Right, I don't care.  I just want to get root's emails out of there.
Basically I'm trying to send root's emails outbound from the gateway
through the internal interface to my internal mail server.  The gateway
uses my internal name server to resolve names, so nothing should even be
going out the external interface of the box.

Yes.  I can ping localhost.visimation.com and it comes back just fine as
127.0.0.1.

Right.  Exactly.

> Can you telnet internal_mailserver 25?

Yes I can telnet to it from the gateway.  Definately my internal mail
server is not the problem, as it is working normally.

> Does it work if you turn off NAT and the redirect?

Nope.  I flushed all the rules, my ipnat.rules in empty and my ipf.rules
is pass in all and pass out all.

Nope.  Just the same things.
