 Abstract
 
    RFC 6154 created an IMAP Special-Use LIST extension and defined an
    initial set of attributes.  This document defines a new attribute,
    "\Important", and establishes a new IANA registry for IMAP folder
    attributes, registering the attributes defined in RFCs 3348, 3501,
    and 6154.  This document also defines a new IMAP keyword,
    "$Important", and registers it in the registry defined in RFC 5788.

    Internet-Drafts are working documents of the Internet Engineering
    Task Force (IETF).  Note that other groups may also distribute
    working documents as Internet-Drafts.  The list of current Internet-
    Drafts is at http://datatracker.ietf.org/drafts/current/.
 
    Internet-Drafts are draft documents valid for a maximum of six months
    and may be updated, replaced, or obsoleted by other documents at any
    time.  It is inappropriate to use Internet-Drafts as reference
    material or to cite them other than as "work in progress."

    strategic starting point.  If the algorithm by which messages are
    determined to be important is well known, still more information is
    exposed -- perhaps, for example, there is an implication that the
    senders of these messages are particularly significant to the mailbox
    owner, and perhaps that is information that should not be made
    public.
 
    As noted in RFC 6154, it is wise to protect the IMAP channel from
    passive eavesdropping, and to defend against unauthorized discernment

 6.  IANA Considerations
 
    This document contains 3 actions for IANA, specified in the sections
    below:
 
    1.  Registration of the "$Important" keyword.
 
    2.  Creation of a new "IMAP Mailbox Name Attributes" registry.
