Well, I run a small ISP with about 3,000 mailboxes, we receive about
50k messages per day.  Of that, on average 39-44k are blocked by SA
for scoring 6+ points.  From what slips in, I created a simple VB
program to use spamassassin to scan the messages sitting in the
inboxes. In the last few days of running, it's identified 12,404 spam
and 72,520 ham.  Since the spammers make huge runs and then change or
disappear for a while, I needed a method to clean my maildir almost
like real-time virus scanning.  Except I'm just running my scanners on
free CPU of various workstations, if my program ID's spam in someone's
mailbox, it removes it and I verify it and add to my corpus.

According to my numbers, about 17% of mail passing SA is considered
spam by the time I'm done writing rules after it's already entered my
system.  I block at 6.0 and use no RBL's.  I do write custom rules
daily.
