I can see why it doesn't help as well since this option is intended to
allow Internet addresses to be overridden.

What I am querying is at what steps the recursion occurs.

If I query my recursor enabled pdns server, which is authoritative on
a domain but which has only CNAME records, for one of those records
then surely it will:

- look up the result for the query

- find that it's a CNAME and recurse on the value of the CNAME

eg: I look up for www.X.com which is CNAMEd to realserver.Y.com and
the server does this:

  lookup www.X.com results in CNAME realserver.Y.com

  recurse for realserver.Y.com

  respond with the result

but this is not what powerdns seems to do.

Help! Please?
