You need an SMTP process running on port 25 to accept incoming mail
from other hosts, but there's nothing to keep you from running a second
daemon on whatever port you want.
So you set up your normal (non-relaying) server on port 25, and a
server that will relay given the correct MAIL FROM on port 2500 or whatever
you want. Then tell the users you want to be able to use that relay to use
the SMTP process at port 2500 or whatever when they send mail.
