PROBLEM TO BE SOLVED: To provide an electronic mail transmitting and receiving device, etc., which eliminates the need for special operation such as the manual attachment of importance and can estimate the importance of individual electronic mail with high precision.;SOLUTION: The electronic mail transmitting and receiving device which sends and receives electronic mail through a wired or wireless network is equipped with an importance decision part 201b which makes a mechanical and probabilistic decision on the importance of mail received by an electronic mail reception part 200, an electronic mail termination notice part 202 which notifies an operator of the termination of new mail, an operation time monitor part 201c which computes the elapsed time from the termination notice date and time to the unsealing date and time of mail having been unsealed or the elapsed time from the termination notice date and time to the current date and time of unsealed mail, and an importance learning part 201d which increases the importance when the elapsed time of the former is shorter than a specific threshold or decreases the importance when the elapsed time of the latter is longer.;COPYRIGHT: (C)2002,JPO
