Right now there big differences, after the forked, the two apps have an independent development and different paths and the focus of SimpleEmail is be a simple, privacy-friendly app with a good UX/UI and minimalistic design.
please see the CHANGELOG for more detail about the changes.
A permanent status bar notification with the number of accounts being synchronized and the number of operations pending is shown to prevent Android from killing the service that takes care of receiving and sending email.
Most, if not all, other email apps don't show a notification with the "side effect" that new email is often not or late being reported.
Background: this is because of the introduction of doze mode in Android 6 Marshmallow.
The low priority status bar notification shows the number of pending operations, which can be:
Operations are processed only when there is a connection to the email server or when manually synchronizing. See also this FAQ.
Valid security certificates are officially signed (not self signed) and have matching a host name.
Without IMAP IDLE emails need to be periodically fetched.
Since January 2020 Gmail restricted the oAuth scopes, now requires authorization to be able to authenticate, we are looking the best way to fix oAuth authentication without privative libraries.
As a temporary solution you need to allow normal authentication (non-oAuth) or how Google says "less secure apps". See here for instructions: https://support.google.com/accounts/answer/6010255
Messages in the outbox are moved to the sent folder as soon as your provider adds the message to the sent folder. If this doesn't happen, your provider might not keep track of sent messages or you might be using an SMTP server not related to the provider. In these cases you can enable the account option Store sent messages to let the app move messages from the outbox to the sent folder after sending. There is a menu to move sent messages to the sent folder after enabling this option.
You can use a Microsoft Exchange account if it is accessible via IMAP. ActiveSync is not supported at this moment. See here for more information: https://support.office.com/en-us/article/what-is-a-microsoft-exchange-account-47f000aa-c2bf-48ac-9bc2-83e5c6036793
Identities represent email addresses you are sending from.
Some providers allow you to have multiple email aliases. You can configure these by setting the email address field to the alias address and setting the user name field to your main email address.
The error message UIDPLUS not supported means that your email provider does not provide the IMAP UIDPLUS extension. This IMAP extension is required to implement two way synchronization, which is not an optional feature. So, unless your provider can enable this extension, you cannot use SimpleEmail for this provider.
STARTTLS starts with a not encrypted connection and is therefore not secure.
All well known IMAP servers support IMAP with a plain SSL connection, so there is no need to support STARTTLS for IMAP.
If you encounter an IMAP server that requires STARTTLS, please let me know.
For more background information, please see this article.
tl;dr; "Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted."
First of all you need to install and configure OpenKeychain. To encrypt a message before sending, just select the menu Encrypt. Similarly, to decrypt a received message, just select the menu Decrypt.
You can start searching for messages on sender, recipient, subject or message text by using the magnify glass in the action bar of a folder (not in the unified inbox because it could be a collection of folders). The server executes the search. Scrolling down will fetch more messages from the server. Searching by the server might be case sensitive or case insensitive and might be on partial text or whole words, depending on the provider. Search on server is a pro feature.
To use Outlook with two factor authentication enabled, you need to create an app password. See here for the details.
Possible causes of messages not being synchronized (sent or received) are:
So, check your account and folder settings and check if the accounts/folders are connected (see the legend menu for the meaning of the icons).
On some devices, where there are lots of applications competing for memory, Android may stop the synchronization service as a last resort. Some Android versions, in particular of Huawei (see here for a fix) or Xiaomi (see here for a fix) stop apps and services too aggressively.
If the Synchronize now menu is dimmed, there is no connection to the account.
See the previous question for more information.
Before Android 8 Oreo: there is an advanced option in the setup for this.
Android 8 Oreo and later: see here about how to configure notification channels.
The message Couldn't connect to host ... means that SimpleEmail was not able to connect to the email server.
Possible causes are:
If you are using a VPN, the VPN provider might block the connection because it is too aggressively trying to prevent spam.
The message Too many simultaneous connections is sent by the email server when there are too many connections to the same email account at the same time.
Possible causes are:
Browse messages on the server will fetch messages from the email server in real time when you reach the end of the list of synchronized messages, even when the folder is set to not synchronize. You can disable this feature under Setup > Advanced options > Browse messages on the server.
If a menu item to select a file is disabled (dimmed), likely the storage access framework, a standard Android component, is not present, for example because your custom ROM does not include it or because it was removed. SimpleEmail does not request storage permissions, so this framework is required to select files and folders. No app, except maybe file managers, targetting Android 4.4 KitKat or later should ask for storage permissions because it would allow access to all files.
Yes, you can translate the texts of SimpleEmail in your own language, please open a pull requests with the changes, we are looking for web service to automated the process.
If you have another question, want to request a feature or report a bug, please open a issue, send a email or open PR.
