Exploit?  How about mis-tag?

I just looked back thru' my collection of legitimate mail and I have
lots of goodmail items from ebay and paypal.

Whitelisting Froms isn't a bad idea.  Blacklisting From domains seems
like an idea fraught with the possibility of false positives.  Then you
get to deal with what you do with your positives and how much you like
digging thru' your spam to find the occasional false positive.

Sometimes having a bright idea about how to block something isn't such a
bright idea after all.  My experience with phishes is that they are
mostly sourced from listed open proxies.  I would much rather tag as
spam something coming from an open proxy than something coming from a
paypal or ebay.address.

I think the best kind of filter is one which never has a false positive
ever, even if an occasional spam leaks thru'.  Creating a filter tag
which might possibly have a false positive is not a good strategy in my
opinion.
