This document describes a profile (a set of required extensions,
restrictions, and usage modes), dubbed Lemonade, of the IMAP, mail
submission, and Sieve protocols.  This profile allows clients
(especially those that are constrained in memory, bandwidth,
processing power, or other areas) to efficiently use IMAP and
Submission to access and submit mail.  This includes the ability to
forward received mail without needing to download and upload the
mail, to optimize submission, and to efficiently resynchronize in
case of loss of connectivity with the server.

The Lemonade Profile relies upon several extensions to IMAP, Sieve,
and Mail Submission protocols.  The document also defines a new IMAP
extension and registers several new IMAP keywords.  [STANDARDS TRACK]
