wrong. The notify is usually sent to all servers which have NS record,
except the one in SOA. So, put the name of real master into SOA (even if
it's not accessible from the net). don't put name of any slave to SOA.
You can of course override these settings with "notify (yes|no|explicit)"
and also-notify settings in BIND config.
