Sieve Email Filtering: Spamtest and Virustest Extensions
RFC 5235, “Sieve Email Filtering: Spamtest and Virustest Extensions”, is a Proposed Standard document published in January 2008 by C. Daboo. It obsoletes RFC 3685. The canonical text is published by the RFC Editor.
Abstract
The Sieve email filtering language "spamtest", "spamtestplus", 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 proper input to the tests. [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.
