As a metric of a well run system checking that there is consistency in
the DNS/rDNS is good but this needs to be a full check where

nameA --> IP --> nameB
           ^      |
           +------+


where nameA and nameB are not necessarily identical but given the number
of badly run sites out there you'll throw a lot of good email away with
this check.
