Wrong glue records entered.

Are glue records supposed to be returned with the MX records?

The problem that we are having is that someone will create the following MX
records for their domain.
@             10800   IN      MX      40 smtp.secureserver.net.

But then some one else will create the domain "secureserver.net" in our system
and point the A record for "smtp" to another IP.
Now "secureserver.net" is not pointing to our name servers (at the root name
server level) so our servers should never be asked for it.  But they are by
some resolvers and it is poisoning everything.

When I do a "dig" I do not get this problem at all (that the glue records are
being returned since the server is not responsible for that zone).
I have tested this with both bind (9.x) and dnscache and neither do this.
But some name servers are asking for these records.

Is is possible (other than deleting the "secureserver.net" zone) to stop these
resolving name servers from asking our name servers for domains that it has no
business asking?

Thanks for any insight,
