Collected Extensions to IMAP4 ABNF
Alexander Viktorovich Melnikov, Cyrus Daboo · 2006
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.
