List owners are individuals responsible for list administration via mail commands. Thus, list owners may be remotely located. Each list has to have at least one list owner. In addition, they may moderate their lists and they receive various error messages pertaining to their lists.
All administrative commands are author authenticated and password protected.
Whenever a message cannot be author authenticated, the list's owner and manager are notified. List owners may assign various parts of these responsibilities to other people. List owners may assign moderators, whose function is to approve messages and guide the on-line discussion, subscription managers, whose function is to add or remove individuals to the list, and recipients of error messages, whose function is to contact users who generate error messages by submitting invalid commands and educate them as to the error, also to remove users whose addresses are no longer valid.
