We just put a one line entry in our startup scripts that allows connections
from port 26 to redirect to port 25. This way customers who are blocked by
their ISPs on port 25 can still connect to our SMTP server. But you can use
any port and as many of these lines as you want.
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 26 -j REDIRECT
--to-ports 25
