Abstract

The control section of a PDA incorporating a radio communication function adds respective subaddresses as identifiers to the mail address allocated to one account. The subaddresses classify the mail address as a plurality of destinations. The control section transmits an electronic mail to which one of the subaddresses is added to a mail server. The control section also discriminates the subaddress added as an identifier to an electronic mail by accessing a mailbox in the mail server, and receives the electronic mail to which the subaddress is added.

6. The apparatus according to claim 5, further comprising second reception means for receiving an electronic mail which has the predetermined mail address but which does not have the subaddress designated by said subaddress designating means.

7. An apparatus according to claim 5, further comprising:

reception condition storage means for storing reception conditions corresponding to the subaddress, and

wherein said reception means comprises means for determining whether or not a subaddress of an electronic mail to be received meets the reception condition stored in said reception condition storage means, and means for receiving the electronic mail when said determining means determines that the subaddress meets the reception condition.

8. An electronic mail communication apparatus comprising:

reception condition storage means for storing a reception condition corresponding to a subaddress added to an electronic mail, wherein the subaddress adds a new attribute to the electronic mail;

means for determining whether or not a subaddress of an electronic mail to be received meets the reception condition stored in said reception condition storage means; and

reception means for receiving the electronic mail to be received when said determining means determines that the subaddress thereof meets the reception condition.

9. The apparatus according to claim 8, further comprising second reception means for receiving the electronic mail to be received when said determining means determines that the subaddress thereof does not meet the reception condition, if the electronic mail to be received does have a predetermined mail address.

10. An electronic mail communication apparatus comprising:

reception means for receiving an electronic mail having a mail address and a subaddress which adds a new attribute to the electronic mail;

terminal information storage means for storing terminal information indicating a correspondence between each of a plurality of terminals and each of a plurality of subaddresses; and

notification means for determining which of the plurality of terminals is allowed to receive the electronic mail received by said reception means based on the terminal information, and for informing the determined terminal of reception of the electronic mail.

11. An electronic mail communication system comprising:

a base station; and

a plurality of electronic mail communication apparatuses,

wherein said base station comprises;

reception means for receiving an electronic mail having a mail address and a subaddress which adds a new attribute to the electronic mail;

storage means for storing apparatus information indicating a correspondence between each of said electronic mail communication apparatuses and each of a plurality of subaddresses; and

transmission means for transmitting the electronic mail received by said reception means to one of the mail communication apparatuses which is determined to be allowed to receive the electronic mail received by said reception means based on the apparatus information.

12. An electronic mail communication system comprising:

a mail server for managing electronic mails based on mail addresses allocated to accounts; and

an electronic mail communication apparatus communicated with said mail server,

wherein said mail server comprises;

reception means for receiving an electronic mail having a mail address and a subaddress which adds a new attribute to the electronic mail; and

storage means for classifying the electronic mail received by said reception means based on the subaddress.

13. The apparatus according to claim 12, wherein said mail server further comprises:

second storage means for storing apparatus information indicating a correspondence between each of a plurality of electronic mail communication apparatuses and each of a plurality of subaddresses; and

transmission means for transmitting the electronic mail received by said reception means to at least one of the mail communication apparatuses which is determined to be allowed to receive the electronic mail received said reception means based on the apparatus information.
