answering my own question; is this what i need to change ? http://www.postfix.org/postconf.5.html myorigin (default: $myhostname) The domain name that locally-posted mail appears to come from, and that locally posted mail is delivered to. The default, $myhostname, is adequate 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. Example: myorigin = $mydomain okay part (2) of that answer set up a domain-wide alias database that aliases each user to user@that.users.mailhost how do i do that properly ? -j
