Sender address setting when generating return mail

A return mail generating apparatus that is connected to a mail server via a network to generate a return mail in reply to a received original mail, comprising:

• a program memory that stores a program, a data memory that stores data, a processor that executes the program and a communications apparatus that performs communications processing with the mail server;
• wherein said data memory has an address storage area that stores at least one mail address that is currently available to a user;
• and
• wherein the program causes said processor to execute:
• managing the mail address that is currently available to the user in the address storage area;
• causing the communications apparatus to receive the original mail, using the mail address of the user as a destination address, from the mail server via the network;
• determining whether the destination address of the received original mail is stored in the address storage area at the time of generating the return mail in reply to the received original mail;
• setting the destination address of the received original mail to a sender address of the return mail when the destination address is stored in the address storage area;
• and
• setting one of the mail addresses stored in the address storage area to the sender address of the return mail when the destination address is not stored in the address storage area.

A return mail generating method executed by a computer apparatus connected to a mail server via a network comprising:

• receiving an original mail using the mail address of the user as a destination address from the mail server via the network;
• determining whether the destination address of the received original mail is stored in the address storage area at the time of generating a return mail in reply to the received original mail;
• setting the destination address of the received original mail to a sender address of the return mail when the destination address is stored in the address storage area;
• and
• setting one of the mail addresses stored in the address storage area to the sender address of the return mail when the destination address is not stored in the address storage area.

• managing a mail address that is currently available to a user in an address storage area provided in a data memory;
• receiving an original mail using the mail address of the user as a destination address from the mail server via the network;
• determining whether the destination address of the received original mail is stored in the address storage area at the time of generating a return mail in reply to the received original mail;
• setting the destination address of the received mail to a sender address of the return mail when the destination address is stored in the address storage area;
• and
• setting one of the mail addresses stored in the address storage area to the sender address of the return mail when the destination address is not stored in the address storage area.

A carrier wave superimposed with a data signal of a program, which is executed by a computer apparatus connected to a mail server via a network, wherein the program causes the computer to execute:

• managing a mail address that is currently available to a user in an address storage area provided in a data memory;
• receiving an original mail using the mail address of the user as a destination address from the mail server via the network;
• determining whether the destination address of the received original mail is stored in the address storage area at the time of generating a return mail in reply to the received original mail;
• setting the destination address of the received mail to a sender address of the return mail when the destination address is stored in the address storage area;
• and
• setting one of the mail addresses stored in the address storage area to the sender address of the return mail when the destination address is not stored in the address storage area.
