Disable response to specific query in BIND

[Sonorix]

Hi..

I'm trying to find a way to restrict response to specific domain query.

for example,
For the query about some hosts in "aaa.com",
I don't want to make recursive lookup for that domain, only
want to disconnect that requests or something like that.

Which is the best way?

For workaround, I made a zone file that have only loopback addresses for
all hosts and load it for some domains to get above goals.

Thanks.
