But he wants a second port on the same interface. He really needs to upgrade to
Exim 4, which allows multiple port connections to be specified (as well as
multiple interfaces, if desired).
I should point out that there are already a couple of ports reserved for email, in
addition to port 25. Check your /etc/services file for "SMTP" and "mail" to get
an idea. Might as well go with standards, rather than willy-nilly picking random
ports.
I, for one, remain appalled at the idea of hijacking ports. But the ISP
motivation is strong; they are trying to block spammers from abusing ISP
bandwidth. Nevertheless, the ends do not justify the means.
