Sieve Email Filtering: Variables Extension
RFC 5229, “Sieve Email Filtering: Variables Extension”, is a Proposed Standard document published in January 2008 by K. Homme. It updates RFC 5228. It has since been updated by RFC 5173. The canonical text is published by the RFC Editor.
Abstract
In advanced mail filtering rule sets, it is useful to keep state or configuration details across rules. This document updates the Sieve filtering language (RFC 5228) with an extension to support variables. The extension changes the interpretation of strings, adds an action to store data in variables, and supplies a new test so that the value of a string can be examined. [STANDARDS-TRACK]
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.
