They made it impossible to use port 25 at all, since it's impractical for
ISPs to sniff outgoing traffic to permit SMTP AUTH connections and block
others, and way too much of the other port 25 traffic was
direct-from-dialup spam.

SMTP AUTH works fine on port 587, since there should be no traffic to that
port that isn't authenticated somehow.
