Sieve Email Filtering: Imap4flags Extension
RFC 5232, “Sieve Email Filtering: Imap4flags Extension”, is a Proposed Standard document published in January 2008 by A. Melnikov. The canonical text is published by the RFC Editor.
Abstract
Recent discussions have shown that it is desirable to set different IMAP (RFC 3501) flags on message delivery. This can be done, for example, by a Sieve interpreter that works as a part of a Mail Delivery Agent.
This document describes an extension to the Sieve mail filtering language for setting IMAP flags. The extension allows setting of both IMAP system flags and 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.
