Hello again group,
 I've solved the problem.
 The master is running latest powerdns 2.9.21.
 The reason it won't send notify to the slave is that
 I have my own php class that manages the database,
 I didn't know the purpose ot 'Notified serial' field in the domains table,
 I supposed that it should be identical as the serial in SOA record,
 so I updated it everytime I updated the soa.
 it appeard that notified serial is _the last serial sent to the slaves_!
 so if anyone's implementing it's own SOA SERIAL MUST BE UPDATED ONLY.
 NOTIFIED SERIAL is being updated by the powerdns and shows the last
 serial sent to the slaves.
 so when mu values of SOA and notified were both the same.... well...
 slaves never got notified

 thanks to everyone for the help,
 hope we see the new notify protocol that will delete domains from the
 I'm very happy with the powerdns, keep doing good job guys! :)
