-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ...ok, I have located postfix written by Wietse Venema. This seems to do what I want, however, it opens port 25. When I scan my ports, I find port 25 is indeed open. I am not certain what I need to do to filter this port. I still have not gotten a handle on iptables and it has been some time since I have played with ipchains. Does anyone have any experience with such, I would appreciate suggestions. Thanks.
