list reply domain mangled
I have a aaa@yyy.zzz.ucla.edu, but when an email is sent out, it appears to come from aaa@zzz.ucla.edu. Only an explicit reply-list works, and then not all the time.
I should note that the server is not virtual, and doesn't have any other names beyond yyy.zzz.ucla.edu. DEFAULT_URL_HOST & DEFAULT_EMAIL_HOST are explicitly defined that way anyway. The individual lists have th host_name properly defined as well.
Even reply-to header munging (first_strip_reply_to, reply_goes_to_list, & reply_to_address) are ineffective at preserving the yyy portion.
At this point I'm guessing MTA somewhere is changing all this, but where? The MTA in the box is sendmail, but as for the rest of the network...
Thanks, Ryan

Does sendmail deliver directly to the recipient MX or does it relay through another host in the local (ucla.edu) network? The Received: headers in a message will tell you which MTAs it passed through. It is almost certainly some MTA in the ucla.edu if not in the zzz.ucla.edu domain.
Since 'reply list' works sometimes (I'm guessing when it doesn't, it isn't offered because you are looking at a direct Cc:, not a list copy), the List-Post: header is correct, so Mailman is doing the right thing and it is a downstream MTA that is munging From: and Reply-To: domains.

Most list members have addressed zzz.ucla.edu, but those who are external (like gmail) always get proper yyy.zzz reply-to domains.
At this point I'm guessing MTA somewhere is changing all this, but at this point I'm definitely out of my element. The MTA on the box is sendmail, but as for the rest of the network...
