
<p>Note that you can set the number of days to <em>keep</em> messages
|
|
|
for to a higher number than to <em>synchronize</em> messages for. You
|
|
|
could for example initially synchronize messages for a large number of
|
|
|
days and after this has been completed reduce the number of days to
|
|
|
synchronize messages, but leave the number of days to keep messages.
|
|
|
After decreasing the number of days to keep messages, you might want to
|
|
|
run the cleanup in the miscellaneous settings to remove old files.</p>
|
|
|
<p>In the receive settings tab page 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.</p>
|
|
|
<p>Disabling the folder option <em>Automatically download message texts
|
|
|
and attachments</em> 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.</p>
|
|
|
<p>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).</p>
|
|
|
<p>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 tab page.</p>
|
|
|
<p>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
|
|
|
deleted from the server are still visible in FairEmail, you can save
|
|
|
some network and battery usage by disabling this in the receive settings
|
|
|
tab page.</p>
|
|
|
<p>Some providers don’t follow the IMAP standard and <a
|
|
|
href="https://datatracker.ietf.org/doc/html/rfc3501#section-5.4">don’t
|
|
|
keep connections open</a> long enough, forcing FairEmail to reconnect
|
|
|
often, causing extra battery usage. You can inspect the <em>Log</em> via
|
|
|
the main navigation menu to check if there are frequent reconnects
|
|
|
(connection closed/reset, read/write error/timeout, etc.). You can work
|
|
|
around 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.</p>
|
|
|
<p>Some providers send every two minutes something like ‘<em>Still
|
|
|
here</em>’ resulting in network traffic and your device to wake up and
|
|
|
causing unnecessary extra battery usage. You can inspect the
|
|
|
<em>Log</em> via the main navigation menu to check if your provider is
|
|
|
doing this. If your provider is using <a
|
|
|
href="https://www.dovecot.org/">Dovecot</a> as IMAP server, you could
|
|
|
ask your provider to change the <a
|
|
|
href="https://wiki.dovecot.org/Timeouts">imap_idle_notify_interval</a>
|
|
|
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 switching to periodically instead of continuous
|
|
|
synchronization. You can change this in the receive settings tab
|
|
|
page.</p>
|
|
|
<p>If you got the message, <em>This provider does not support push
|
|
|
messages</em> while configuring an account, consider switching to a
|
|
|
modern provider which supports push messages (IMAP IDLE) to reduce
|
|
|
battery usage.</p>
|
|
|
<p>If your device has an <a
|
|
|
href="https://en.wikipedia.org/wiki/AMOLED">AMOLED</a> screen, you can
|
|
|
save battery usage while viewing messages by switching to the black
|
|
|
theme.</p>
|
|
|
<p>If auto optimize in the receive settings tab page is enabled, an
|
|
|
account will automatically be switched to periodically checking for new
|
|
|
messages when the email server:</p>
|

|
|
<p>You can reduce the data usage basically in the same way as reducing
|
|
|
battery usage, see the previous question for suggestions.</p>
|
|
|
<p>It is inevitable that data will be used to synchronize messages.</p>
|
|
|
<p>If the connection to the email server is lost, FairEmail will always
|
|
|
synchronize the messages again to make sure no messages were missed. If
|
|
|
the connection is unstable, this can result in extra data usage. In this
|
|
|
case, it is a good idea to decrease the number of days to synchronize
|
|
|
messages to a minimum (see the previous question) or to switch to
|
|
|
periodically synchronizing of messages (receive settings).</p>
|
|
|
<p>To reduce data usage, you could change these advanced receive
|
|
|
settings:</p>
|
|
|
<ul>
|
|
|
<li>Check if old messages were removed from the server: disable</li>
|
|
|
<li>Synchronize (shared) folder list: disable</li>
|
|
|
</ul>
|
|
|
<p>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.</p>
|
|
|
<p>You could enable to download only plain text only parts, but all
|
|
|
messages will be without formatting (styling), and besides that, a plain
|
|
|
text only part is not always sent, and worse, it is sometimes only a
|
|
|
part of the message text, containing HTML and CCS.</p>
|
|
|
<p>In case of POP3, you can reduce the maximum number of messages to
|
|
|
download.</p>

|
Translate</a></p>
|
|
|
<p>There are several possible causes, so please read to the end of this
|
|
|
answer.</p>
|
|
|
<p>The error ‘<em>Handshake failed … WRONG_VERSION_NUMBER …</em>’ 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.</p>
|
|
|
<p>Most providers provide encrypted connections using different ports,
|
|
|
typically port 993 (IMAP) and port 465/587 (SMTP).</p>
|
|
|
<p>If your provider doesn’t support encrypted connections, you should
|
|
|
ask to make this possible. If this isn’t an option, you could enable
|
|
|
<em>Allow insecure connections</em> both in the advanced settings AND
|
|
|
the account/identity settings.</p>
|
|
|
<p>See also <a href="#faq4">this FAQ</a>.</p>
|
|
|
<p>The error ‘<em>Handshake failed … SSLV3_ALERT_ILLEGAL_PARAMETER
|
|
|
…</em>’ 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.</p>
|
|
|
<p>The error ‘<em>Handshake failed … HANDSHAKE_FAILURE_ON_CLIENT_HELLO
|
|
|
…</em>’ might be caused by the provider still using RC4, which isn’t
|
|
|
supported since <a
|
|
|
href="https://developer.android.com/about/versions/nougat/android-7.0-changes.html#tls-ssl">Android
|
|
|
7</a> anymore.</p>
|
|
|
<p>The error ‘<em>Handshake failed SSL handshake terminated …
|
|
|
SSLV3_ALERT_HANDSHAKE_FAILURE … HANDSHAKE_FAILURE_ON_CLIENT_HELLO</em>’
|
|
|
can be caused by <a
|
|
|
href="https://issuetracker.google.com/issues/37122132">this Android 7.0
|
|
|
bug</a>. This can unfortunately not be fixed by FairEmail.</p>
|
|
|
<p>The error ‘<em>Handshake failed … UNSUPPORTED_PROTOCOL or
|
|
|
TLSV1_ALERT_PROTOCOL_VERSION or SSLV3_ALERT_HANDSHAKE_FAILURE …</em>’
|
|
|
might be caused by enabling <strong>hardening connections</strong> or
|
|
|
<strong>Bouncy Castle</strong> in the connection settings tab page, or
|
|
|
by Android not supporting older protocols anymore, like SSLv3 and
|
|
|
TLSv1.</p>
|
|
|
<p>The error ‘<em>javax.net.ssl.SSLHandshakeException: Read error: …
|
|
|
CERT_LENGTH_MISMATCH</em>’ means that there is something wrong with the
|
|
|
email server setup. Try to switch to port 993 (IMAP) or 465 (SMTP) with
|
|
|
SSL/TLS.</p>
|
|
|
<p>Android 8 Oreo and later <a
|
|
|
href="https://developer.android.com/about/versions/oreo/android-8.0-changes#security-all">do
|
|
|
not support</a> 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). Since version 1.2121 the Bouncy Castle
|
|
|
secure socket provider (<a
|
|
|
href="https://en.wikipedia.org/wiki/Java_Secure_Socket_Extension">JSSE</a>)
|
|
|
is bundled. Enabling this socket provider in the connection-settings tab
|
|
|
and enabling ‘<em>Allow insecure connections</em>’ in the
|
|
|
account/identity settings <em>might</em> solve this problem.</p>
|
|
|
<p>The error ‘<em>javax.net.ssl.SSLHandshakeException: Read error: …
|
|
|
TLSV1_ALERT_INTERNAL_ERROR</em>’ means that Android and the email server
|
|
|
share no common protocol versions and/or common ciphers.</p>

<p>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 <em>An outdated app sent a file path instead of a file
|
|
|
stream</em> if a file name instead of a file stream is being shared with
|
|
|
FairEmail because FairEmail cannot randomly open files.</p>
|
|
|
<p>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 <a

<p>There is no reliable way to know if an account connection was

while the account connection was terminated forcefully too often can

|

result in problems like <a href="#faq23">too many simultaneous

|
<p>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.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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.</p>

<p>If you want to use preformatted text, like <a

<p>You can add images to a message in two ways:</p>

<p>If you disabled the bottom action bar, you can enable it again via

<p>An attachment will always be sent as-is. An image can be added as

|
|
|
<p>Images will be scaled down using whole number factors to reduce
|
|
|
memory usage and to retain the image quality. Scaled images will be

|
|
saved with a compression ratio of 90 %.</p>
|
|
|
<p>If the image options do not appear, you can enable them again via the

|
|
|
<p>You can edit rules by long pressing a folder in the folder list of an
|
|
|
account (tap the account name in the navigation/side menu).</p>
|
|
|
<p>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 <em>Execute now</em>.</p>
|
|
|
<p>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.</p>
|
|
|
<p>You can disable a rule and you can stop processing other rules after
|
|
|
a rule has been executed, which can be used to create a <em>not</em>
|
|
|
condition.</p>
|
|
|
<p>Since version 1.2061 rules can be part of a named group. Group names
|
|
|
will be displayed in the list of rules. If a rule is part of a group,
|
|
|
stop processing means stop processing the group.</p>
|
|
|
<p>Since version 1.2018 there is a rule option to run rules daily on
|
|
|
messages (around 1:00am) older than xxx.</p>
|
|
|
<p>The following rule conditions are available:</p>
|
|
|
<ul>
|
|
|
<li>Sender (from, reply-to) contains or sender is contact</li>
|
|
|
<li>Recipient (to, cc, bcc) contains</li>
|
|
|
<li>Subject contains</li>
|
|
|
<li>Has attachments (optional of specific type)</li>
|
|
|
<li>Header contains</li>
|
|
|
<li>Text contains (since version 1.1785)</li>
|
|
|
<li>Absolute time (received) between (since version 1.1540)</li>
|
|
|
<li>Relative time (received) between</li>
|
|
|
</ul>
|
|
|
<p>All the conditions of a rule need to be true for the rule action to
|
|
|
be executed. All conditions are optional, but there needs to be at least
|
|
|
one condition, to prevent matching all messages. If you want to match
|
|
|
all senders or all recipients, you can just use the @ character as
|
|
|
condition because all email addresses will contain this character. If
|
|
|
you want to match a domain name, you can use as a condition something
|
|
|
like <em><span class="citation"
|
|
|
data-cites="example.org">@example.org</span></em></p>
|
|
|
<p>Note that email addresses are formatted like this:</p>
|
|
|
<p><code>"Somebody" <somebody@example.org></code></p>
|
|
|
<p>When using a regex, you need to take care to match the complete
|
|
|
address.</p>
|
|
|
<p>Note that message texts are normalized when not using a regex, which
|
|
|
means that all whitespaces (spaces, tabs, line breaks, etc) are replaced
|
|
|
by a single space. This makes it easier to match texts on multiple lines
|
|
|
or when the line break is at different places.</p>
|
|
|
<p>Since version 1.1996 it is possible to use <a
|
|
|
href="https://jsoup.org/cookbook/extracting-data/selector-syntax">Jsoup
|
|
|
selectors</a> to match HTML elements, by prefixing the selector by
|
|
|
<em>jsoup:</em> and entering it as text contains condition, like for
|
|
|
example:</p>
|
|
|
<pre><code>jsoup:html > body > div > a[href=https://example.org]</code></pre>
|
|
|
<p>You can use multiple rules, possibly with a <em>stop processing</em>,
|
|
|
for an <em>or</em> or a <em>not</em> condition.</p>
|
|
|
<p>Matching is not case sensitive, unless you use <a
|
|
|
href="https://en.wikipedia.org/wiki/Regular_expression">regular
|
|
|
expressions</a>. Please see <a
|
|
|
href="https://developer.android.com/reference/java/util/regex/Pattern">here</a>
|
|
|
for the documentation of Java regular expressions. Note that you need to
|
|
|
match the complete text from the first to the last character. You can
|
|
|
test a regex <a href="https://regexr.com/">here</a>.</p>
|
|
|
<p>Note that a regular expression supports an <em>or</em> operator, so
|
|
|
if you want to match multiple senders, you can do this:</p>
|
|
|
<p><code>.*alice@example\.org.*|.*bob@example\.org.*|.*carol@example\.org.*</code></p>
|
|
|
<p>Note that <a
|
|
|
href="https://developer.android.com/reference/java/util/regex/Pattern#DOTALL">dot
|
|
|
all mode</a> is enabled to be able to match <a

|

|
|
|
<p>You can select one of these actions to apply to matching
|
|
|
messages:</p>
|
|
|
<ul>
|
|
|
<li>No action (useful for <em>not</em>)</li>
|
|
|
<li>Mark as read</li>

<li>Copy (Gmail: label)</li>
|

<li>Delete permanently (since version 1.1801)</li>

|
|

<li>Webhook (since version 1.2107)</li>
|

</ul>
|
|
|
<p><strong>Important</strong>: permanent deletion is
|
|
|
<strong>irreversible</strong>. Instead, consider to move messages to the
|
|
|
trash folder and to set up auto deletion for the trash folder in the
|
|
|
folder properties (long press the folder in the folder list of an
|
|
|
account).</p>
|
|
|
<p>If you want to forward a message, consider to use a <em>move</em>
|
|
|
action instead. This will be more reliable than forwarding because
|
|
|
forwarded messages might be considered as spam.</p>
|
|
|
<p><br></p>
|
|
|
<p>It is possible to use a <a
|
|
|
href="https://jsoup.org/cookbook/extracting-data/selector-syntax">Jsoup
|
|
|
selector</a> to select the text for notes, for example:</p>
|
|
|
<pre><code>jsoup:td > span:containsOwn(€)</code></pre>
|
|
|
<p>The text of the first matched HTML element up to 512 characters will
|
|
|
be used as text for the local note.</p>
|
|
|
<p><br></p>
|
|
|
<p>A <em>move</em> action can optionally create subfolders (since
|
|
|
version 1.1966) to move messages to, for which you can use the following
|
|
|
placeholders:</p>
|
|
|
<pre><code>$day$ (since version 1.2030)
|
|
|
$week$
|
|
|
$month$
|
|
|
$year$
|
|
|
$domain$
|
|
|
$group$ (since version 1.2030)</code></pre>
|
|
|
<p><span
|
|
|
class="math inline"><em>g</em><em>r</em><em>o</em><em>u</em><em>p</em></span>
|
|
|
will be replaced with the contact group name of the sender, provided
|
|
|
that the related contact is assigned to one contact group only. Note
|
|
|
that the Android contact provider isn’t very fast, so using this
|
|
|
placeholder can slow down fetching messages.</p>
|
|
|
<p><br /></p>
|
|
|
<p>Since version 1.2132 it is possible to use the following placeholders
|
|
|
in keywords:</p>
|
|
|
<pre><code>$day$
|
|
|
$week$

<p>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.</p>
|
|
|
<p>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.</p>

<p>The folder menu <em>Clear local messages</em> removes messages from

|
|
<p>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.</p>
|
|
|
<p>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 <em>the</em> next message
|
|
|
because in the meantime a new message might have been arrived.</p>
|
|
|
<p>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.</p>
|
|
|
<p>FairEmail is based on the state-of-the-art <a
|
|
|
href="https://developer.android.com/topic/libraries/architecture/">Android
|
|
|
architecture components</a>, so there is little room for performance

|
|
|
<p>In the receive settings you can enable scheduling and set a time
|
|
|
period and the days of the week <em>when</em> messages should be
|
|
|
<em>received</em>. Note that an end time equal to or earlier than the
|
|
|
start time is considered to be 24 hours later.</p>
|
|
|
<p>Since version 1.1880 is is possible to exclude accounts from
|
|
|
scheduling in the advanced account settings. This means you can
|
|
|
synchronize a business account during business hours only and make an
|
|
|
exception for personal accounts.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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.</p>
|
|
|
<p>It is also possible to create <a href="#faq71">rules</a> with a time
|
|
|
condition and to snooze messages until the end time of the time
|
|
|
condition. This way it is possible to <em>snooze</em> business related
|
|
|
messages until the start of the business hours. This also means that the
|
|
|
messages will be on your device for when there is (temporarily) no
|
|
|
internet connection. How to:</p>
|
|
|
<ul>
|
|
|
<li>Go to the folder list of an account by tapping on the account name
|
|
|
in the navigation menu (left side menu)</li>
|
|
|
<li>Long press the inbox in the folder list and select <em>Edit
|
|
|
rules</em></li>
|
|
|
<li>Tap om the big <em>plus</em> button at the bottom to create a new
|
|
|
rule</li>
|
|
|
<li>Enter as name for example <em>Snooze business messages</em></li>
|
|
|
<li>Under relative time select a start and end date/time, for example
|
|
|
Friday 17:00 and Monday 09:00</li>
|
|
|
<li>Select <em>Snooze</em> as action</li>
|
|
|
<li>Save the rule with the save button in the bottom action bar</li>
|
|
|
</ul>
|
|
|
<p>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 <a
|
|
|
href="https://support.google.com/android/answer/9069335">see here</a>
|
|
|
for more information.</p>
|
|
|
<p>Since version 1.2150 it is possible to create <a
|
|
|
href="#faq71">rules</a> to silence specific new message
|
|
|
notifications.</p>
|
|
|
<p>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:</p>
|
|
|
<pre><code>(adb shell) am start-foreground-service -a eu.faircode.email.POLL</code></pre>
|
|
|
<p>For a specific account:</p>
|
|
|
<pre><code>(adb shell) am start-foreground-service -a eu.faircode.email.POLL --es account Gmail</code></pre>
|
|
|
<p>You can also automate turning receiving messages on and off by
|
|
|
sending these commands to FairEmail:</p>
|
|
|
<pre><code>(adb shell) am start-foreground-service -a eu.faircode.email.ENABLE
|
|
|
(adb shell) am start-foreground-service -a eu.faircode.email.DISABLE</code></pre>
|
|
|
<p>To enable/disable a specific account:</p>
|
|
|
<pre><code>(adb shell) am start-foreground-service -a eu.faircode.email.ENABLE --es account Gmail
|
|
|
(adb shell) am start-foreground-service -a eu.faircode.email.DISABLE --es account Gmail</code></pre>
|
|
|
<p>Note that disabling an account will hide the account and all
|
|
|
associated folders and messages. Since version 1.1600 an account will be
|
|
|
disabled/enabled by setting the account to manual/automatic sync, so the
|
|
|
folders and messages keep being accessible.</p>
|
|
|
<p>To set the poll interval:</p>
|
|
|
<pre><code>(adb shell) adb shell am start-foreground-service -a eu.faircode.email.INTERVAL --ei minutes nnn</code></pre>
|
|
|
<p>Where <em>nnn</em> is one of 0, 5, 15, 30, 60, 120, 240, 480, 1440. A
|
|
|
value of 0 means push messages.</p>
|
|
|
<p>You can automatically send commands with for example <a
|
|
|
href="https://tasker.joaoapps.com/userguide/en/intents.html">Tasker</a>:</p>

<p>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.</p>
|
|
|
<p>You can also enable <em>Synchronize manually</em> in the advanced
|
|
|
account settings if you want to manually synchronize specific accounts
|
|
|
only.</p>
|
|
|
<p>You can use pull-down-to-refresh in a message list or use the folder

|
manually, just disable synchronization for the folders (but not of the

<p>By default FairEmail sends each message both as plain text and as

HTML formatted text because almost every receiver expects formatted

you can enable this in the send options. You can enable/disable sending

<p>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 <a
|
|
|
href="https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains">top
|

incorrectly recognized as links, which is better than not recognizing

some links.</p>

<p>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

<em>very</em> complex and adding more protocols will make it only slower

|
and possibly cause errors.</p>
|

<p>Note that original messages are shown exactly as they are, which

means also that links are not automatically added.</p>

|

|
|
|
href="https://en.wikipedia.org/wiki/Sender_Policy_Framework">SPF</a>
|
|
|
authorization is a task of email servers, not of an email client, which
|
|
|
is basically a viewer for messages on an email server. 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 for
|
|
|
one email client on one device. Moreover, email servers have access to
|
|
|
information, like the IP address, etc. of the connecting server, which
|
|
|
an email client has no access to. Furthermore, an email server can
|
|
|
inspect all messages of all email accounts, while an email client can
|
|
|
inspect messages in your email account only.</p>
|
|
|
<p>If you are receiving a significant amount of spam, the first thing
|
|
|
you should do is consider switching to another email provider. Some
|
|
|
email servers excell at filtering spam, and others are really bad at it.
|
|
|
Switching to another e-mail provider is no fun, but neither is wading
|
|
|
through piles of spam on a daily basis.</p>
|
|
|
<p>Spam filtering based on message headers might have been feasible, but
|
|
|
unfortunately this technique is <a
|
|
|
href="https://patents.google.com/patent/US7543076">patented by
|
|
|
Microsoft</a>.</p>
|
|
|
<p>Recent versions of FairEmail can filter spam to a certain extent
|
|
|
using a message classifier. Please see <a href="#faq163">this FAQ</a>
|
|
|
for more information about this.</p>
|
|
|
<p>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 <a href="#faq71">rules</a> too. Blocking the sender
|
|
|
will create a filter rule to automatically move future messages of the
|
|
|
same sender into the spam folder.</p>
|
|
|
<p>Note that the POP3 protocol gives access to the inbox only. So, it is
|
|
|
won’t be possible to report spam for POP3 accounts.</p>
|
|
|
<p>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.</p>
|
|
|
<p>If you are wondering why a message was moved into the spam folder,
|
|
|
these are all possible reasons:</p>
|
|
|
<ul>
|
|
|
<li>The email server of your email provider moved the message into the
|
|
|
spam folder. The app can’t undo this automatically because this can
|
|
|
result in an endless loop.</li>
|
|
|
<li>The message classifier (miscellaneous settings tab page) moved the
|
|
|
message into the spam folder.</li>
|
|
|
<li>A filter rule (navigation menu = left side menu of the start
|
|
|
screen), for example a block domain name rule, moved the message into
|
|
|
the spam folder.</li>
|
|
|
<li>An email address or a network address is on a block list (receive
|
|
|
settings tab page).</li>
|
|
|
</ul>
|
|
|
<p>Note that a sender will automatically be blocked when a message is
|
|
|
moved into the spam folder. You can disable this behavior by disabling
|
|
|
the option <em>Automatically block the sender when reporting spam</em>
|
|
|
in the behavior settings tab page.</p>
|
|
|
<p>Since version 1.2143, there is an “<em>Unblock all</em>” button in
|
|
|
the receive-settings tab page, which will reset all above options.</p>
|
|
|
<p>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.</p>
|
|
|
<p>Also, FairEmail can show a small red warning flag when DKIM, SPF or
|
|
|
<a href="https://en.wikipedia.org/wiki/DMARC">DMARC</a> authentication
|
|
|
failed on the receiving server. You can enable/disable <a
|
|
|
href="https://en.wikipedia.org/wiki/Email_authentication">authentication
|
|
|
verification</a> in the display settings. The feature depends on the
|
|
|
header <a
|
|
|
href="https://datatracker.ietf.org/doc/html/rfc7601">Authentication-Results</a>,
|
|
|
which the receiving email server should add. If the email server doesn’t
|
|
|
add an <em>Authentication-Results</em>, which is optional, you can
|
|
|
enable native DKIM in the debug panel, which appears when you enable
|
|
|
debug mode in the miscellaneous settings tab page (last option). Please
|
|
|
be aware that this option will increase both data and battery usage.</p>
|
|
|
<p>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.</p>
|
|
|
<p>If the domain name of the sender and the domain name of the reply
|
|
|
address differ, the warning flag will be shown too because this is most
|
|
|
often the case with phishing messages. If desired, this can be disabled
|
|
|
in the receive settings (since version 1.1506).</p>
|
|
|
<p>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 <a
|
|
|
href="https://www.mail-tester.com/">this tool</a> to check
|
|
|
authentication and other things.</p>

|

<p>Messages, attachments, etc stored on external storage media, like an

|
|
|
<p>Since version 1.1829 is it possible to store attachments to external

|
storage space private to the app (except for file managers) via an
|
|
|
option in the debug panel. You can enable the debug panel by enabling
|
|
|
debug mode in the miscellaneous settings (last option). To prevent
|
|
|
ongoing operations from storing attachments at the old location you
|
|
|
should disable receiving messages in the receive settings and wait until
|
|
|
all operations have been completed before changing this option. Please
|
|
|
be aware that removing the storage space will inevitably result in
|
|
|
problems, which is one of the reasons why this option is hidden.</p>
|
|
|
<p>Please note that more often than not the external storage space is
|
|
|
emulated on recent Android versions and recent devices. and that there
|
|
|
is no longer a viable way to get permission to write to other

locations.</p>
|
|

<p>Moving messages to an sdcard is not an option because this would

<p>If you need to save on storage space, you can limit the number of

<p>Please <a

here</a> for a list of launchers which can show the number of unread
|
|
|
messages. Standard Android <a
|
|
|
href="https://developer.android.com/training/notify-user/badges">does
|
|
|
not support this</a>.</p>
|
|
|
<p>Note that Nova Launcher requires Tesla Unread, which is <a
|
|
|
href="https://forum.xda-developers.com/android/general/bad-news-tesla-unread-devoloper-t3920415">not
|
|
|
supported anymore</a>.</p>
|
|
|
<p>Note that the notification setting <em>Show launcher icon with number
|
|
|
of new messages</em> needs to be enabled (default enabled).</p>
|
|
|
<p>Only <em>new</em> 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.</p>
|
|
|
<p>Depending on what you want, the notification settings <em>Let the
|
|
|
number of new messages match the number of notifications</em> needs to
|
|
|
be enabled (default disabled). When enabled the badge count will be the
|
|
|
same as the number of new message notifications. When disabled the badge
|
|
|
count will be the number of unread messages, independent if they are
|
|
|
shown in a notification or are new.</p>
|
|
|
<p>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.</p>
|
|
|
<p>An alternative is to use the unread messages count home screen
|
|
|
widget. You can add this widget by long pressing on an empty place on
|
|
|
the home screen.</p>
|
|
|
<p>If you are using Nova launcher and you want to show the number of
|
|
|
notifications in the launcher icon (maximum 10; imposed by Nova
|
|
|
launcher), you’ll need to enable <em>Notification access</em> in the
|
|
|
Android <em>Special app access</em> settings for Nova launcher on recent
|
|
|
Android versions.</p>
|
|
|
<p>Some launchers display a dot or a ‘1’ for <a href="#faq2">the
|
|
|
monitoring notification</a>, despite FairEmail explicitly requesting not
|
|
|
to show a <em>badge</em> for this notification. This could be caused by
|
|
|
a bug in the launcher app or in your Android version. Please double
|
|
|
check if the notification dot (badge) is disabled for the receive
|
|
|
(service) notification channel. You can go to the right notification
|
|
|
channel settings via the notification settings of FairEmail. This might
|
|
|
not be obvious, but you can tap on the channel name for more
|
|
|
settings.</p>
|
|
|
<p>FairEmail does send a new message count <em>broadcast</em> intent as

|
well:</p>
|

|
<p>You need to know that colored stars are not supported by the IMAP

means that colored stars will not be visible in other email clients and

<p>Some email clients use IMAP keywords for colors. However, not all

<p>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

|
|
<p>Settings > Manual setup > Accounts > tap account > tap

|
|
advanced > Partial fetch > uncheck</p>
|
|
|
<p>After disabling this setting, you can use the message ‘more’ (three

|
|
|
<p>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.</p>
|
|
|
<p>Biometric authentication is meant to prevent others from seeing your
|
|
|
messages only. FairEmail relies on device encryption for data
|
|
|
encryption, see also <a href="#faq37">this FAQ</a>.</p>

<p>The format of the settings files of most other email apps is not

|
documented, so this is difficult. Sometimes it is possible to reverse

|
|
engineer the format, but as soon as the settings format changes things
|
|
|
will break. Also, settings are often incompatible. For example,
|
|
|
FairEmail has unlike most other email apps settings for the number of

|
|
days to synchronize messages and for the number of days to keep
|
|
|
messages, mainly to save on battery usage. Moreover, setting up an

|
|
|
<p>Firstly, a purchase will be available on all devices logged into the
|
|
|
same Google account, <em>if</em> (this is important) the app is
|
|
|
installed via the same Google account too. You can select the account in
|
|
|
the Play store app by tapping on the avatar at the top right, but only
|
|
|
<em>before</em> installing the app. It is not possible to change the
|
|
|
linked Google account after the app has been installed.</p>
|
|
|
<p>Google manages all purchases, so as a developer I have little control
|
|
|
over purchases. So, basically, the only thing I can do, is suggest some
|
|
|
things:</p>
|
|
|
<ul>
|
|
|
<li>Make sure you have an active, working internet connection, and turn
|
|
|
off any VPN based app because it might prevent the Play store from
|
|
|
checking purchases</li>
|
|
|
<li>Make sure you are logged in with the right Google account and that
|
|
|
there is nothing wrong with your Google account</li>
|
|
|
<li>Make sure you installed FairEmail via the right Google account if
|
|
|
you configured multiple Google accounts on your device (you might need
|
|
|
to reinstall the app)</li>
|
|
|
<li>Make sure the Play store app is up to date, please <a
|
|
|
href="https://support.google.com/googleplay/answer/1050566?hl=en">see
|
|
|
here</a></li>
|
|
|
<li>Open the Play store app and wait at least a minute to give it time
|
|
|
to synchronize with the Google servers</li>
|
|
|
<li>Open FairEmail and navigate to the pro features screen to let
|
|
|
FairEmail check the purchases; sometimes it helps to tap the
|
|
|
<em>buy</em> button</li>
|
|
|
</ul>
|
|
|
<p>You can also try to clear the cache of the Play store app via the
|
|
|
Android apps settings. Restarting the device might be necessary to let
|
|
|
the Play store recognize the purchase correctly.</p>
|
|
|
<p>Note that:</p>
|
|
|
<ul>
|
|
|
<li>If you get <em>ITEM_ALREADY_OWNED</em>, the Play store app probably
|
|
|
needs to be updated, please <a
|
|
|
href="https://support.google.com/googleplay/answer/1050566?hl=en">see
|
|
|
here</a></li>
|
|
|
<li>If you get <em>BILLING_UNAVAILABLE Google Play In-app Billing API
|
|
|
version is less than 3</em>, the Play store app might not be logged into
|
|
|
the account used to install the app</li>
|
|
|
<li>Purchases are stored in the Google cloud and cannot get lost</li>
|
|
|
<li>There is no time limit on purchases, so they cannot expire</li>
|
|
|
<li>Google does not expose details (name, e-mail, etc) about buyers to
|
|
|
developers</li>
|
|
|
<li>An app like FairEmail cannot select which Google account to use</li>
|
|
|
<li>It may take a while until the Play store app has synchronized a
|
|
|
purchase to another device</li>
|
|
|
<li>Play Store purchases cannot be used without the Play Store
|
|
|
app/services</li>
|
|
|
<li>Play Store purchases cannot be transferred to another account</li>
|
|
|
<li>You can’t restore purchases with <a

<p>New message notifications will be removed on swiping notifications

<p>By default FairEmail groups messages in conversations. This can be

turned of in the display settings.</p>
|
|

<p>FairEmail groups messages based on the standard <em>Message-ID</em>,

|
|
<em>In-Reply-To</em> and <em>References</em> headers. FairEmail does not
|
|
|
group on other criteria, like the subject, because this could result in

|
<p>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 or aborting the connection, FairEmail will retry
|
|
|
one time after waiting 8 seconds while keeping the device awake (=use
|
|
|
battery power). If this fails, FairEmail will schedule an alarm to retry
|
|
|
after 5, 15, 30 and eventually every 60 minutes and let the device sleep
|
|
|
(=no battery usage).</p>
|
|
|
<p>By temporarily enabling debug mode in the miscellaneous settings, you
|
|
|
can disable this logarithmic back-off scheme (since version 1.1855).
|
|
|
This will result in using a linear back-off scheme, which means that
|
|
|
after each successive failure the waiting time will be increased by 1
|
|
|
minute the first 5 minutes and thereafter by 5 minutes up to 60 minutes.
|
|
|
This might increase the battery usage significantly!</p>

|
<p>Note that <a
|
|
|

|
|
|
doze mode</a> does not allow to wake the device earlier than after 15
|
|
|
minutes when doze mode is active.</p>
|
|
|
<p><em>Force sync</em> in the three-dots menu of the unified inbox can
|
|
|
be used to let FairEmail attempt to reconnect without waiting.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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.</p>

<p>In the account settings (Settings, tap Manual setup, tap Accounts,

|
<em>Leave deleted messages on server</em>.</p>
|
|
|
<p><em>IMAP</em></p>
|
|
|
<p>Since the IMAP protocol is meant to synchronize two ways, from server
|
|
|
to client and from client to server, trashing (=move to trash) and
|
|
|
(permanently) deleting messages will be performed on the email server
|
|
|
too, so that the message list is the same for all connected clients.
|
|
|
Deleting a message from the device only won’t work because it would be
|
|

synchronized again later.</p>
|
|
|
<p>Some email apps pretend they can do this, but, in fact, messages are

|
hidden on the device. FairEmail can do this too, but in a more explicit

way, also allowing you to show the messages again.</p>
|
|
|
<p>You can hide messages either via the three-dots menu in the action
|
|

bar just above the message text (you can configure a button for this via
|
|
|
the same menu) or by multiple selecting messages in the message

<p>Alternatively, you can disable AUTO EXPUNGE, which will result in

marking messages being deleted on the server (by setting the

<em>deleted</em> flag), but not expunging (deleting) them. You can find

|
|
this option in the debug panel, which can be shown by (temporarily)
|

enabling debug mode in the miscellaneous settings.</p>

<p>Note that it is possible to set the swipe left or right action to

<p>Individual messages will rarely be trashed and mostly this happens by

|

<p>Displaying strange characters is almost always caused by specifying

will assume <a href="https://en.wikipedia.org/wiki/ISO/IEC_8859-1">ISO

|
|
<p>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.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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 <em>Show in unified inbox</em>. This way all messages can stay
|
|
|
where they belong, while allowing to see both incoming and outgoing
|
|
|
messages at one place.</p>
|
|
|
<p>If this is not an option, you can <a href="#faq71">create a rule</a>
|
|
|
to automatically move sent messages to the inbox or set a default CC or
|
|
|
BCC address in the advanced identity settings (via the manual setup in
|
|
|
the main setup screen) to send yourself a copy.</p>

<p><a href="https://en.wikipedia.org/wiki/Post_Office_Protocol">POP3</a>
|

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.</p>
|
|
|
<p>Since POP3 does not allow access to the trash folder at all, there is
|
|
|
no way to restore trashed messages.</p>
|
|
|
<p>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.</p>
|
|
|
<p>Version 1.1082 added a local trash folder. Note that trashing a

|
|
|
<p>Since the sent date/time is optional and can be manipulated by the
|
|
|
sender, FairEmail uses the server received date/time by default.</p>
|
|
|
<p>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.</p>
|
|
|
<p>In these rare cases, it is possible to let FairEmail use either the
|
|
|
date/time from the <em>Date</em> header (sent time) or from the
|
|
|
<em>Received</em> header as a workaround. This can be changed in the
|
|
|
advanced account settings: go to the Settings, tap <em>Manual setup and

|
|
|
<p>You likely came here because you are using a third party build of
|
|
|
FairEmail.</p>
|
|
|
<p>There is <strong>only support</strong> on the latest Play store
|
|
|
version, the latest GitHub release and the F-Droid build, but
|
|
|
<strong>only if</strong> the version number of the F-Droid build is the
|
|
|
same as the version number of the latest GitHub release.</p>
|
|
|
<p>F-Droid builds irregularly, which can be problematic when there is an
|
|
|
important update. Therefore you are advised to switch to the GitHub
|
|
|
release.</p>
|
|
|
<p>Note that developers have no control over F-Droid builds and the
|
|
|
F-Droid infrastructure (apps, forums, etc.).</p>
|
|
|
<p>OAuth access is available only for Play Store and Github releases
|
|
|
because email providers permitted the use of OAuth for these releases
|
|
|
only. The responsible for a release, for the F-Droid build this is the
|
|
|
F-Droid organization, needs to ask for OAuth permissions, which mostly
|
|
|
involves signing a contract with binding terms and conditions.</p>
|
|
|
<p>Note that you’ll need to uninstall the F-Droid build first before you
|
|
|
can install a GitHub release because Android refuses to install
|
|
|
(“<em>App was not installed</em>”) the same app with a different
|
|
|
signature for security reasons.</p>
|
|
|
<p>At the start of 2024, the Play Store app started to update all apps,
|
|
|
including apps not installed via the Play Store. Since the F-Droid build
|
|
|
is signed by the F-Droid organization, which basically means the F-Droid
|
|
|
build is another app, updating the F-Droid build will fail.
|
|
|
Unfortunately, there is no way to resolve this.</p>
|
|
|
<p>Note that the GitHub version will automatically check for updates.
|
|
|
When desired, this can be turned off in the miscellaneous settings.</p>

|

is a newer GitHub version first.</p>

|
<p>Permanent deletion means that messages will <em>irreversibly</em> 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 :-(</p>

|
|
|
<p>Since version 1.1601 it is possible to disable confirmation of
|
|
|
permanent deletion of individual messages after reading a big
|
|
|
warning.</p>
|
|
|
<p>Note that the POP3 protocol can download messages from the inbox

|
only. So, deleted messages cannot be uploaded to the inbox again. This
|
|
|
means that messages can only be permanently deleted in case of a POP3
|
|
|
account.</p>
|
|
|
<p>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 <a

<p>Since version 1.1485 it is possible to temporarily enable debug mode

<p>Yes, <a href="https://tools.ietf.org/html/rfc5465">IMAP NOTIFY</a>

|
|
|
<p>IMAP NOTIFY support means that notifications for added, changed or

and if a notification is received for a subscribed folder, that the

<p><em>This is an experimental feature!</em></p>
|
|
|
<p>Message classification will attempt to automatically group emails
|
|
|
into classes, based on their contents, using <a
|
|
|
href="https://en.wikipedia.org/wiki/Bayesian_statistics">Bayesian
|
|
|
statistics</a>. In the context of FairEmail, a folder is a class. So,
|
|
|
for example, the inbox, the spam folder, a ‘marketing’ folder, etc,
|
|
|
etc.</p>
|
|
|
<p>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 <em>Classify new messages in this folder</em> 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.</p>
|
|
|
<p>Each folder has an option <em>Automatically move classified messages
|
|
|
to this folder</em> (‘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.</p>
|
|
|
<p>The option <em>Use local spam filter</em> 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 <a
|
|
|
href="https://en.wikipedia.org/wiki/False_positives_and_false_negatives">false
|
|
|
positives and false negatives</a>. See also <a href="#faq92">this
|
|
|
FAQ</a>.</p>
|
|
|
<p>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).</p>
|
|
|
<p>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.</p>
|
|
|
<p>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.</p>
|
|
|
<p>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:</p>
|
|
|
<ul>
|
|
|
<li><em>Minimum class probability</em>: a message will only be moved
|
|
|
when the confidence it belongs in a folder is greater than this value
|
|
|
(default 15 %)</li>
|
|
|
<li><em>Minimum class difference</em>: 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 %)</li>
|
|
|
</ul>
|
|
|
<p>If all previously classified messages were the same and the message
|
|
|
being evaluated is also the same, the confidence would be 100%.</p>
|
|
|
<p>Both conditions must be satisfied before a message will be moved.</p>
|
|
|
<p>Considering the default option values:</p>
|
|
|
<ul>
|
|
|
<li>Apples 40 % and bananas 30 % would be disregarded because the
|
|
|
difference of 25 % is below the minimum of 50 %</li>
|
|
|
<li>Apples 10 % and bananas 5 % would be disregarded because the
|
|
|
probability for apples is below the minimum of 15 %</li>
|
|
|
<li>Apples 50 % and bananas 20 % would result in selecting apples</li>
|
|
|
</ul>
|
|
|
<p>Classification is optimized to use as little resources as possible,
|
|
|
but will inevitably use some extra battery power. This is also why only
|
|
|
folders of the same account will be considered.</p>
|
|
|
<p>You can delete all classification data by turning classification in
|
|
|
the miscellaneous settings three times off. This will be necessary when
|
|
|
classification for a folder is enabled or disabled (or when a folder is
|
|
|
deleted) because classification is based on comparision.</p>
|
|
|
<p><a href="#faq71">Rules</a> will be executed before classification. If
|
|
|
one or more rules were executed for a message, message classification
|
|
|
will be skipped because it is assumed that the message will be processed
|
|
|
by the rules in this case.</p>
|
|
|
<p>Message classification is a pro feature, except for the spam

folder.</p>

|
|
|
<p>First of all, there is no standard for snoozing messages, so all
|
|
|
snooze implementations are custom solutions.</p>
|
|
|
<p>Some email providers, like Gmail, move snoozed messages to a special
|
|
|
folder. Unfortunately, third party apps have no access to this special
|
|
|
folder.</p>
|
|
|
<p>Moving a message to another folder and back might fail and might not
|
|
|
be possible if there is no internet connection. This is problematic
|
|
|
because a message can be snoozed only after moving the message.</p>
|
|
|
<p>To prevent these issues, snoozing is done locally on the device by
|
|
|
hiding the message while it is snoozing. Unfortunately, it is not
|
|
|
possible to hide messages on the email server too. Deleting messages
|
|
|
from the server and restoring them later could result in losing messages
|
|
|
when the device breaks.</p>

<p>A spam block list is basically a list of domain names which have been

|
used to send spam or to spread malware.</p>
|
|
|
<p>A spam block list is checked by resolving the server name from the
|
|
|
last <em>Received</em> header into an IP address and looking up the IP
|
|
|
address with a DNS request:</p>
|
|
|
<pre><code>Received:

<p>FairEmail requests Android to start the app when the device starts

up. Obviously, this depends on Android as the app cannot start
|
|
|
itself.</p>
|
|
|
<p>Some Android versions, such as EMUI, have settings to enable or
|
|
|
disable auto starting apps. So, if the app isn’t started automatically,

please check the Android settings.</p>

<p>The POP3 protocol has commands to download and delete messages from

|
the inbox only. There are no commands to access any other folder.</p>
|
|
|
<p>Creating a local folder only and storing messages on your device only
|
|
|
is a bad idea because losing or breaking your device would mean losing
|
|
|
your messages. Therefore this isn’t supportable.</p>
|
|
|
<p>Please note that FairEmail doesn’t store a copy of your messages in
|
|
|
the cloud for privacy reasons.</p>
|
|
|
<p>If you want to store messages in folders, please use IMAP, so that
|
|
|
there is always a copy of the messages on the email server.</p>
|
|
|
<p>You could register, for example, a Gmail account, and configure Gmail

to import messages from a POP3 account, automatically label them (=put

|
|
|
<p>Like most Android apps, FairEmail consults the Android address book
|
|
|
for contact information.</p>
|
|
|
<p>There is also a local contact database, which is filled with contacts
|
|
|
from sent and received messages. You can enable/disable this in the send
|
|
|
settings of the app.</p>
|
|
|
<p>If you want to import contacts into the local contact database, this
|
|
|
is possible (in recent versions of the app) by tapping on the
|
|
|
<em>Manage</em> button in the send settings. In the three-dots menu at
|
|
|
the top right there is an import (and also an export) <a
|
|
|
href="https://en.wikipedia.org/wiki/VCard">vCard</a>s menu item.</p>
|
|
|
<p>The Android address book is managed by the Android Contacts app (or a
|
|
|
replacement for this app). Please see <a
|
|
|
href="https://support.google.com/contacts/answer/1069522">this
|
|
|
article</a> about importing contacts to the Android address book.</p>
|
|
|
<p>Note that some vendors, notably Microsoft, try to lock you into their
|
|
|
contact (data) storage. This is not how it should work on Android, which
|
|
|
is more open to sharing information.</p>

update the F-Droid build with the Play store or GitHub version or the

|
other way around without reinstalling. However, it is possible to

install the GitHub version over the Play store version, and the Play

|

<p>The GitHub version will automatically check for updates and notify

<p>Apps provide the layout and data for widgets on demand, but the
|
|
|
homescreen app/launcher manages all widgets, with a little help from
|
|
|
Android.</p>
|
|
|
<p>If widgets are not being updated, this is often caused by missing
|
|
|
permission. Please see <a

|
|
<p>Reply templates are predefined answer texts. They can be defined via
|
|
|
the main navigation menu (left side menu).</p>
|
|
|
<p>You can reply with a template, insert a template via the three-dots
|
|
|
overflow menu in the message editor, and long press on an open space to
|
|
|
insert a snippet (the latter requires Android 6 Marshmallow or
|
|
|
later).</p>
|
|
|
<p>Templates can have the following options:</p>
|
|
|
<ul>
|
|
|
<li><em>Default</em>: standard template to use when writing a new
|
|
|
message</li>
|
|
|
<li><em>Use as read receipt</em>: template to use instead of the default
|
|
|
read receipt text</li>
|
|
|
<li><em>Favorite</em>: template will be added in the main reply popup
|
|
|
menu</li>
|
|
|
<li><em>Snippet</em>: template will be used as text fragment (since
|
|
|
version 1.1857)</li>
|
|
|
<li><em>Hide from menus</em>: template will be hidden (disabled)</li>
|
|
|
</ul>
|
|
|
<p>Since version 1.2068 it is possible to send a template message with
|
|
|
an intent:</p>
|
|
|
<pre><code>(adb shell) am start-foreground-service -a eu.faircode.email.TEMPLATE --es template <template name> --es identity <identity display name> --es to <email address> --es cc <email address> --es subject <subject></code></pre>
|
|
|
<p><strong>Important</strong>: you need to configure a display name for
|
|
|
the identity, and use this to identify the identity.</p>

shown. The available browser(s) will be listed and if a browser supports
|
|

once without this icon (the browser will be started embedded as “Custom

<p>Password protected content is a simple, yet secure form of end-to-end
|
|
|
encryption that requires no configuration.</p>
|
|
|
<p>How to use: select some text by long pressing it, and in the style
|
|
|
toolbar at the bottom tap on the <em><ins>A</ins></em>-button and select
|
|
|
<em>Password protect</em> in the pop-up menu. This will replace the
|
|
|
selected content with a link that the recipient can click to decrypt the
|
|
|
content on a dedicated static web page.</p>
|
|
|
<p>Password protected content is sent as a <a
|
|
|
href="https://en.wikipedia.org/wiki/URI_fragment">URI fragment</a> and
|
|
|
decrypted in the browser with JavaScript. In other words, protected
|
|
|
content is never stored on or seen by third party servers. Since version
|
|
|
1.1990 received protected content will be decrypted by the app, with as
|
|
|
fallback decryption in the browser for other email clients.</p>
|
|
|
<p>Password protected content is encrypted with <a
|
|
|
href="https://en.wikipedia.org/wiki/Advanced_Encryption_Standard">AES</a>
|
|
|
/ <a href="https://en.wikipedia.org/wiki/Galois/Counter_Mode">GCM</a>

|
|
|
href="https://en.wikipedia.org/wiki/Secure_Hash_Algorithms">SHA</a>-512

with 120,000 iterations. With a sufficiently long/complex password,

|
<p>Cloud sync is meant to synchronize configuration data across devices.
|
|
|
It can be used to restore configuration data onto a new device too.</p>
|
|
|
<p>Cloud sync is based on a cloud account. You can register/login by
|
|
|
entering a username and a password and using the <em>Login</em>
|
|
|
button.</p>
|
|
|
<p>A cloud sync account needs to be activated, which is to prevent
|
|
|
misusing the cloud sync server. To activate a cloud sync account, use
|
|
|
the <em>Activate</em> button to send an email to a special email
|
|
|
address. The email needs to come from an address used to activate the
|
|
|
pro features before. You’ll receive an email in response indicating
|
|
|
whether the activation was succesful or not.</p>
|
|
|
<p>The app will automatically synchronize once a day around 1:30 AM,
|
|
|
provided there is an internet connection, otherwise synchronization will
|
|
|
be postponed until after an internet connection becomes available. You
|
|
|
can also manually synchronize with the opposite arrows button.</p>
|
|
|
<p>Synchronization will currently add and update enabled accounts and
|
|
|
identities only, but on the roadmap is synchronizing blocked senders and
|
|
|
rules too.</p>
|
|
|
<p>Updating includes enabling/disabling accounts and identities.</p>
|
|
|
<p>Existing accounts or identities will never be deleted</p>
|

<p>OpenAI can only be used if configured and enabled.</p>
|
|
|
<p><strong>Setup</strong></p>
|
|
|
<ul>
|
|
|
<li>Create an account <a

<p><br></p>
|
|
|
<p><strong>Usage</strong></p>
|
|
|
<p>Tap on the robot button in the top action bar of the message editor.
|
|
|
The text in the message editor (if any) and the first part of the
|
|
|
message being replied to (if any) will be used for <a
|
|
|
href="https://platform.openai.com/docs/guides/chat/introduction">chat

|
|
selected text will be used, and it will be replaced by the answer. A
|
|
|
maximum of 1,000 characters of the message being replied to will be used
|
|
|
to avoid exceeding the token limit.</p>
|
|
|
<p>For example: create a new draft and enter the text “<em>How far is
|
|
|
the sun?</em>”, and tap on the robot button in the top action bar.</p>
|
|
|
<p><br></p>
|
|
|
<p>OpenAI isn’t very fast, so be patient. Sometimes a timeout error
|
|
|
occurs because the app is not receiving a response from OpenAI.</p>
|
|
|
<p><br></p>
|
|
|
<p>Depending on the ChatGPT account (free or paid) there are usage

<p>If there are one or more Outlook or Office 365 accounts configured,

there will be a button in the main settings screen in setup step 2 to

|
|
download Outlook contacts (since version 1.2076). After tapping on this
|
|
|
button, you can select the account to download contacts for. Microsoft
|
|

will ask for permission to read the contacts, and after granting this
|
|
|
permission, the app will download the contacts with an email address

into the local contacts’ database.</p>

<p>For privacy and security reasons, FairEmail doesn’t have permissions

<ul>

|

<p>Unread, starred and snoozed messages and messages younger than 24

|
|
unread messages in the receive-settings tab page (option <em>Delete old
|
|
|

|
|
|
<p>Note that it isn’t a good idea to automatically delete recent
|
|
|
messages, especially not for the spam folder because there might be
|
|
|
legitimate messages in the spam folder. There is a button or menu item
|
|
|
(depending on the screen size) in the top action bar/menu of the trash

|
and spam folder to empty the folder. This way there is at least a visual

|
|
check.</p>
|
|
|
<p>Auto deletion will be done on a full sync only. For the inboxes, you
|
|
|
can use <em>Force sync</em> in the three-dots overflow menu of the start

<p>The Gmail server stores all messages, except the messages in the
|
|
|
draft, sent, trash and spam messages folder in the all messages’ folder
|
|
|
(=archive folder). FairEmail is an email client, which basically
|
|
|
displays what is on the email server, and therefore it will show these
|
|
|
messages too.</p>
|
|
|
<p>To be clear: FairEmail does not store the messages in the archive
|
|
|
folder, unless you explicitly archive a message.</p>
|
|
|
<p>This has advantages, though, because it makes searching in all
|
|

messages easier.</p>

|
|
|
<p>Besides that leaving an app is an ambiguous action, automatically
|
|
|
deleting trashed messages is a risky action because deleted messages
|
|
|
can’t be restored anymore. A message could accidentally be trashed, and
|
|
|
you could switch to another app, which could be interpreted as leaving
|
|
|
the app, and the message would be gone forever.</p>
|
|
|
<p>Instead, you can configure auto-deletion of older messages, which is
|
|
|
safer because the messages won’t be deleted immediately. For this,
|
|
|
please tap on the account name in the navigation menu (left side menu)
|

to go to the folder list of the account. In the folder list, long press

the end of the properties screen, there is a checkbox to enable

auto-deletion. You might want to change the number of days to keep

messages on your device.</p>

<p>In fact, (HTTP, HTTPS, SOCKS) proxy support was removed because it is

not possible to let an app proxy DNS requests, or in other words, an

|
|
|
limited number of DNS servers support DNSSEC (January 2024: ~30%), which
|
|
|
is required for DANE. Most private DNS providers support DNSSEC, though.
|
|
|
You can configure private DNS in the Android network settings (since
|
|
|
Android 9). To be sure that private DNS is being used, better configure
|
|
|
a host name like <em>dns.google</em>,
|
|
|
<em>1dot1dot1dot1.cloudflare-dns.com</em> or <em>dns.quad9.net</em>. An
|
|
|
alternative is using Certificate Transparency, see the previous FAQ.</p>
|
|
|
<p>Some email providers known to support DANE for client-to-server
|
|
|
traffic:</p>

<p>FairEmail is supported on Android smartphones and tablets and
|
|
|
ChromeOS only.</p>
|
|
|
<p>There is support only if the app was downloaded via one of the <a
|
|
|
href="https://github.com/M66B/FairEmail#downloads">supported download
|
|
|
locations</a>.</p>
|
|
|
<p>Only the latest Play store version and latest GitHub release are
|
|
|
supported. The F-Droid build is supported only if the version number is
|
|
|
the same as the version number of the latest GitHub release. This also
|
|
|
means that downgrading is not supported.</p>
|
|
|
<p>There is no support for things that are not directly related to
|
|
|
FairEmail.</p>
|
|
|
<p>There is no support on building and developing things by
|
|
|
yourself.</p>

|
<p><a name="feature_request"></a></p>
|
|
|
<p>A change will be considered only if more than a few people ask for
|
|
|
it. Changes in the past resulted too often in lots of complaints of
|
|
|
other people.</p>
|
|
|
<p>Requested features should:</p>
|
|
|
<ul>
|
|
|
<li>within the scope of the app</li>
|
|
|
<li>be useful to more than a few people</li>
|
|
|
<li>fit logically and consistently within the app</li>
|
|
|
<li>fit within the philosophy of the app (privacy-oriented,
|
|
|
security-minded)</li>
|
|
|
<li>comply with common standards (IMAP, SMTP, etc.)</li>
|
|
|
<li>comply with the <a
|
|
|
href="https://developer.android.com/docs/quality-guidelines/core-app-quality">Core
|
|
|
app quality guidelines</a></li>
|
|
|
</ul>
|
|
|
<p>Features unrelated to email, including reading newsgroups and reading
|
|
|
RSS feeds, fall outside the scope of the project.</p>
|
|
|
<p>The goal of the design is to be minimalistic (no unnecessary menus,
|
|
|
buttons, etc) and non distracting (no fancy colors, animations, etc).
|
|
|
All displayed things should be useful in one or another way and should
|
|
|
be carefully positioned for easy usage. Fonts, sizes, colors, etc should
|
|
|
be material design whenever possible.</p>
|
|
|
<p>There are requests daily to change the appearance in this or that
|
|
|
way, but the problem is that these requests are more often than not
|
|
|
conflicting. To prevent making other people unhappy, changes in the
|
|
|
appearance always need to clearly and objectively contribute to the
|
|
|
usability of the app to be considered.</p>
|
|
|
<p>A feature will be considered useful to most people if more than 0.1%
|
|
|
of the users request a feature, which in practice means about 500
|
|
|
people.</p>
|
|
|
<p>Features not fulfilling these requirements will likely be rejected.
|
|
|
This is also to keep maintenance and support in the long term feasible.
