Sieve Email Filtering: Ihave Extension

Overview

RFC 5463, “Sieve Email Filtering: Ihave Extension”, is a Proposed Standard document published in March 2009 by N. Freed. The canonical text is published by the RFC Editor.

Abstract

This document describes the "ihave" extension to the Sieve email filtering language. The "ihave" extension provides a means to write scripts that can take advantage of optional Sieve features but can still run when those optional features are not available. The extension also defines a new error control command intended to be used to report situations where no combination of available extensions satisfies the needs of the script. [STANDARDS-TRACK]
