[Unbound-users] Disable scrubber for certain host/domain names

Hello all,

I hope this question hasn't been answered already (made a search before).

I am using Unbound with Postfix to query RBL servers. A check for IP
x.y.w.z against a certain RBL server (say rbl.example.com) would send
a DNS query to resolve z.w.y.x.rbl.example.com. The answer is a
127.0.0.x address.

Due to Unbound's scrubber, though, this answer is discarded (with a
warning "debug: sanitize: removing public name with private address")
which of course makes sense in other circumstances, but not in this
one.

I was wondering if there's a way, or a configuration command, to turn
off this behavior for certain host/domain names. This will make
running Unbound with RBL quite possible.

Any help on how to resolve this with the current version is greatly
appreciated. Thanks in advance.
