Mailing List Mgmt.
Many list servers are available, running on a variety of operating systems.
The message distributor receives messages addresses to the list address and disributes them to the subscribers of the list. The list address usually has the name of the list as the username and the list server's hostname as the domain name. The message distributor also sends error messages to the list managers and, for moderated lists, sends messages to the list moderators for approval. Each list server has a site manager who is in charge of maintaining the list server program. The site manager is usually also the person who can create, rename, and delete lists.
