The Internet Message Access Protocol Version 4rev2 (IMAP4rev2) allows
a client to access and manipulate electronic mail messages on a
server.  IMAP4rev2 permits manipulation of mailboxes (remote message
folders) in a way that is functionally equivalent to local folders. 
IMAP4rev2 also provides the capability for an offline client to
resynchronize with the server. 

IMAP4rev2 includes operations for creating, deleting, and renaming
mailboxes; checking for new messages; removing messages permanently;
setting and clearing flags; parsing per RFCs 5322, 2045, and 2231;
searching; and selective fetching of message attributes, texts, and
portions thereof.  Messages in IMAP4rev2 are accessed by the use of
numbers. These numbers are either message sequence numbers or unique

IMAP4rev2 does not specify a means of posting mail; this function is
handled by a mail submission protocol such as the one specified in
RFC 6409.

This document is a product of the Email mailstore and eXtensions To Revise or Amend Working Group of the IETF.

This is now a Proposed Standard.
