  • Language: C

• Sieve-Parser's sieve-parser is a pure-ruby implementation for parsing and manipulate the sieve scripts.
  • Language: Ruby

• JSieve is a Java implementation of the Sieve mail filtering language. It is implemented as a language processor that can be plugged into any internet mail application to add Sieve support. jSieve is a subproject of Apache JAMES.
  • Language: Java

• libSieve implements the Sieve mail sorting language, per RFC 3028. LibSieve was based on the Cyrus Imapd project, but offers a standalone library that other projects can use.
  • Language: C

• libsieve-php implements the Sieve mail sorting language, per RFC 3028 and extensions, for PHP. Currently under development. ManageSieve support is planned.
  • Language: PHP

• Net::Sieve::Script is a Perl interface to parse and write Sieve scripts. Works together with Net::Sieve (below).

• sievelib is a Python implementation of a Sieve parser and a ManageSieve client.
  • Language: Python

• sifter is a Python library for parsing a Sieve script and evaluating it against an email message. Supports the regex extension, with support for other extensions under development.
  • Language: Python

The following projects provide support for ManageSieve; the purpose is to upload and activate a Sieve script to an email service. It is assumed that the actual Sieve script is created by other means (e.g. manually or through a client UI).

• php-sieve-manager is a modern (started in 2022) PHP library for managing the ManageSieve protocol (RFC5228) and generating basic Sieve scripts. Used by Cypht Webmail.
