67 Mail POP Redundancy Group

The Mail POP Redundancy Group target is a grouping of POP agent monitored targets that have identical configuration, characteristics, and functionality. While a single POP server instance is vulnerable to the failure of its host or system, a redundant group of POP servers continues to function despite the loss of a POP server instance, hiding any such failure from clients, and allowing other POP server instances in the group to service the requests.
