Maybe the problem is that English isn't your native language, but what do
you mean by "behave recursively whenever the query comes from the zone it
is authoritative"?  If a server is authoritative for a zone, it will never
recurse for data in that zone, since it knows the answer (that's what
"authoritative" means).

Do you mean that it should recurse if the query comes from a client machine
whose name is in a zone that it's authoritative for?  BIND doesn't have
such a feature.  You can configure the allow-recursion option to specify
who can perform recursive queries by IP address, but not by domain name.
