ok, the firewall is not proxying POP, since POP is not normally used in mail abuse. SMTP is. >So, I can conclude that my firewall is doing something wacked out. wrong. Your firewall apparenlty defaults to proxying SMTP.

NAT alone won't. It's the SMTP proxy that is taling to internet, not your Imail SMTP server. > If >it is, there isn't anything else I can do at this point because the way >things are currently set up, the mail server MUST be inside. ok, inside isn't the pb, SMTP proxy is. >Ah well, live and learn! yep.
