.rp,

Use the backscatter messages to train bogofilter.  With enough of them
trained as spam, bogofilter will start to recognize their distinctive
words and, after a while, will start to classify them as spam.

I started that training a while ago and bogofilter now classifies most
such messages as spam.  The ones that it misses are used for training.

HTH,
