Abstract: An encryption error monitoring system for checking packets transmitted between a private network and an external network. The system includes includes a detector module (60) which is connected to receive the packet for determining whether or not the packet is successfully encrypted in accordance with a specific security protocol such as IPSec (Internet Protocol Security). The detector module reads from the packet a sender's address and a destination address, and provides an error signal when the packet is judged not to be successfully encrypted. A manager module (80) is connected to the detector module within the private network to create, upon receipt of the error signal, a report including the sender's address and the destination address with regard to the packet judged not to be successfully encrypted.

Further, the electronic reception terminal device decrypts the encrypted mail.

Abstract: A communication control apparatus detects a predetermined signal type in accordance with SMTP protocol from a first interface section connected to an IFAX. The communication control apparatus controls communication with the IFAX in accordance with the SMTP protocol when the predetermined signal type is detected. On the other hand, the communication control apparatus controls communication with a server via a second interface section connected to a network, to which the IFAX is connected. The network is managed by the server. The communication control apparatus receives email data from the IFAX, converts it into HTML data, and transmits the HTML data to the server. Accordingly, the communication control apparatus is capable of enabling the IFAX to operate on the network managed by a HTTP protocol.

Abstract: An Internet facsimile apparatus is provided such that, even when an electronic mail includes plural data files that cannot be processed by the apparatus, prints the electronic mail normally. The apparatus includes a mail analyzer that determines whether a received electronic mail includes data that cannot be printed by a printer. When the electronic mail includes such unprintable data, the unprintable data is transmitted to a conversion server. The apparatus receives back printable data converted from the unprintable data from the conversion server and prints the printable data. The apparatus stores an indication that a plurality of printable data converted from a plurality of unprintable data has been received back from the conversion server. A message ID processor checks the indication, and the printer is informed regarding an object to be printed in accordance with the result of checking by the message ID processor.
