In regard to djbdns, I believe that that's answered at:

http://cr.yp.to/djbdns/dnscache.html

where it says:

dnscache does not cache (or pass along) records outside the
server's bailiwick; those records could be poisoned. Records for
foo.dom, for example, are accepted only from the root servers,
the dom servers, and the foo.dom servers.

Speaking for myself, I never expected anything different. In my
experience, when security information is restricted, the people who
have it aren't particularly concerned about getting it to the people
who don't. More than a year and a half ago, when I saw ISC's message
indicating that security information about BIND would be withheld
from the public, I removed BIND from all my systems and installed
djbdns.

Particularly ironic in light of ISC's apparent delay in releasing
patches is this from the BIND Member Forum FAQ:

Q: So the bind-members Forum programme does not restrict or delay any 
   access to which the industry has become accustomed?
A: Right.
