HI All,

I am able to block some users to send mails to certain doamin,, using

Restrict users to certain domain - Zimbra :: Wiki

but my problem is we have to add each and every user to the file restricted_senders .. so is there any option to block Groups in zimbra so that once user is added to group it will automatically block the users to send mails,,

any one have idea please help me,, thanks in advance....
