1.  Introduction

   IMAP clients typically fetch the set of rights granted on mailboxes
   so they can expose the allowed functionality to the logged-in user.
   In order to do that, the client is forced to issue a LIST or LSUB
   command to list all available mailboxes, followed by a MYRIGHTS
   command for each mailbox found.  This document defines an extension
   to the to IMAP LIST command that allows the client to request the set
   of rights that the logged-in user has been granted on mailboxes,
   along with other information typically returned by the LIST command.
