Thanks, Dan.
I think I understand now.
Restrict_post and Reply_to are absolutly correct set and are not the reason for our
problem. It's that alias address that shows up in a "Received: from" section of the mail
header.
Here's an excerpt of a typical newsletter mail from our list-server:
Return-path: <owner-gtt-news@gttserv.lth.rwth-aachen.de>

X-Authentication-Warning: gttserv.lth.rwth-aachen.de: mdom set sender to owner-gtt-
news@gttserv.lth.rwth-aachen.de using -f
Date: Thu, 15 Jan 2004 16:24:29 +0100 (MET)
From: sp@gtt-technologies.de
Subject: GTT-News, Issue 38
X-Sender: sp@gtt-ws7.lth.rwth-aachen.de
To: GTT-News@gtt-technologies.de
The insecure address we're talking about is gtt-news-list@gttserv.lth.rwth-aachen.de.
Normal action on a mail like the one above would never result in sending a mail back to
this address.
We're using Suse Linux 8.0 on our server, which installed Majordomo and sendmail with
standard configuration.
I know, what you would say now: Never use standard configuration, since it is a
compromise to all possible users!
I will now try to understand the current config of our sendmail and it's mail address
aliases and figure out how to change it to meet our requirements.
Since I never worked with it before, it looks like it's getting to be a very time consuming
process ... :-(
Thanks again for your help.
Best regards
