we do it here, for DLP.  we can 'tag', whitelist, blacklist, or quarantine.

start with an amavisd.custom
change %Amavis::Conf::subject_tag_maps_by_ccat and 
Amavis::Conf::quarantine_method_by_ccat (unless you never need to 
quarantine by cat)
know what your rule will add to X-Spam-Status

look for that in sub checks() and sub before_send() (if you need 

do magic, including putting [CONTENT] in Subject line on inbound (like 
[SPAM] in subject in inbound)

can I share EXACTLY how I did it?

no, not really.  but this should get you started.
