[Dovecot] DOES NOT PERTAIN TO DOVECOT: Does anyone use postfix for some help?

[Jerrale Gayle]

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.
