Distributed e-mail Campaign Server

An electronic mailing list or email list is a special use of email that allows for widespread distribution of information to many Internet users. It is similar to a traditional mailing list - a list of names and addresses - as might be kept by an organization for sending publications to its members or customers. Electronic mailing lists usually are fully or partially automated through the use of special mailing list software and a reflector address that are set up on a server capable of receiving email. Incoming messages sent to the reflector address are processed by the software, and, depending on their content, are acted upon internally (in the case of messages containing commands directed at the software itself) or are distributed to all email addresses subscribed to the mailing list. Depending on the software, additional addresses may be set up for the purpose of sending commands. Many electronic mailing list servers have a special email address in which subscribers (or those who want to be subscribers) may send commands to the server to perform such tasks as subscribing and unsubscribing, temporarily halting the sending of messages to them, or changing available preferences. The common format for sending these commands is to send an email that contains simply, the command followed by the name of the electronic mailing list the command pertains to. Examples: subscribe anylist or subscribe anylist John Doe. Some list servers also allow people to subscribe, unsubscribe, and change preferences through a web-based interface.
