摘要

The method involves administering electronic-mail (e-mail) addresses by a honeypot mail system (8), and receiving unwanted e-mails by the system. An e-mail of the e-mail addresses administered by the system is sent to exactly check whether the e-mail actually concerns the unwanted e-mail e.g. Spam e-mail, Phishing e-mail, Virsus e-mail or Trojan e-mail. The e-mail is filtered with a data base, in which the e-Mail addresses, contents and subjects and internet protocol (IP) address of a sender of the unwanted e-mail are enclosed.
