When a communication regulation determining block determines that E-mail communication is regulated when an E-mail processing block prepares for communication or initiates communication, information indicative of alternative communicating section using another communication path in which communication is not regulated is displayed on a user interface section. Therefore, it is possible to easily check which communicating section is effective when communication regulation occurs, and hence the user can easily make a determination such as that alternative communicating section is used, or that communication is aborted.
