Kind Code:
A1
Abstract:
A sender profile generation unit (123) generates a sender profile of a subject mail on the basis of the subject mail, which is an e-mail to be inspected. A body text data extraction unit (124) extracts body text data corresponding to the sender profile of the subject mail from a body text list file in which one or more pieces of body text data relating to one or more suspicious mails and one or more sender profiles relating to the one or more suspicious mails are associated with each other. A body text inspection unit (125) compares a body text of the subject mail with the body text data extracted from the body text list file, and determines whether the subject mail is a suspicious mail or not on the basis of a result of the comparison.
