Flashlight spam (and others)

[@lbutlr]

I keep getting a rash of multiples of flashlight spam and gift card spam, all of which go sailing right through amavisd/postfix. Has anyone figured out a way to have amavis be more aggressive in tagging spam like this? Obviously BAYES_00 doesn't help, but even without that this spam would not have gotten tagged. There are hundreds of these hitting the server every day. and dozens just to me.

I run these through sa-learn but the bayes score never changes.
