Default Mail-Catchall and forwarding stopped working


since today my server isn't forwarding emails anymore (worked for month now). Also catchall isn't working as well.

All message get bounced fromdovecot, but from what I've read so far postfix should forward the mails itself and dovecote shouldn't even be involved?

From the log:
 relay=dovecot, delay=0.27, delays=0.25/0.01/0/0.02, dsn=5.1.1, status=bounced (user unknown)
  • It doesn't matter who the sender is (internal or external)
  • The (forward) recipient doesn't matter as well (internal or external)

What I did today with the server:
  • Installed Roundcube (had nothing similar before)
  • Did an ugrade of installed software (clamav received an update)

I also compared the configuration files with a backup from last week and didn't find any noticeable.

Now I already spend hours to figure down the problem. I hope you have some tipps, I really want to avoid reinstalling the whole server.

Is there a way to figure out what postfix is doing and why it is not correctly forwarding mails or is it really a dovecot problem?

My installation is http://www.howtoforge.com/using-roun...wheezy-apache2

Okay, just solved it (at least for now), with the solution from here: http://www.howtoforge.com/forums/showthread.php?t=36419
  • Remove amavis
  • And set "no_unknown_recipient_checks"

I still don't know why this caused the problem. Maybe someone knows more.
