I’m looking for an email client (IMAP) for Android, which supports
- multiple accounts, and
- multiple From addresses per account (aka. identities, aliases).
When composing a new email, it must be possible to choose a From address. It would be great if there is no default, so the user has to make a choice.
When answering an email, the client should automatically choose the From address the original email was sent to. But it should also be possible to change the From address manually.
Gratis is required, FLOSS would be great.
