More than five is a bad week for me.  I use:

1) strict DNS checks (matching forward/reverse)

2) my homegrown sendmail access file and regex maps
   to detect and reject dynamic ip ranges, based on
   host name (works because #1 strictly enforced)

3) a few key blacklists:

dynablock.njabl.org
dnsbl.njabl.org (127.0.0.2, 127.0.0.4, 127.0.0.8, 127.0.0.9)
list.dsbl.org
sbl-xbl.spamhaus.org (127.0.0.2, 127.0.0.4)
bl.spamcop.net

I estimate 70% or more SPAM is stopped by #1 and #2, thus reducing the
blacklist query load.
