PURPOSE:To eliminate an increase in the amount of unnecessary storage and a temporary increase in traffic on the whole electronic mail system by transferring a communication document which is addressed to plural destinations successively to respective information processors. CONSTITUTION:A communication document received by an information processor with some address number is supplied to a reception decision part 512 to decide whether the amount of the storage of a storage device 503 is less than a specified value or not. When the amount is less than a specified value, the communication document is sent to a time setting part 513 and stored in the storage device 503; when the amount exceeds the specified value, a flag is set to a state BUSY and then the communication document is sent to a transmission destination setting part 514. The communication document stored in the device 503 is outputted to a terminal through an I/O control part 519 for terminals. A control part 15, on the other hand, operates a time setting part 517 periodically to set a next information processor through the transmission setting part 514 for all communication documents which are addressed to plural destinations in the device 503 when the difference between the reception time and current time is longer than specified time. |
