Good point. There are some definite header/body checks that are keeping some mail that are SPAM such as anything to do with certain drugs in the headers. This does have to be careful because thinking of blocking one word for SPAM and not recognizing that it can belong inside another legit word can cause trouble. Another desire is to not accept any mail attachment that has to do with images such as: gif,ps,tif,jpeg etc. from Debian mailing lists that I subscribe. Going back to 2002 when I started to use Debian I have not seen any reason to even accept a message with an image attachment from the lists. I would rather stop those mail at the door and not have to deal with processing time telling me it is SPAM as it is most certain to be 99.99%.

As for rules in spamassassin, can one write a rule after knowing it is SPAM (again some meds) and automatically delete them before they are sent back into the delivery cue?
