Majordomo is a program which automates the management of Internet mailing
lists. Commands are sent to Majordomo via electronic mail to handle all
aspects of list maintenance. Once a list is set up, virtually all operations
can be performed remotely, requiring no intervention upon the postmaster of
the list site.

     majordomo - n: a person who speaks, makes arrangements, or takes
     charge for another. From latin "major domus" - "master of the
     house".
