Abstract

A mail center management system includes a first network accommodating a plurality of subscriber terminals via lines, and a plurality of mail devices connected to the first network. Each of the mail devices, which has a device number and subscriber information about all the subscriber terminals, includes a storage medium for storing mails received from the subscriber terminals. A second network connects the mail devices to each other and transfers the mails between the mail devices. Each of the mail devices includes a first part for determining whether a request to transfer from a first one of the subscriber terminals to a second one of the subscriber terminals includes a subscriber number of the second one of the subscriber terminals or the device number of one of the mail devices together with the subscriber number. Further, each of the mail devices includes a second part for storing, via the second network, the mail in the storage medium of one of the mail devices to which the first and second ones of the subscriber terminals are connected when the first means determines that the request includes no device number and for storing, via the first and second networks, the mail in the storage medium of one of the mail devices to which the second one of the mail devices is connected when the first means determines that the request includes the device number together with the subscriber number.
