So you can see that my mail server is querying its local DNS resolver,
which is querying the root servers and then working its way down to the
appropriate uribl.com server. In your case your actual IPs will be
different, but the pattern should still hold.
no, it's the "dig" command that does the trace, not the nameserver.
This says nothing about your nameserver configuration, and it can't since
nameserver does not provide that info.
