It's not uncommon to configure BIND to forward requests for a DNSBL
zone to another local listener, so that one can take advantage of both
BIND local zones and rbldnsd local zones.

See http://www.njabl.org/rsync.html for an example -- the BIND config
of which looks like:

zone "dnsbl.njabl.org" IN {
        type forward;
        forward first;
        forwarders {
                127.0.0.1 port 530;
        };
};
