[rbldnsd] a "bind + rbldns on same machine HOW-TO"?

[rbldns at 2005.ebuzz.de]

Hi all,

Is there a "bind + rbldns on same machine HOW-TO"?

I read this thread:
http://www.corpit.ru/pipermail/rbldnsd/2005q1/000310.html
and
http://www.tqmcube.com/rbldnsd.htm

But it didn't solve my problems.

I want a setup that looks like:

=> "bl.example.com" is "parent" zone used for a webpage.
=> "helofaker.bl.example.com" and "ix-list.bl.example.com"
are rbldns served zones.
=> my rblzones are not restricted to localhost use.
=> bind is authoritative for example.com

What exact changes do I need make to named.conf
Do I have to serve my rblzone with $NS?

Thanks for your answers.
Lars
