You need to make arrangements with someone with a mail server that will
listen on another port. I do that for all my traffic, route my home
office cable mail via my outside commercial unix mail server.

That server using Exim listens on both 25 and 2025 for smtp traffic and
knows that anything routed back to my home server needs to go via 2025.
