Hi again :)
Definitely the problem seems to be namespace related.
i applied the modifications to the dovecot.conf file as you suggested 
but now i'm experiencing duplicated folders.

-----------------
b list "" *
* LIST (\HasNoChildren) "/" "Trash"
* LIST (\HasChildren) "/" "INBOX"
* LIST (\HasNoChildren) "/" "INBOX/Trash"
* LIST (\Noselect \HasChildren) "/" "shared/cattivo at ciccio.it"
* LIST (\HasNoChildren) "/" "shared/cattivo at ciccio.it/bumbum"
-----------------

the dovecot.conf namespace section is as follow:

-----------------
namespace private {
        separator = /
        prefix =
        subscriptions = yes

}

namespace private {
     separator = /
     prefix = INBOX/
     inbox = yes
     hidden = yes
}

namespace shared {
  separator = /
  prefix = shared/%%u/
  location = 
maildir:/var/utenti/%d/%%n/Maildir:INDEX=/var/utenti/%d/%n/Maildir/shared/%%u
  subscriptions = no
  list = children
}

-----------------

again... thank you very much for the help :)
