A mailing list is a group of people who share messages with one another through the medium of email list. Interest groups, your business' customers, your company staff – these are just a few examples of typical mailing list audiences.
When you send mail to a mailing list's address it reaches everyone who is subscribed to that list. If you are subscribed to email list, you will receive all email messages sent to the email list by your fellow subscribers, people who are on the same list as you. So, email list is like a magazine you subscribe to and where email list members instantly publish their messages by sending them to the email list.
Mailing list operations are managed by listservers. A listserver is a program that administers the activity of the list and it has its own address to which you send requests to subscribe or unsubscribe; to find out who else is a part of the list; to find out what the list is about; and so on. A list address is an email address that you use to send messages that you would like to share with the other members of the list. There are several listserver programs like Listserv or Majordomo and a listserver address could, for example, be 'majordomo@yourdomainname.com. Majordomo controls a list of addresses for some mail transport system (like sendmail) to handle. Majordomo itself performs no mail delivery. It is used by CloudBlue Commerce to manage mailing lists.
The purpose of Majordomo is to automate the management of Internet mailing lists. Handling all aspects of list maintenance by Majordomo can be achieved by sending commands via email. Once a list is set up, virtually all operations can be performed remotely, requiring no intervention by the postmaster of the list site.
Mailing lists to be efficient means of communication require proper administration by list owners. The list owner is the person (or persons) who runs day-to-day operations of a mailing list by responding to mail messages coming from Majordomo. Each mailing list operated by Majordomo can have its own list owners.
CloudBlue Commerce makes it much easier for list owners to manage Majordomo's configuration.
