reverse delegation from Telco

Everything is working as it should. Your servers (I'm guessing they're your servers) are responding authoritatively for the rewritten PTR record name. You're seeing a non-authoritative response because you're asking for the canonical PTR record name, for which your server is not authoritative (Telus' servers are). But the final part of the answer, from your zone '', is authoritative.

I'm making the assumption that and are yours.
