+Mailbox sharing with symlinks
+=============================
+
+It's possible to share mailboxes simply by symlinking them among user's private
+mailboxes. See <SharedMailboxes.Permissions.txt> for issues related to
+filesystem permissions.
+
+Maildir
+-------
+
+---%<-------------------------------------------------------------------------
+ln -s /home/user2/Maildir/.Work /home/user1/Maildir/.shared.user2
+ln -s /home/user3/Maildir/.Work /home/user1/Maildir/.shared.user3
+---%<-------------------------------------------------------------------------
+
+Now user1 has a "shared" directory containing "user2" and "user3" child
+mailboxes, which point to those users' "Work" mailbox.
+
+With Maildir++ layout it's not possible to automatically share "mailbox and its
+children". You'll need to symlink each mailbox separately. With v1.1+ you could
+do this by using "fs" layout for mailboxes (requires converting existing
+maildirs from Maildir++).
+
+mbox
+----
+
+Doing the same as in the above Maildir example:
+
+---%<-------------------------------------------------------------------------
+mkdir /home/user1/mail/shared
+ln -s /home/user2/mail/Work /home/user1/mail/shared/user2
+ln -s /home/user3/mail/Work /home/user1/mail/shared/user3
+---%<-------------------------------------------------------------------------
+
+One additional problem with mbox format is the creation of dotlock files. The
+dotlocks would be created under user1's directory, which makes them useless.
+Make sure the locking works properly with only fcntl or flock locking (See
+<MboxLocking.txt>) and just disable dotlocks. Alternatively instead of
+symlinking an mbox file, put the shared mailboxes inside a directory and
+symlink the entire directory.
