About Sympa

Sympa is a mailing list manager designed for handling large-scale email discussion lists, newsletters, and announcement systems. It supports list creation through a web interface, automated bounce management, and integration with authentication systems like LDAP and SSO. Lists can be public, private, or moderated, and the software includes archiving, digest modes, and customizable templates.

Built in Perl with a modular architecture, Sympa works on Linux and Unix systems, and integrates with major MTAs like Postfix, Sendmail, and Exim. It uses a SQL database backend (MySQL or PostgreSQL) and provides a REST API for automation. The project is maintained by the Sympa Community, with contributions from organizations like RENATER and the French Ministry of Education.

It is especially suited for academic institutions, research organizations, and enterprises that need reliable list management without licensing costs. Sympa is released under the GPLv2 license, with a stable release cycle and active security updates.
