Ignoring unqualified MX's ?

[torben fjerdingstad]

One of our customers has had a lot of mail loops because
a spammer has this in his return-path:
Return-path: info at internet.net

The problem with that is:

$ host -t mx internet.net
internet.net            MX      5 localhost

Is it possible to make bind discard that information without
creating a local master zone file for the bogus zone?
