This document defines a new attribute, "\textbackslash{}Important", and establishes a new IANA registry for IMAP folder attributes, which include the attributes defined in RFCs 5258, 3501, and 6154. This document also defines a new IMAP keyword, "\$Important", and registers it in the registry defined in RFC 5788.},
