Together with a external developer we are investigating the possibility to create a user in Zimbra with privileges to read *other* users inboxes.


1) One server/application authenticate to the Zimbra server with a "special-privileged-read-user".

2) After this authentication this user can read any other given users inbox to show "You have X new mail" and maybe subject on the X last mails for that user.

My question is if this is possible in a simple way without to much special "hacks" on the Zimbra side?

Note: The external application do not have access to the users password, only the username.
