Communication apparatus with relay function and relay method

摘要

Two kinds of mail addresses, one for reception and the other for a relay, are stored beforehand. A relay is permitted only if the mail address of the received E-mail data is a relay mail address. A password name is deleted from the mail address of the received E-mail whose relay is permitted. Said mail address whose password name has been deleted is used as part of header information and transmitted to a destination terminal together with data.
