PROBLEM TO BE SOLVED: To classify and store received messages and thereby, lighten the burden of a classifying process on a user, by learning a key word which is common to the messages as a new classification condition, and classifying and storing subsequent received messages in a storage means under the classification condition. SOLUTION: A storage control means 2 stores a received message in a corresponding classification of a 1st storage means 3 when the message meets classification conditions. When the received message meets none of the classification conditions, it is stored in a 2nd storage means 4. The message receiver when receiving the message stored in the 2nd storage means 4 opens the message to confirm its contents, and classifies the message as predetermined and stores it in the 1st storage means 3. A classification condition learning means 6 reads respective stored messages on the basis of respective classifications in the 1st storage means 3 and learns the classification conditions corresponding to the respective classifications on the basis of extracted key words. |
