PROBLEM TO BE SOLVED: To provide an electronic mail transmission/reception device or the like which efficiently monitors a received mail and generates a return mail. SOLUTION: In a step A7, it is discriminated whether an item 'Subject' and a text of a taken-in mail and those of an already stored mail coincide with each other or not. If they completely coincide as the result of this discrimination, it is unnecessary to preserve the taken-in electronic mail, and a part of a storage electronic mail box for mail preservation is unnecessarily occupied if the reception electronic mail of the same contents is preserved. However, both electronic mails are different by an item 'From' indicating a transmitter as a matter of course, and therefore, the item 'From' in a reception mail buffer is added to a stored mail buffer (step A8) and is preserved in the storage electronic mail box (step A9) if the item 'Subject' and the text completely coincide. |
