Are any others being affected by the fools who have registered "com.co.nz"?

It's been setup as a 'catch all' search engine, for the 'append parent DNS suffix' queries. So a lookup on "abcd.com" that should fail, comes back successful from "abcd.com.co.nz"... :-(

I add a line search . in /etc/resolv.conf in my mail servers to fix this sort of stuff. All email addresses should be fully qualified. Regards, RH.
