1. Powerful, web-based mailing list manager The GNU Mailing List Manager, which manages email discussion 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. Even the list manager can administer his or her list entirely from the web. Mailman also integrates most things people want to do with mailing lists, including archiving, mail <-> news gateways, and so on. It has all of the features you expect from such a product, plus integrated support for the web (including web based archiving), automated bounce handling and integrated spam prevention.
