Well in that case, don't serve anything from those masters! There has
to be some trust between the master and slave DNS servers and it looks
as though that trust doesn't exist for you. Too bad. So if you can't
trust some master server(s) to provide your server correct data, don't
serve their zones and get them to go elsewhere for slave service.
