              Sieve Email Filtering: delivery by mailboxid
                  draft-ietf-extra-sieve-mailboxid-09

Abstract

   The OBJECTID capability of the IMAP protocol (RFC8474) allows clients
   to identify mailboxes by a unique identifier which survives rename.

   This document extends the Sieve mail filtering language (RFC5228) to
   allow using that same unique identifier as a target for fileinto
   rules, and for testing the existance of mailboxes.

1.  Introduction

   [RFC5228] Sieve rules are sometimes created using graphical
   interfaces which allow users to select the mailbox to be used as a
   target for a rule.

   If that mailbox is renamed, the client may also update its internal
   representation of the rule and update the sieve script to match,
   however this is a multi-step process and subject to partial failures.
