See if this at least gives you a start on the project:

http://www.ijs.si/software/amavisd/amavisd-new-docs.html#score_sender
also helps explain SQL w/b lists.

Keep in mind not all user_prefs settings will carry over. The most
critical will, the ones shown in the SQL fields.

Since amavisd-new only calls SA once for a given message regardless of
the number recipients, and it has the ability to cache previous results
for messages with identical body, it is often more efficient than
spamc/spamd. The amount of memory used is controllable, but should be
tuned to match the power of your CPU(s) and throughput needs.
