Abstract

An electronic mail system in which a mail management method is improved in order to reduce the complexity and labour of handling transmitted information so that its convenience is increased. In an electronic mail system in which a plurality of data processing systems exchange messages through mailboxes MB utilizing the stored and forward system, the data processing system which receives a mail M transferred from the mailbox MB is provided with an electronic mail terminal utility. When the data processing system receives the mail M, the electronic mail terminal utility classifies a data file written in the mail M according to specific data contained in the mail M and stores the data file in an appropriate folder based on a result of the classification.

wherein the management means includes (1) a folder specification information searching unit for searching the envelope part for folder specification information and selecting a folder used to store the attachment file in accordance with the folder specification information if it exists in the envelope part, (2) a folder creating unit for creating a new folder if the folder selected by the folder specification information searching unit does not exist, and (3) an attachment file attribute information searching unit for extracting file attribute information from the attachment file and selecting a folder used to store the attachment file in accordance with the extracted file attribute information if the folder specification information does not exist in the envelope part.

9. An electronic mail processing system according to claim 8, wherein the attachment file attribute information searching unit comprises (1) a table for showing the association between the file attribute information and folders, and (2) a table search unit for searching the table in accordance with the extracted file attribute information to classify the attachment file.

20. An electronic mail processing system according to claim 1, wherein the folder selection unit comprises:

a table for showing the association between the file attribute information and the folders; and

a table search unit for searching the table in accordance with the extracted file attribute information in order to classify the attachment file.

10. An electronic mail processing method comprising:
