When mail is sent from the mail server, it shows up as originating from the MAIN ip address of the server, 173.50.101.11, when the mail server is bound to 173.50.101.12. I have already set smtp_bind_address: 173.50.101.12 in main.cf and 173.50.101.12:smtp inet - - smtpd in master.cf. This prevents smtp connects TO any other ip but 173.50.101.12 BUT mail STILL shows up originating from eth1, where 173.50.101.12 is eth1:2

I think this is *nix related and most here, on dovecot mailing list, could provide help.

DOES NOT PERTAIN TO DOVECOT:

Correct.

Dovecot does not send email. You should probably get on the list for the MTA software you are using.

A similar thread just went on on the Postfix list. I didn't follow it but you can check the list archives.
