Actually I figured out how to use it to my advantage. I query "." which 
is my own DNS server of course as a ip4r blacklist and if the IP for 
verisign's site is returned then I give the spam a very high score. Any 
domain that doesn't exist would fail this, but any other domain would 
not return that IP, but rather the proper IP.  I'm still pissed at 
Verisign, but I always try to turn a problem in to an opportunity so 
now I'm using their greed to block spam.
