<p>A handheld terminal has a function of saving a received electronic mail into a memory. A CPU specifies a sender of the electronic mail received this time, and detects from the memory the electronic mail received from this sender in the past. If the specified sender is registered on a list of candidates to be deleted, and a receiving date of the electronic mail detected from the memory is older than a week or more days, the CPU deletes the detected electronic mail from the memory.</p> |
