If I read that warning correctly, it is simply telling you that the email address Christian@malibu-2002.de is bouncing.

What happens when you send an email to "Christian@malibu-2002.de"? Does it bounce? Are only Mailman messages bouncing to that address?

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 Christian@malibu-2002.de failed with code 553: 5.3.0 <mailingliste-bounces@malibu-2002.de>... 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
