RE: Changing the outgoing hostname in message headers

Thank you, men. I confess that my Postfix skills weren't up to handling multiple instances or master.cf hacking, but we did have another domain sitting idle which now serves as the bland mailserver hostname. Its presence in the mail headers won't cause problems for any of the three companies.

We're using Postfix 2.1.5 on an old Debian 5 Linux system as an incoming, but not outgoing mail server. (We host several domains on our server and don't want the mail headers for outgoing mail from (say) CompanyA.com to say that they originated from a hostname that might be CompanyB.com, CompanyC.
