I have just sent the details of strace and dig, in a separate mail
Frankly I do not know how to read the results.
dnstracer -v my-server.mydomain.com fails with, return code 3 (Name error)
dnstracer -v -q cname my-server.mydomain.com succeeds, returns Resource
It looks like my resolver only checks the local dns for A records.
