or dump zone from rbldnsd to bind.zone, the bind zone can be in sqlite

This is completely irelevant, since DNSBL/DNSWL servers will get any kind of
queries from the OP which is what causes the trouble.
The solution at OPs nameserver is to turn QNAME minimization off completely,
unless it's possible only turn it for some domains (it's not now).

All it would take to fix it is returning NOERROR instead of NXDOMAIN
when a record does not exist. Perhaps one line change.
from later discussion on this list, there's already issue open and patch
waiting:
