I guess I'm missing something.
I'm using a dns server: mail.mydomain.com (mydomain is my real domain) and the
"name" parameter is
"google.com" and QType is mx (15). No matter what I do, I keep getting an empty
result. Debugging shows me
that the received QType (RType variable) is 6 (instead of 15) so the result is
empty. What am I missing?
