PURPOSE:To prevent the occurrence of missing or alteration of mail by adding designation information to identify between a text area whose contents can not be corrected and a write area to which comment, etc., can be freely written to the mail by a mail sending person. CONSTITUTION:When a mail generating person designates the write area, a write control part 13 receives it, and adds it as a write area control table to the corresponding page of the mail. Next, a destination to which the mail is circulated is designated. The list of the circulating destination designated by the mail generating person is received by a mail destination control part 14, and is added as destination control information in the mail header to the mail. The sent mail is circulated in conformity to designated circulating order. A circulative receiving person takes out the mail from a mail storage part 3, and displays it on the display of an output part 6. At that time, the text area and the write area are indicated by different colors so as to indicate clearly a writable area to the circulative receiving person. Thus, is can be protected from the alteration by the circulative receiving person.
