How to get the rules from MYSQL DB

[ma...@sbgit.com]

Hi there,

i want to store my rules into an mysql DB, but how to say 
spamassassin get them from the mysql db?

There existing solutions for user_scores and awl, but i
can't find nothing about the rules.

I can't use Maia or something similar, because my system
is just an Mailrelay with spam/virus filtering functions.
So there aren't any mail accounts on it.

Thanks 
Peter
