If you are looking to filter before you download the message, the answer is 
no, to my knowledge.  Before you download the entire message, there is no way 
to know if there is an attachment or not, the headers do not tell you that.  
You have to filter after downloading the body.  You can filter before it gets 
to your inbox though.

Or, if you have a shell account at the ISP, you can run spamassassin or 
procmail there and delete from the mail server but it will still get to their 
machine.
