Dean, perhaps I am not fully understanding your logic behind not closing
your relays.  I have been a systems administrator for 4 years and I have
not ever found an application where I needed to leave my SMTP relays open
to the world.  I do not doubt that you have legitimate business purposes
in mind when opening your relay, but at some point you must decide that
legal action will be too slow to fix anything and that it might be a good
time to close your relays to aleviate other problems.  Simply saying "I
shouldn't need locks on my doors because everyone should be
honest and never come into my house without my permission," dosen't cut it
in this world, and I am quite sure that you have
locks on every portal to your house, so why should your SMTP server be any
different?  Taking such a stance and refusing to close your
relays is simply a foolish decision.

Closing mail relays isn't very hard, and qmail and sendmail (and probably
the handfull of NT mailers) both have ways of implementing a
POP3-before-SMTP system so you can "allow" relaying from anywhere on the
planet without having to worry about abusers (as long as the abusers don't
have the login information for a POP box).  I suggest that you investigate
implementing POP-before-SMTP if you wish to leave your relays open to
everyone, as well as setting up RBL support on your server, in the end it
helps everyone by stopping one more potential spam outlet.

PS- and don't think that just having "private" IPs that are publically
accessible to the net will stop anything.  I use a cablemodem at home and
we have co-located equipment where I work, and it is constantly being
scanned for open vulnerabilities (including open SMTP relays, so you can
rest assured that someone will find you out sooner or later).

Inciting criminal acts is a criminal act too, I'm pretty sure. We make sure to mention them prominently.
