[Techtalk] multiple domains, single server

[Rod Roark]

Regardless of what you put in the headers, anyone who cares 
will do a reverse lookup on the IP to see where it came 
from.  Forging it will just make you look like a spammer
(are you one?).

What I would do is put the mail server on an IP that 
corresponds to a generic-sounding domain name.
