I get a bunch of mail on about 20 different servers that I'd like to get to one. The boxes are running Linux and right now my solution is to create a TCP relay.
I want anytime traffic coming in on port 25 for it to be relayed over to a box somewhere else not on the same LAN. I have a Perl script which does roughly this but it's inefficent and can crash. I'd rather find a way using iptables/ipchains if there is such a way. I think there is but I don't have the technological skill to understand it.
