RFC7888 - IMAP4 Non-synchronizing Literals

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.

RFC7889 - The IMAP APPENDLIMIT Extension

This document defines an extension to the IMAP service whereby a server can inform the client about maximum message upload sizes, allowing the client to avoid sending APPEND commands that will fail because the messages are too large.
