Detected mail notification receiving server

摘要

The detection conditions acquisition unit included in the mobile communication terminal acquires detection condition data including a letter string from the detection conditions distribution server and stores the data in the detection conditions storage unit. The detection unit extracts, from among the mails received by the mail receiving unit, mails including a letter string included in the detection condition data stored in the detection conditions storage unit. Thus, the mobile communication terminal may acquire a letter string specified by the detection conditions distribution server to detect specific mail. Therefore, a letter string for detecting a particular mail is specified easily.
