Spamhaus DROP - [D]on't [R]oute [O]n [P]eer list
http://www.spamhaus.org/drop/

"When implemented at a network or ISP's 'core routers', DROP and EDROP
will help protect the network's users from spamming, scanning,
harvesting, DNS-hijacking and DDoS attacks originating on rogue netblocks.

Spamhaus strongly encourages the use of DROP and EDROP by tier-1s and
backbones."

This is not a valid use of DROP.  Someone upstream of you is already
taking care of DROP long before such packets reach your MTA.  The DROP
list is for use by infrastructure providers, not end users of networks.

You are simply wasting your time with this.  It will stop no spam.
Forget it and move on to something that will actually be of benefit.
