I have a little issue with all my mailing lists. For every mailinglist there is always one fixed user (in the sample below email@example.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) (firstname.lastname@example.org) (envelope-sender email@example.com) by smtp.provider.com (qmail-ldap-1.03) with SMTP for firstname.lastname@example.org; 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?
A month ago I asked privately about this (on behalf of a friend's list which arrives in my inbox in this fashion) and was told:
It's definitely being added by some MTA in the chain. Mailman never touches the Received headers.
On my friend's list, the "one user" differs somewhat from mailing to mailing (the list sends out small clusters of newsletter posts every few weeks), so I have a handful of email addresses I've received in the headers of posts from that list.
