Running on anything other than port 25 is pretty silly considering that all
applications and all mail relays attempt to deliver to port 25 on every mail
server in the world...Internally, you could do it, but why?
If you need to proxy port 25 to some other port, try searching on freshmeat
for redir (what we use). We have one machine here which our router routes
all internet viewable IP addresses to (it has an internal IP address which
the router refers to, and the ethernet interface accepts packets for all the
IP addreses we use (running Linux). ie eth0 would be 10.0.0.2, eth0:1 would
be 99.99.99.1, eth0:2 would be 99.99.99.2, etc), and we can control what
ports on what IP addresses go where internally (so everything else is
virtually closed and secure). This also means that if we need to change a
machine's functionality or move a mail server to a different machine, we can
simply change an IP address on our port forwarding machine and its done - no
external DNS and TTL hell to live through... You COULD alternately try
ipmasqadm with ipchains but I haven't had any luck with port forwarding this
yet...
