Does the zimbra IMAP server support admin access to user accounts? I know about AUTH PLAIN, this is something else.

For example:

$ telnet imap.myserver.com 143
* OK imap.myserver.com Zimbra IMAP4rev1 service ready
1 login admin_user password
2 select "some_other_user.INBOX.Sent"

If this is possible, what's the syntax for the folder path from root?

TIA
