The Internet Email to Support Diverse Service Environments Profile
RFC 5550, “The Internet Email to Support Diverse Service Environments Profile”, is a Proposed Standard document published in August 2009 by D. Cridland, A. Melnikov, S. Maes. It updates RFC 4467, RFC 4469. It obsoletes RFC 4550. The canonical text is published by the RFC Editor.
Abstract
This document describes a profile (a set of required extensions, restrictions, and usage modes), dubbed Lemonade, of the IMAP, mail submission, and Sieve 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 Lemonade Profile relies upon several extensions to IMAP, Sieve, and Mail Submission protocols. The document also defines a new IMAP extension and registers several new IMAP keywords. [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.
