Hi Robert, MD5 checksums will not work for slightly mutating content.
We need some sort of fuzzy signature to classify the spam. Also there
should be a very fast an efficient protocol to consult the central
for this "signatures".
IMHO I think it would be best to have the centralized server use some
bayesian methods trained by a collective set of users. Also I think the
best place to stop the spam is at the receiving smtp server, and it
stop at just classifying and stopping; it should also try to waste the
spammer CPU and BW resources, i.e.. like responding very slow if the
server is an black list or rejecting the spam before delivering it to
So what it would be great is to create rebol smtp-proxy to do the job
in coordination with the central server and training by the local admin.
My two cents,
