I did not see an answer posted, but all mail sent out between severs such
as sendmail require port 25 and a reject or an ident server

I have built a firewall for a 50 node network using ipchains. The firewall box
Masquerades out the internal network, numerous services function
wonderfully and nothing unwanted gets in. The only problem is that NO mail can
be SENT internally or externally. Receive mail uses pop-3 and is spiffy
