Mailman is coded primarily in [[Python (programming language)|Python]] and currently maintained by Abhilash Raj.<ref name="developer-announcement-2017">{{Cite mailing list|url=https://mail.python.org/pipermail/mailman-announce/2017-November/000232.html|title=Time Stand Still|language=en|access-date=5 September 2018|first1=Barry|last1=Warsaw|date=23 November 2017|mailing-list=Mailman-Announce}}</ref> Mailman is [[free software]], licensed under the [[GNU General Public License]].<ref name="http://www.gnu.org"/>

== 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.<ref name="http://myriadicity.net">{{cite web| url = http://myriadicity.net/Sundry/MyMailmanRole | title =MyMailmanRole&nbsp;— Myriadicity Dot| access-date = 2009-02-11 }}</ref> Ken Manheimer at [[Corporation for National Research Initiatives]] (CNRI), who was looking for a replacement for [[Majordomo (software)|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.<ref name="lwn_mm3">{{cite web | url=https://lwn.net/Articles/638090/ | title=Mailman 3.0 to modernize mailing lists | publisher=lwn.net | date=27 March 2015 | access-date=15 October 2015}}</ref>

== Features ==
Mailman runs on most [[Unix]]-like systems, including [[Linux]]. Since Mailman 3.0 it has required [[History of Python#Version 3|Python-3.4]] or newer.<ref name="mm_req">{{cite web |url=http://mailman.readthedocs.org/en/latest/src/mailman/docs/START.html#requirements |title=Getting started with GNU Mailman |publisher=mailman.readthedocs.org |access-date=14 October 2015 |url-status=dead |archive-url=https://web.archive.org/web/20151013205802/http://mailman.readthedocs.org/en/latest/src/mailman/docs/START.html#requirements |archive-date=13 October 2015 }}</ref> It works with Unix-style [[Message transfer agent|mail servers]], such as [[Exim]], [[Postfix (software)|Postfix]], [[Sendmail]] and [[qmail]]. Features include:
* A customizable publicly-accessible [[Web page]] for each [[Mailing list#Electronic mailing list|maillist]].
* [[Web application]] for list administration, archiving of messages, [[email spam|spam]] filtering, etc. Separate interfaces are available for users (for self-administration), [[Internet forum#Moderators|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 (software)|Majordomo]]-style email based commands.
* Support for [[Virtual hosting#Name-based|virtual domains]].
