[Mimedefang] RBL suggestions

[WBrown at e1b.org]

I am looking to start using an RBL.  In the past, a colegue did some 
testing of RBLs and got a lot of false positives. 

I am looking for recommendations for a high quality RBL (preferably free, 
we're a K-12 educational organization) that is very low on false 
positives.

Also, is there a way for a milter to detect a black listed host and tell 
sendmail to close the TCP connection on the spam sending server?
