Majordomo is a free mailing list server that runs under UNIX. When e-mail is addressed to a Majordomo mailing list, it is automatically broadcast to everyone on the list. The result is similar to a newsgroup or forum, except that the messages are transmitted as e-mail and are therefore available only to individuals on the list.

Another popular mailing list server is LISTSERV.
