Don't know ipchains well enough yet to give you commands, but to send
mail you need to open up port 25 (SMTP) with TCP protocol from your
internal to either a specific external (if using an external smart host
for relaying) or to all addresses.  I just re-did this recently with
Novell Bordermanager, and one thing I had to go with Novell's IPFLT was
to make certain I had both an incoming and outgoing filter, so that the
2-way conversation was possible. Don't know ipchains well enough to know
if you have to do something similar.
