Nice howto. It help me also with a second problem, what occured when i was investiaged the lost mails.

I own a domain with the name sv-og-wertheim.de. This mails are also collected by fetchmail and forwared to the local user. But the users never get the mails

The following show you the log after the message come back from amavisd:

All other mails are forwared without any problems. Attached are the relevant part of the postfix.log

I thought it will be the same, like when clamav is not running. So the message is qued until clamav is back. And SMTP will warn the sender after a while and not directly.
