If you turn on ORBS in sendmail.cf, 99.9% spam will be rejected.
We use it at Cygwin mailing lists. It does have a disadvantahe many
ISP who run lousey OpenRelay systems, their users could not post,
but then when their users yell at them some of them fix the OpenRelay
loopholes. Most fo the Open Relay are at academic institutions. Japan
is the Open Relay beast. Looks like 80% servers in Japan are Open Relay

At one point, at our company we had all the domains ending with *.jp blocked
and allowed only select e-mail addresses.
