Mailman

Mailman is an open source program for managing electronic mail discussion lists and e-newsletter lists. It is intended for people or groups that need to organize email-based discussions, distribute an email newsletter, or manage lists used for both purposes. Its role is specifically the management of these mailing lists: discussion lists are used for exchanges conducted through electronic mail, while e-newsletter lists are used to send newsletter content by email. No particular paid product is identified as a direct replacement for Mailman. Its clearest limitation is also the boundary of its stated purpose: Mailman manages electronic mail discussion and e-newsletter lists. The available description does not establish that it handles other communication channels or broader kinds of email work, so it should not be treated as a general-purpose communications platform. For users who only need mailing-list management, however, its purpose is straightforward and narrowly defined.
