1.  Introduction

   IMAP [RFC3501] only allows body parts or message sizes which are 32
   bit.  This document introduces an IMAP extension that allows for
   message and body part sizes to be 63 bit.

   The client wishing to use this extension MUST issue ENABLE 64BIT.
   Refer [RFC5161] for the usage of ENABLE command.

2.  Requirements Notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   In examples, "C:" and "S:" indicate lines sent by the client and
   server respectively.  If a single "C:" or "S:" label applies to
   multiple lines, then the line breaks between those lines are for
   editorial clarity only and are not part of the actual protocol
   exchange.
