[Mailman-Users] Mailadress in Header

[Christian Vierkant]

Hello,

I have a little issue with all my mailing lists. For every mailinglist 
there is always one fixed user (in the sample below 
some.user at somewhere.com) appearing in all outgoing messages.

We are using Mailman 2.1.2 with Postfix 2.0.14. Here a sample from a 
mail sent to a different user than in this header:

[...]
Received: (qmail 17852 invoked from network); 9 Jun 2005 06:45:29 -0000
Received: from unknown (HELO mailmanserver.somewhere.com) 
(123123@[111.111.111.111])
          (envelope-sender <list-bounces at somewhere.com>)
          by smtp.provider.com (qmail-ldap-1.03) with SMTP
          for <some.user at somewhere.com>; 9 Jun 2005 06:45:29 -0000
Received: from mailmanserver.somewhere.com (localhost [127.0.0.1])
    by mailmanserver.somewhere.com (Postfix) with ESMTP
    id 0C14870BF; Thu,  9 Jun 2005 08:45:29 +0200 (CEST)
[...]

Does this look like a mailman, postfix or provider problem?

Thanks,

Christian
