    Don't forget that some spammers use legitimate SMTP servers to send spam;
    if someone sends spam from a shared server, you could be preventing tens,
    hundreds or even thousands of users from sending their legitimate non-spam
    email.  More importantly, doing so could make an ISP consider it a DOS
    attack, call YOUR ISP, and get YOU kicked off.

Um, how could passively hanging a connection _initiated by the other side_
be considered a DOS attack?

Sure, if *I* initiated the connection, it might be DOS, but these are
_incoming_ connections from the other site.
