### Mailman, the GNU Mailing List Manager

Mailman is free software for managing electronic mail discussion and e-newsletter lists. 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. See the features page for details.

Mailman is free software, distributed under the GNU General Public License. Mailman is written in the Python programming language, with a little bit of C code for security.

The name of this software is spelled Mailman with a capital leading M and a lowercase second m. It is incorrect to spell it "MailMan" (i.e. you should not use StudlyCaps).

### Current Version

Version 2.1, (released on 30-Dec-2002) is the current released version of Mailman, in production at many sites.
