dropping based on attachment code signatures

[Michael Masse]

I haven't been able to find out in the documentation or list archives if it's possible to have MS scan for a code signature and if a match found, drop the email?    I have a procmail script that is currently doing this, but it's really inefficient since MS passes the email to the script only when it's done and has reassembled the email back together again, so the procmail script has to tear the email down all over again.
