Greg,

A simple answer to remove most of your spam at server level is to use some
of many good blackhole lists that verify open (insecure) relays, and
qualified spam senders then put them in a DNS type list that your mail
server can query.
If your using sendmail then you can just add the following into your
sendmail.mc:
FEATURE(dnsbl, `blackholes.mail-abuse.org', `"550 Mail from "
$&{client_addr} " rejected, see http://mail-abu
se.org/cgi-bin/lookup?" $&{client_addr}')
FEATURE(dnsbl, `relays.mail-abuse.org', `"550 Mail from " $&{client_addr} "
rejected; see http://mail-abuse.o
rg/cgi-bin/nph-rss?" $&{client_addr}')
FEATURE(dnsbl, `dialups.mail-abuse.org', `"550 Mail from dial-up rejected;
see http://mail-abuse.org/dul/endu
ser.htm"')
