SIEVE Email Filtering: Spamtest and VirusTest Extensions
RFC 3685, “SIEVE Email Filtering: Spamtest and VirusTest Extensions”, is a Proposed Standard document published in February 2004 by C. Daboo. It has been obsoleted by RFC 5235 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
The SIEVE mail filtering language "spamtest" and "virustest" extensions permit users to use simple, portable commands for spam and virus tests on email messages. Each extension provides a new test using matches against numeric 'scores'. It is the responsibility of the underlying SIEVE implementation to do the actual checks that result in values returned by the tests. [PROPOSED STANDARD]
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.
