Overview
RFC 9698, “The JMAPACCESS Extension for IMAP”, is a Proposed Standard document published in January 2025 by A. Gulbrandsen, B. Gondwana. The canonical text is published by the RFC Editor.
Abstract
This document defines an IMAP extension to let clients know that the messages in this IMAP server are also available via the JSON Meta Application Protocol (JMAP), and how. It is intended for clients that want to migrate gradually to JMAP or use JMAP extensions within an IMAP client.
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.
