This is not how PowerDNS was designed, and shows you have probably made an
operating error:

You've made your server authoritative for the root zone, in which case it
has all the right to hand out an NXDOMAIN, as it feels sure there is no and
won't be a record for the right hand side of your CNAME.

I suggest you investigate where this . record comes from.

Good luck!
