:No, actually, there is absolutely nothing which says that you, as a
:subscriber of good standing, *have* to be allowed to connect to
:non-local port 25. I think it is perfectly reasonable that the ISP
:require that you buy a static IP (with N months initially prepaid) or
:something to get port 25 privs.
ISP's have begun to do this sort of blocking because dialup spammers
abuse their privilages so much that a single spammer can cause an ISP
to get inundated with complaints, yet the ISP can do little about it
other then kick the spammer off (which solves nothing, really, considering
how cheap dialup accounts are).
Frankly, I have to agree that no dynamic dialup user should be allowed
to connect through to port 25 on anything but the ISPs own mail server.
