Hello Mohammed,
I don't see that you specified a "response-policy" [1] statement. You need
something like this as well:
response-policy {

RE: scripts-to-block-domains
Hello all,
Thanks for every one's contribution. I use RPZ and listed 5000 forged
domain to block it in a particular zone without having addiotnal zones, I
hope that's the feature of RPZ, Seems good.
Below is snippet for your review for the zone and file db.rpz.local which
was copied from the default named.empty.
zone "rpz.local" {
type master;
file "db.rpz.local";
allow-query { localhost; };
};
Once this configuration done I am expecting that whoever quarried to our
name server for a zone which Is listed in my dns server should not allow
users to fetch any records as recursive from outside servers, it should
server from the internal servers only?
When I test my configuration with one of the hosted domain in my list i.e
doubleclick.net, I got all the results rather than throwing an error. please
correct if I am wrong..
Here are the logs.

$RPZ++
If you can't use RPZ, then you /can/ create skeleton zones to make your
server authoritative for the zones in question. However, there are
drawbacks to this regarding performance based on the number and size of all
the additional zones.
I would strongly recommend RPZ, or the new Response Policy Service, which
there are a few commercial implementations of. RPS is for DNS what milters
are for mail servers.
RPZ is a ""static list.
RPS is an active / dynamic service.
Note: Response Policy Zones can be updated via normal dynamic DNS methods.
