[Pdns-users] PowerDNS and CNAMEs

Hey gurus.

I have a strange issue with CNAME records that I hope you can help me
solve, or at least clarify why it is like this.

I have a CNAME, service.my-domain.com, pointing to host.other-domain.com.
Now, if the A record for host.other-domain.com is managed by my PowerDNS,
this works fine.
If, on the other hand, host.other-domain.com is hosted by third party, the
recursor functionality of PowerDNS seems strange. In stead of trying to
resolve host.other-domain.com on the upstream server, it tries to resolve
the original request, i.e. service.my-domain.com.

Is this expected behaviour? Or have I botched my configuration somehow?
