Mail sending and receiving devices send and receive e-mail program, and e-mail transmission and reception method

摘要

The invention enables conversion of elements of a mail message, neither requiring prior manual registration of conversion process details, nor increasing complexity of the system. When a mail message arrives at a computer (1), an analysis record generating means (2) produces an analysis record that gives its sender's identifier and a source mailer type. An analysis record storing means (3) stores such analysis records. Based on the identifiers in the analysis records stored in the analysis record storing means (3), a mailer type determining means (4) determines a destination mailer type of a received mail message. A conversion data storing means (5) stores conversion data specifying a conversion process corresponding to each specific combination of sender and recipient mailer types. A searching means (6) retrieves conversion data that matches with the combination of source and destination mailer types of the received message. If a match is found for that combination, a converting means (7) converts the mail message according to a conversion process specified by the retrieved conversion data.
