Internet Engineering Task Force (IETF) B. Leiba Request for Comments: 6785 Huawei Technologies Updates: 5228 November 2012 Category: Standards Track ISSN: 2070-1721 Support for Internet Message Access Protocol (IMAP) Events in Sieve Abstract Sieve defines an email filtering language that can, in principle, plug into any point in the processing of an email message. As defined in the base specification, it plugs into mail delivery. This document defines how Sieve can plug into points in IMAP where messages are created or changed, adding the option of user-defined or installation-defined filtering (or, with Sieve extensions, features such as notifications). Because this requires future Sieve extensions to specify their interactions with this one, this document updates the base Sieve specification, RFC 5228. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
