[Dovecot] v1.2: can't access other users shared INBOX

[Sascha Wilde]

Hi *,

Before going back to the details in this discussion I want to point out
that the whole thing turned out to be really relevant with existing
clients:  The Horde based Kolab WebClient expects the behavior as shown
by Cyrus IMAP and fails to show "user/A at example.com/INBOX" as dovecot
currently lists A's INBOX.

While this might be considered a bug in Horde it shows that existing
clients actually highly depend on the behavior as seen in Cyrus IMAP.

I'm talking about 1 vs 2 if you will.  ;-)
I expected "user/A at example.com" to be A's INBOX, while BH pointed out,
that with the current implementation it is more likely that
"user/A at example.com/INBOX" actually refers to A's INBOX.

Yes, cyrus does that.

No, it doesn't as, the INBOX of A is referred to as
"user/A at example.com", so "A at example.com/INBOX" would actually be an
folder named "INBOX".  Which would be displayed as "INBOX/INBOX" from
A's point of view:

User A:           when shared to User B maps to:
INBOX             user/A at example.com
INBOX/foo         user/A at example.com/foo
INBOX/foo/bar     user/A at example.com/foo/bar
