This will do what you're looking for, much easier. in main.cf:
mydomain = arlut.utexas.edu # SENDING MAIL # # The myorigin parameter specifies the domain that locally-posted # mail appears to come from. The default is to append $myhostname, # which is fine for small sites. If you run a domain with multiple # machines, you should (1) change this to $mydomain and (2) set up # a domain-wide alias database that aliases each user to # user@that.users.mailhost. # myorigin = $mydomain Best, --Glenn
