You have to use full usernames like:
user1@mydomain.org user2@mydomain.org user3@mydomain.org
user1 != user1@mydomain.org
I understand that technical issue, but what I wanted was a possible solution based on plain usernames.
This is because I want to make the transition from dbmail to dovecot completely transparent to users and clients, and dbmail just uses plain login names, indepentend of what e-Mail alias would then in dbmail be mapped to which login name.
The plain solution above now works completely transparent for IMAP with dovecot, and it is also documented in the wiki that dovecot is domain agnostic. That is great news for my setup.
Where I am very flexible is delivering mail: I could use dovecot-lda or dovecot-lmtpd, or postfix doing the work itself or whatever. It is just that I did not find any solution, and this is why I was asking for help here.
So, is there a way for dovecot-{lda/lmtpd} to accept "user1@mydomain.org" but checks for "user1" in the user DB?
If there is some other idea, I would be happy to hear about it.
Thank you, again,
