[Mailman-Users] SMTP Problem

[Fuss, Christian]

Hi,   i do have a really urgent Problem with my Mailman. Actually everythings working fine except of sending the mails to the list-members. I get following failure in the smtp-failures log:   Oct 12 19:49:11 2002 (2292) delivery to [EMAIL PROTECTED] failed with code 553: 5.3.0 <[EMAIL PROTECTED]>... No such user here what might be a problem is, that i have activated smtp auth for preventing relaying.   can anybody help me? thx Christ
