Inventor: SOSHI MASATO
IPC: H04L12/58
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus that transfers automatically a received mail to pre-registered addresses when a mail data is received. SOLUTION: A key data for the specified item of mail data, a transfer address for the received mail, and a transfer procedure are set in an automatic transfer table. When the mail arrives, the automatic transfer table is referred (step A11 and 12) and checks whether the automatic transfer table contains the key data in the specified item or not (step A13 to 15). If the key data is contained, the mail automatically is transferred by the specified transmission process (step A17 and 18) to the transfer address that is not described in the received mail out of the automatic transfer table (step A16).
