I think you really are talking about punching a whole in the firewall.
On any distro with a kernel >= 2.4.x, this is done using iptables.
You'll need to learn how to manipulate iptables. For now, just turn off
the firewall altogether. You'll need to modify sendmail's configuration
to allow inbound connections, though.
The port itself is opened by the smtp process itself. It really has nothing to do with the firewall, except that the firewall needs to be told to allow traffic through to that port. Anyway just a terminology correction.
Michael
or any ports for that matter?
