libsieve is a C library. libsieve has no bugs and it has low support. However libsieve has 1 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub.

This code is a standalone library providing an interpreter for RFC 3028 Sieve and various extensions. It is based upon code distributed with the Cyrus Mail Server prior to CMU's switch to a more restrictive license. The libSieve API attempts to be easy to use and extensible, and replaces the more rigid API in the Cyrus Sieve implementation. For questions, comments, and bug reports regarding this library, please contact Aaron Stone aaron@serendipity.cx directly. There are no mailing lists. The documents listed below coincide with those features currently implemented in libSieve. Both as these documents progress through the standardization process and as libSieve itself matures, additional extensions and later revisions of them will be implemented.
