GNU Mailman is a computer software application from the GNU Project for managing electronic mailing lists.^[4]^[5] Mailman is coded primarily in Python and currently maintained by Abhilash Raj.^[1] Mailman is free software, licensed under the GNU General Public License.^[5]

History

A very early version of Mailman was written by John Viega while a graduate student, who then lost his copy of the source in a hard drive crash sometime around 1998.^[6] Ken Manheimer at CNRI, who was looking for a replacement for Majordomo, then took over development. When Manheimer left CNRI, Barry Warsaw took over. Mailman 3—the first major new version in over a decade—was released in April 2015.^[7]

Features

Mailman runs on most Unix-like systems, including Linux. Since Mailman 3.0 it has required python-3.4 or newer.^[8] It works with Unix-style mail servers such as Exim, Postfix, Sendmail and qmail. Features include:

A customizable publicly-accessible web page for each maillist.
Web application for list administration, archiving of messages, spam filtering, etc. Separate interfaces are available for users (for self-administration), moderators (to accept/reject list posts), and administrators.
Support for multiple administrators and moderators for each list.
Per-list privacy features, such as closed-subscriptions, private archives, private membership rosters, and sender-based posting rules.
Integrated bounce detection and automatic handling of bouncing addresses.
Integrated spam filters
Majordomo-style email based commands.
Support for virtual domains.
List archiving. The default archiver provided with Mailman 2 is Pipermail,^[9] although other archivers can be used instead. The archiver for Mailman 3 is HyperKitty.^[10]
