I have a curious situation. I could fix it, so there is no hurry to find a better solution, but I wonder where I failed :-).
I have a domain name (culte.org) that hold a mailman mailing lists server.
Under this domain, there is a (virtual) network. The real server is savage-reborn.culte.org
When mailman send the messages to the lists, no problem at all, the return path is <list-name>@culte.org
but when mailman send the monthly reminder, the return path is <listname>@savage-reborn.culte.org.
some recipients do not like to have the extra "savage-reborn" part and refuse the mail.
I don't know where I could change this without disturbing the server's working.
The MTA is postfix.
I could solve the problem adding savage-reborn in culte.org zone definitions.
any idea?
thanks jd
