If someone gets a moment-- he/she should add gross to the postfix policy
page: http://www.postfix.org/addon.html
Homepage URL:

From page description:
* it's blazingly fast
* it's amazingly resource efficient
* it can be configured to query DNSBL databases, and enforce greylisting
only for hosts that are found on those databases
* it can block hosts that match multiple DNSBL's
* it can be replicated and run parallel on two servers
* It supports Sun Java System Messaging Server, Postfix, Sendmail and Exim.
I have been using it for a month or so now alongside policyd-weight,
postfwd, etc and find it quite useful.
