You can't. If BIND is not configured for the name, or the zone which contains the name, then the only way it can get it is by recursing,
which you say below you do not want to do.

I have a couple of kludgey ideas:

1) Have a script periodically (less than TTL) query the canonical name from an address which is allowed to recurse (e.g. loopback). That
way, the record is always in the cache and will be returned since the server doesn't have to recurse for it.

2) Set up a zone for just the canonical name. This requires the creation of some sort of synchronization mechanism, in case the canonical
name ever changes.
