An electronic mail communication system comprises a base station 1 and at least one portable terminal 2. A mail server 3 of the base station 1 transmits only the header portion of the electronic mail to the portable terminal 2. The portable terminal 2 receiving the header portion compares the transmitter mail address extracted from the header portion with reception target mail addresses registered in the portable terminal 2 in advance by the user. If the transmitter mail address is coincident with one of the registered reception target mail addresses, the portable terminal 2 requests the mail server 3 to transmit the mail body of the electronic mail, and if the transmitter mail address is not coincident with any registered reception target mail address, the portable terminal 2 requests the mail server 3 to delete the mail body.
