Problems with MX records?

[Mark_Andrews at isc.org]

	You are attemptig to configure a CNAME and a MX record
	with the same owner name.  The following for RFC 1034
	explains why this is not allowed.

The domain system provides such a feature using the canonical name
(CNAME) RR.  A CNAME RR identifies its owner name as an alias, and
specifies the corresponding canonical name in the RDATA section of the
RR.  If a CNAME RR is present at a node, no other data should be
present; this ensures that the data for a canonical name and its aliases
cannot be different.  This rule also insures that a cached CNAME can be
used without checking with an authoritative server for other RR types.
