[ietf-dkim] Are lookalike domains like parent domains?

NXDOMAIN (RCODE=3) means the name does not exist in DNS.  NODATA 
(RCODE=0 + ANCOUNT=0) means the name is valid but no records of the 
requested type were found.  We're only interested in the first one.

So, our side in the debate is not operating from a misunderstanding of 
DNS as far as I can tell.
