This is correct operation.  Recursive/iterative servers talking to
it do not need your server to resolve the target of the cname.  They
will go ask the nameservers for the target of the cname themselves
then combine the two answers and return that to the caller.

Stub resolvers need to talk to a recursive server so it can do this
work on their behalf.

No.
