Overview
Majordomo is a mailing list manager (MLM) developed by Brent Chapman. It is written in Perl and works in conjunction with sendmail on UNIX and related operating systems. The name majordomo is derived from the Latin "major domus" meaning "master of the house"; in English, the word is used to refer to a large household's chief servant.
The current version of Majordomo is 1.94.5, released 19 January 2000.
The official website warns that it will not work with Perl versions 5.001 and 5.005_01 specifically. It recommends to use Perl 4.036 or the latest version available. Support for Perl 4.036 may not be kept for the future.
History
With the advent of email, many mailing lists were maintained manually, with a list owner adding and removing participants by editing a text file. In 1984, LISTSERV was developed to run on IBM VM mainframes, and automated mailing lists on a large scale.
