The Mailbox Update Distributed Mailbox Database Protocol
RFC 3656, “The Mailbox Update Distributed Mailbox Database Protocol”, is an Experimental document published in December 2003 by R. Siemborski. It has since been updated by RFC 8996. The canonical text is published by the RFC Editor.
Abstract
As the demand for high-performance mail delivery agents increases, it becomes apparent that single-machine solutions are inadequate to the task, both because of capacity limits and that the failure of the single machine means a loss of mail delivery for all users. It is preferable to allow many machines to share the responsibility of mail delivery. The Mailbox Update (MUPDATE) protocol allows a group of Internet Message Access Protocol (IMAP) or Post Office Protocol - Version 3 (POP3) servers to function with a unified mailbox namespace. This document is intended to serve as a reference guide to that protocol.
