mailman 1:2.1.20-1ubuntu0.3 (amd64 binary) in ubuntu xenial

 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.
