[Mailman-Users] Incorrect domain parsing?

Mailman ROCKS, this is a very well designed and thought out product, my
cudos to the developement team! Now on to my question. 8^)
Mailman seems to be munging the domain name, if I set the domain name to
'watcher' in the mm_cfg.py the From seems to reflect that correctly in
mail sent from Mailman but if I change the domain to
watcher.nsg.stercomm.com The From changes to the domain
watcher.stercomm.com. The problem is of course that there is no machine
by that name. I have experimented and read all I could find on the
subject and I can't seem to get this working.
Thanks in advance for any help you can offer.
