I'm using Zimbra Open Source to manage multi-domain account, and I have added some user to the "admin" group so they can enter to the Admin Console (7071 port).

My big problem is that this other administrator user CAN view all mail inbox and all the messages for that users. I need that only the other user administrator can add/modify/delete email account but not view client private messages.

How can I disable the "View Mail" Option from the Admin Console (7071)?

Thanks for your time.
