Judging by recent spamassassin-users mailing list messages, Verizon is  
hijacking DNS responses that seem to be invalid and replacing them  
with their own responses (in oder to drive traffic to their search  
sites).  Naturally this breaks SURBL lookups.  If you are using  
Verizon's nameservers and are getting false positives, you may want to  
check into this.

Here's one reference:
