Are you sure that this is an explicit support in the mail server?

Here's what Mark Crispin (the author of both UW-imapd and c-client)
wrote recently:

|  	{imap.example.com/authuser=fred/user=joe}INBOX

| joe using user fred's password, and then open joe's INBOX.  This assumes
| that user fred is in group mailadm on the imap.example.com.

So can you do this trick manually? authenticate as one user and read
another user's mailbox?

Here's an example with root and pre-authentication. I figure that some
tricks with pam and such will get you further:

root at server# MAIL=maildir:/home/tzafrir/Maildir /usr/lib/dovecot/imap
* PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND
* UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE]
* Logged in as root
1 list "" "*"
* LIST (\HasNoChildren) "." INBOX
1 OK List completed.
2 select INBOX
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)]
* Flags permitted.
* 0 EXISTS
* 0 RECENT
* OK [UIDVALIDITY 1161851409] UIDs valid
* OK [UIDNEXT 1] Predicted next UID
2 OK [READ-WRITE] Select completed.
* logout
* BYE Logging out
* OK Logout completed.

This is dovecot 0.99.14 on Debian Sarge. Note that I actually don't use
that imap mailbox normally.
