Sieve Implementations

This space is intended to be a single-stop listing of all announced available Sieve implementations, or pre-announcements of any work in progress as made by any individual, organization, or company.

Other implementations might be underway for commercial and/or proprietary products by a number of companies. Check the mailing list archives for details, questions, or hints based on the participants' comments.

This page has been split to three different parts:

• Sieve Clients
• Sieve-enabled Servers
• Sieve Libraries, Extensions, APIs

A list of supported extensions by product is available at Fastmail.FM wiki's Sieve Extension Support Matrix.
