Yes, I know. I've whitelisted most of the regular posters because
their messages ended up in my "held mail" folder on occassion.

I assume you meant "SpamAssassin scores". :-)
I have my SA filter at 4, which catches most spams. Some spammers
have taken to sending messages so short, that they don't trigger a
high score.
On the other hand, I recently received a spam with a SA score of 54.5!
The only messages that SpamCop drops are viruses. Everything else
goes to the user's mailbox for filtering based on the user's settings,
which may include "delete it".
SpamCop used to send virus e-mail notifications through to the inbox
(ie: "we filtered an e-mail with virus X in it", along with the
original headers) but they stopped doing that when one of the biggies
started causing some users to get hundreds or thousands of such messages
each day. (I wish they would implement an end-of-day summary with "we
filtered X virus-laden e-mails to you today" just for curiosity's sake.)
