" Free and powerful web-based mailing list manager for managing electronic mail discussion and e-newsletter lists. "
- From Mailman Development Team
Mailman is free software for managing electronic mail discussion and e-newsletter lists much like Majordomo and Smartmail. Unlike most similar products, Mailman gives each mailing list a web page, and allows users to subscribe, unsubscribe, etc. over the web.
Mailman is integrated with the web, making it easy for users to manage their accounts and for list owners to administer their lists.
Mailman supports built-in archiving, automatic bounce processing, content filtering, digest delivery, spam filters, and more.
