rbldnsd is not a general purpose dns server.  It is specially designed 
to only serve up RBL databases it knows about. It can not do recursive 
queries(in other words, it can not ask other name servers questions).

Everything you mention can be done with BIND or any other general 
purpose name server.

As far as #2, that parameter should be controlled by the other end. 
They should specify the TTL for how long to cache a record.
