That is a good starting point for writing a plugin to do something
similar but the OP wants to hash the subject not the body. I started
doing this a while ago in addition to using ixhash. After engineering a
Client-Server plugin to provide realtime hash stats it helps to push
spam over the threshold without having too many false positives. The
false positives I received were typically monthly notices like the
Verizon Wireless statement notice that hit thousands of boxes at the
same time.
I strongly recommend being careful with the scoring of the subject hash
and be sure to account for missing subjects. I find a missing subject
is more common in ham than spam.
