The Internet Message Access Protocol (RFC 3501) contains the
"literal" syntactic construct for communicating strings. When
sending a literal from client to server, IMAP requires the client to
wait for the server to send a command continuation request between
sending the octet count and the string data. This document specifies
an alternate form of literal that does not require this network round
trip.
This document specifies 2 IMAP extensions: LITERAL+ and LITERAL-.
LITERAL+ allows the alternate form of literals in all IMAP commands.
LITERAL- is the same as LITERAL+, but it disallows the alternate form
of literals unless they are 4096 bytes or less.
This document obsoletes RFC 2088.
This document is a product of the IMAP APPEND Extensions Working Group of the IETF.
This is now a Proposed Standard.
