notify send by Master zones

[Jeff Reasoner]

Notifys are sent by default for all loaded zones. They go only to the
nameservers listed in the zonefile unless overridden with 'also-notify'
statements in the zone clause in named.conf.

Notify behavior is also tunable using several named.conf options
statements.

I'd recommend checking the BIND9 ARM (esp. section 4.1) for a more
extensive explanation.
