Same here, I only see a handful, and this is for a relatively old email 
address which has been used in newsgroups (including antispam ones which 
makes it a real target). Most of it is deleted server side.
It is this remaining few messages which I can't see any means of filtering. 
I suspect there are many more from the same addresses which I never see 
because they get blacklisted fairly quickly, but they have to be used for 
spamming before that can happen.
Can't filter by origin because they come from random compromised machines.
Can't filter by Subject: because they use random words.
Can't filter content because they use images. Ok I could filter to text 
only, but the number of these things I get doesn't justify the risk of false 
positives.

(It's mainly one pump & dump stock spammer, with the occasional Viagra 
merchant)
