Hi, Just need a place to get some clue now. I have a functional ISPconfig3 installation with a few domains, tried to make a maillist with mailman from the frontend and never managed to get it to work so removed all config in the frontend and now the email-address in question "[email protected]" bounces regardless what I do. All other email boxes works as it should no errors what so ever. The mails to the address is bouncing with err: Action: failed Status: 5.1.1 Diagnostic-Code: X-Postfix; unknown user: "--censored--" and internally in the maillog it just says "bounced unknown user". The mailman list was deleted in the gui but seems to have failed, so deleted it with rmlist -a <listname> and no lists exists, still no luck. Anyone has some clue on how to proceed? I can't find where the issues lies at this time. Br/Joel
