Please see <https://wiki.list.org/x/12812344>. Then contact RedHat about
what appears to be a bug in their mailman-2.1.12-26.el6.x86_64 package.

I suppose it's possible that Mailman is adding the Reply-To: and the
outgoing MTA is removing it, but in any of our Mailman 2.1 distributions
since 2.1.1 the above settings will result in

Reply-To: redacted at mailbox.tu-berlin.de

being added to the outgoing message.

You could look at your Mailman/Handlers/CookHeaders.py in the section
that begins with the comment

    # Reply-To: munging. ...

to see it it looks correct. In particular, this

        # List admin wants an explicit Reply-To: added
        if mlist.reply_goes_to_list == 2:

is what puts reply_to_address in the Reply-To: header in the outgoing
