Aha, perhaps I know what it means.
Have you configured SOA in the zone you're using?  Without SOA configured,
rbldnsd can't answer with NXDOMAIN, so it just REFUSEs the query, and such
a reply gets translated into SERVFAIL by your forwarder.

Well... it's interesting.  Lemme take a more detailed look at this...
