Hi, I've one installation where they have ony 3 "real" account (i.e. info@theirdomain.it) that fetche e-mail with pop3, and want to create i.e. other 10 accounts in zimbra to be able to use Calendar and exchange mails internally in the office.
They want to prevent the other accounts to be able to send mail outside zimbra (could be easily done by accident and without error, just and answer would never come back )
Is it possible and how? I've found something in wiki but looks about letting only some users send to a particular domain, that is not what I need.
(Zimbra 6.0beta2 OS)
