Cyrus IMAPd + SIEVE
Okay, I’m much further now. As I stated earlier, Cyrus is working now and Postfix is actually delivering the message to the correct queue. So now I can mail myself. Next step.
Since we need Squirrelmail together with avelsieve, the SIEVE plugin for Squirrelmail, I installed those and they seem to work. Seem, because I setup a vacation-message in avelsieve for my user and it didn’t trigger or at least didn’t send me a message back when I mailed myself. Ah well, next problem to fix. Ideas are welcome, of course.
