A communication device allows a user to get access from the outside via an external
public line to obtain e-mail data stored in a device connected to an internal system
via a computer network such as a LAN without causing a reduction in security. More
specifically, the communication device is connected to a LAN via a LAN I/F and
also connected to the public line via a line I/F. If the communication device receives
a remote operation command via the public line, a CPU of the communication device
gets access to a post office of an e-mail server so as to get e-mail data in accordance
with the remote operation command. The obtained e-mail data is converted to facsimile
image data and transmitted by means of facsimile to a specified destination.
