dovecot - Apr 2015 - cant see all users - need to create symlink between mailboxes [request for help]

Hi,
I need to create a symlink to share mailboxes.
I tried to check at : cd /var/mail/ but I cant see all the mailboxes.
Could someone advise how to do this?

I am trying to achieve as showing in tutorial here:-
http://wiki.dovecot.org/SharedMailboxes/Symlinks

Below is the details of my dovecot.conf
Appreciate if anyone can help.

Hi,
Its okay now. I decided to use ACL.
Apparently the "Sent" mailbox cannot be viewed by dave. Any idea why?

When I do GETACL for Sent, the message I get is shown below:-

* ACL "Sent" "dave at mydomain.net" ilr "help at
mydomain.net" lrwstipekxacd
