I would be asking him why www.mca5.com is still serving a
old copy of the zone.
If you are using a forwarder and it is old enough you may
be being affected by the issue addressed by change 619.
This is only a problem if the zone is being miss managed
by allowing multiple different versions of the zone to
exist as is the case here.
