Collected Extensions to IMAP4 ABNF

Overview

RFC 4466, “Collected Extensions to IMAP4 ABNF”, is a Proposed Standard document published in April 2006 by A. Melnikov, C. Daboo. It updates RFC 2088, RFC 2342, RFC 3501, RFC 3502, RFC 3516. It has since been updated by RFC 6237, RFC 7377. The canonical text is published by the RFC Editor.

Abstract

Over the years, many documents from IMAPEXT and LEMONADE working groups, as well as many individual documents, have added syntactic extensions to many base IMAP commands described in RFC 3501. For ease of reference, this document collects most of such ABNF changes in one place.

This document also suggests a set of standard patterns for adding options and extensions to several existing IMAP commands defined in RFC 3501. The patterns provide for compatibility between existing and future extensions.

This document updates ABNF in RFCs 2088, 2342, 3501, 3502, and 3516. It also includes part of the errata to RFC 3501. This document doesn't specify any semantic changes to the listed RFCs. [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
