Abstract

An email system comprises a plurality of email servers connected by a data communications network. The email system avoids single points of failure by employing multiple email servers which self configure, without requiring dedicated servers, through self addressing and discovery and announcement protocols. An email server can act as a primary email server by executing an administration tool allowing an administrator to modify the configuration data set which the email servers utilize, and the primary email server will then announce the resulting change in the version level of the configuration data set to other email servers. Each email server will then determine and request any needed updates to its respective configuration data set from the primary email server or another email server. The resulting email system is: robust, avoiding single points of failure; scalable, as additional email processing capacity can be achieved by adding additional email servers; and is simple to administer as changes to the configuration data set can be made at any email server with a copy of the appropriate administration tool and such changes automatically propagate through the email system.
