I use postfix + dovecot LDA + mysql virtual users and up til friday, everything was working just fine.
Dovecot is 2.0.beta6 (3156315704ef)
Like I said, up til friday, when I added a vacation entry into postfix (which I have now removed to see if it was the reason) mails to the alias virusalert (which is aliased to me) went through just fine.
Now I get these sort of errors from the LDA:
Feb 27 11:54:03 cluster2 postfix/pipe[31267]: 866F0A41173: to=<virusalert@mobilia.it>, relay=dovecot, delay=357414, delays=357413/0.79/0/0.05, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Fatal: Unknown user )
Other aliases work perfectly, the only difference is that these emails are of local origin, (they're messages from Amavisd) I'm not sure why this has started to be a problem.
Can anyone give me an idea where I should start looking?
