Firstly, please don't hide domains: see

Secondly, which of those domains is your server authoritative for?

PowerDNS will not attempt to follow CNAME records.  General recursion 
was removed in Authoritative Server 4.1.  (It will send queries for 
ALIAS records, but only if you've configured it with a recursor to use).
