I use Trend Micro's PC-cillin 2007 Internet Security which includes a
spam filter.
At the beginning I had to "unfilter" one or two valid senders, by
today I don't
bother to read anything in the spam folder, I just delete everything.
Between it and Outlook built in Junk-mail filter I see maybe 5 spam
messages a week
(there could be 60-90 of them a day).

Ed,
Nobody is ever going to accuse me of being the master about this
subject. ^_^
But I would do the following:
1) Get a Bayesian filtering program. (I use K-9.)
2) Never use anything that produces bounces.
3) Use a whitelist.
4) Use a blacklist, too.
Generally, my combination gets about 99.75 percent correct. Yes, I
get some false negatives (SPAM that is not identified as SPAM). More
rarely, the false positive (identified as SPAM that isn't).
But all the identified-as-SPAM mail goes to the trash, where I can
analyze it in seconds.
"Unprotected", I don't know. But bouncing SPAM email is a no-no. You
are bouncing messages to people that had *nothing* to do with the
original message. Much better to silently accept, filter, and
dispose. Never, ever, acknowledge receipt of SPAM. A bounce, should
it even go to the true sender (highly unlikely), would do just that.
Simply ignore. Delete and forget.
Bayesian filters are impossible to defeat. They can be circumvented,
temporarily, but they "learn". Every time they mess up, you teach
them. They get "smarter".
