Internet Email to Support Diverse Service Environments Profile
RFC 4550, “Internet Email to Support Diverse Service Environments Profile”, is a Proposed Standard document published in June 2006 by S. Maes, A. Melnikov. It has been obsoleted by RFC 5550 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a profile (a set of required extensions, restrictions, and usage modes) of the IMAP and mail submission protocols. This profile allows clients (especially those that are constrained in memory, bandwidth, processing power, or other areas) to efficiently use IMAP and Submission to access and submit mail. This includes the ability to forward received mail without needing to download and upload the mail, to optimize submission, and to efficiently resynchronize in case of loss of connectivity with the server.
The Internet Email to Support Diverse Service Environments (Lemonade) profile relies upon extensions to IMAP and Mail Submission protocols; specifically, the URLAUTH and CATENATE IMAP protocol (RFC 3501) extensions and the BURL extension to the SUBMIT protocol (RFC 4409). [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.
