Well upgrade to BIND 9.2 to get the name of the zone.
Note BIND 9.3 will also report the client that sent the
notify, but you need to run a snapshot. Turning on
debugging will supply this with BIND 9.2.
Modern tcpdump also knows about notify so you could use
this to find the client as well by coralating timestamps.

A server set you a notify request for a zone you don't
serve.
