Thanks for your reply but is there any other way? cause in this way I have to add all currend and new users in to protected_recipients file, I dont want to do such long process. My concern is by default it should block all domain and allow certain domain which I want.

Thanks....

Sorry do not agree ... A MTA should receive email from all domains, that is its purpose, and reject based on selective criteria. You could write a script to dump all your configured users using zmprov and hold a list of blocked domains. Merge the two and you would then have the complete list.
