[MaraDNS list] MaraDNS authoritative and recursive config issue

upstream_servers doesn't work in MaraDNS 2.0; the maradns daemon in
MaraDNS 2.0 *only* returns data from zone files.

When you want to resolve a query which you are not in control of, such
as "maradns.org" or "google.com", Deadwood is the program to use.

Deadwood will only do recursive (or upstream) queries; MaraDNS will
only do authoritative queries.

While I believe complex setups with both root_servers and
upstream_servers are set are possible, they haven't been tested in
Deadwood.  Try using upstream_servers["example.org."] = "127.0.0.1"
instead of root_servers and see if that resolves your issue (since the
server at 127.0.0.1 is MaraDNS 2.0, there is no condition whatsoever
that will result in the reply causing a query loop).

bind_address="0.0.0.0" works if you just want to use every IP your
computer happens to have.

Anyway, you may or may not have found a bug.  I will work with you on
the list to see if the issue is a configuration (or documentation)
issue or an honest-to-God bug in Deadwood.  If we do determine it is a
bug, the next day I have scheduled for working on Deadwood is
September 5; I already have an issue with upstream_servers that
returns a SERVER FAIL to fix. If this issue is important enough that
it needs to be fixed more quickly, I'm willing to talk if there's
money on the table.
