A facsimile mail system including subscriber terminals, an exchange and a facsimile mail apparatus. Given a request from a subscriber terminal for connection to the facsimile mail apparatus, the exchange adds an originator identification number to that necessary information about a mail service which is entered from the subscriber terminal. The necessary information supplemented by the originator identification number is transferred from the exchange to the facsimile mail apparatus where the information is converted to a mail function code for internal processing. As per internally stored information, the facsimile mail apparatus decides whether or not to permit the connection. When the connection is permitted, a connection enable response is returned to the exchange. In turn, the exchange establishes a line connection between the subscriber terminal in question and the facsimile mail apparatus.
