   sbl.spamhous.org will return 127.255.255.254 to indicate an invalid query,

   Also, something seems to be awry with IPv6 lookups since I get this:   
   `X-DNSBL: 2610:1c1:1:606c::19:2 is listed on sbl.spamhaus.org       (see   
   http://www.spamhaus.org/) as 50.16.218.27`, but a manualy lookup shows   
   NXDOMAIN:
