[Pdns-users] MX query not returning MX record

[Dan Durrer]

I understand why this doesn't work.  But have you guys thought about
making some type of scripts for adding/updating records and such.  This
way there can be some sanity checks that would follow the rfc's etc
insuring that bad data doesn't get into the db.  We will probably be
developing these for our system, unless there are already tools out
there.

Indeed - you have a CNAME-and-other-data situation. Don't do it. Remove
the domainofdarkness.com CNAME to pod and things will work.
