just taking this thought of DNAT (iptables jargon) a little further,
one might even let sendmail run on, say port 1025, 2525, whatever,
and use iptables' REDIRECT target (or whatever insert-your-favorite-os
gives you similar) to redirect traffic destined for port 25 on the
local box to the port sendmail is actually running on.

just my 2 cents


have a nice day :-)
