Why do you want to do this? Forging DNS records of foreign domains has
always been a nasty behaviour. If you want a machine that can be used
as a DNS server that forwards all queries to another machine, you are
looking for a so called stub-resolver. BIND can be configured for that
case. You need to enter the target servers as forwarders.
That will cause BIND to forward all queries with recursion desired flag
and cache them.
