Having heard about recursion, is there a way of getting BIND to make recursive DNS requests to the A.B.C.D and E.F.G.H DNS servers?
forwarding causes BIND to send recursive DNS requests, in both domain and server config. But note that you should only use it when you don't have direct connectivity to the destination (or the internet at all). If you want to use non-recursive queries, configure domain as static-stub.

It ocasionally re-tries slower server, if the situation did not change. That should result to fastest resolution. This should be the best for you. Many people recommend doing recursion directly instead of using forwarders. Especially for mail servers with anti-spam measures, where your forwarders may be ignored by some blacklists, because they send too much queries.
