BIND 9.6 Flaw - CNAME vs. A Record in MX Records are NOT "Illegal"

[Ben Bridges]

The authoritative name servers for nullmx.domainmanager.com are
ns1.domainmanager.com and ns2.domainmanager.com.  They are domain
parking name servers.  They return 64.40.103.249 (or at least something
close to that) to the query for any A record.  The real address of
mta.dewile.net is 69.59.189.80 (as supplied by ns1.alices-registry.com,
one of the authoritative name servers for "dewile.net").
