This is not random, some addresses pass always, others fail reproducible. In my opinion there is only one thing which could cause this problem: I updated my dovecot on 2013/11/04 from 2.2.6-1~auto+36 to 2.2.7-1~auto+2 I updated two days ago. I will try to downgrade again, did someone have a clue? I have no clue what leads to those random rejections of recipient addresses.

Dovecot debug logs rarely help with any random problems you have, they’re mostly there to find out configuration mistakes. More interesting would be to know if you see ANY error/warning messages in Dovecot logs (Fatal, Panic, Error, Warning). You’ll also see the last 1000 error messages since dovecot started with “doveadm log errors”.
