RFC 5228: Sieve: An Email Filtering Language

Still current, but amended. Parts of this document are changed or extended by RFC 5229, RFC 5429, RFC 6785, RFC 9042. Read both.

In plain English — editorial summary, not part of the RFC

This document describes a language for filtering email messages at time of final delivery. It is designed to be implementable on either a mail client or mail server. It is meant to be extensible, simple, and independent of access protocol, mail architecture, and operating system. It is suitable for running on a mail server where users may not be allowed to execute arbitrary programs, such as on black box Internet Message Access Protocol (IMAP) servers, as the base language has no variables, loops, or ability to shell out to external programs.
