For some reason RPZ rewrite on my setup kept failing dns querylog show the following:

Apr 18 12:26:28 Internal-DNS-DHCP named[7257]: client 172.16.11.17#58306: rpz QNAME rewrite gateway.fe.apple-dns.net via gateway.fe.apple-dns.net.rpz.local.net query_getzonedb() failed: zone not loaded
Apr 18 12:26:31 Internal-DNS-DHCP named[7257]: client 172.16.10.13#64377: rpz QNAME rewrite teredo.ipv6.microsoft.com via teredo.ipv6.microsoft.com.rpz.local.net query_getzonedb() failed: zone not loaded

The error is: query_getzonedb() failed: zone not loaded

The Fix:
1. Check your Bind DNS startup log:
Apr 18 12:39:23 Internal-DNS-DHCP named[7551]: zone rpz/IN: loading from master file /etc/named/zone/response-override.db failed: permission denied
Apr 18 12:39:23 Internal-DNS-DHCP named[7551]: zone rpz/IN: not loaded due to errors.

2. Fix Zone File permission error.
3. Restart named
4. Done.
