About mlmmj

mlmmj is a mailing list manager written in C that focuses on being lightweight and efficient. It handles list subscriptions, message distribution, and bounce processing without relying on a database. The software uses a modular design where each list is stored as a directory of text files, making it easy to administer and script.

It supports standard mailing list features like moderation, digests, subject prefixing, and custom headers. You can integrate it with any Mail Transfer Agent that accepts pipe commands, including Postfix, Sendmail, and Exim. The project uses a simple file-based backend, which means no separate database daemon is needed, reducing memory and CPU overhead on your server.

This tool is ideal for system administrators who need a no-fuss mailing list solution on a Unix-based mail server. It is released under the GNU General Public License version 2, so it is open source and free to use. The project was originally developed by Mads Martin Jørgensen and has a small but dedicated community maintaining it.
