Re: Question of Firewall & Mail Servers
Doug, look into IPPORTFW (if you use a 2.0.x kernel -- ipchains has it
built-in for 2.2.x IIRC..) -- it will let you specify that port 25 of your
firewall forwards directly to the smtp port on your mailserver.
The IP-MASQ howto has much good info on this sort of stuff. :)
