[Mailman-Users] postfix + mailman, bounce detection not working?

i have no idea whats going wrong:

i have lots of entries in ..mailman/logs/smtp-failure like this:

Jan 27 22:26:39 2004 (29932) delivery to public@sushu.net failed with code 450: <public@sushu.net>: Recipient address rejected: Domain not found

since weeks now every 15min (!)

i am using postfix as MTA.

any ideas what may go wrong? is this not a case for bounce processing? i checked, the bounce settings and anything seems to setted correctly.

everything else is working perfectly!

any hint would be very appreciated...

greetings, robert
