Forwarding is a modification of recursion -- it tells the server 
"Instead of querying the servers in the NS records, query these specific 
servers." But if you're not recursing (either because recursion is 
disabled, or because the client didn't request it), you won't forward.

Authoritative servers usually don't get requests with the Recursion 
Desired flag -- external caching servers usually do iterative queries. I 
don't understand why this is a problem for you, though. You said you're 
delegating to an external nameserver, so when you return the referral 
they should be able to go there by themselves.
