Sieve Email Filtering: Delivering to Special-Use Mailboxes

Overview

RFC 8579, “Sieve Email Filtering: Delivering to Special-Use Mailboxes”, is a Proposed Standard document published in May 2019 by S. Bosch. The canonical text is published by the RFC Editor.

Abstract

The SPECIAL-USE capability of the IMAP protocol (RFC 6154) allows clients to identify special-use mailboxes, e.g., where draft or sent messages should be put. This simplifies client configuration. In contrast, the Sieve mail filtering language (RFC 5228) currently has no such capability. This memo defines a Sieve extension that fills this gap: it adds a test for checking whether a special-use attribute is assigned for a particular mailbox or any mailbox, and it adds the ability to file messages into a mailbox identified solely by a special-use attribute.

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.
