Remove DNS zone files on Slave DNS

Hello

When I delete zones in Plesk (which is the Master DNS), they are not deleted on the Slave DNS servers. Adding and modifying zones is not a problem, but zone files are not removed on the slave DNS servers when they are removed from the Plesk Master DNS server.

It seems that no 'rndc delzone' is executed when removing a domain.

Any thoughts on this?

Thanks
