METHOD FOR GENERATING REPUTATION VALUE OF SENDER AND SPAM FILTERING METHOD

A method for generating a reputation value of a sender includes: obtaining non-spam logs in a specified period; calculating an initial reputation value of a target sender according to sender identifications and recipient identifications of the non-spam logs as well as the number of emails sent by senders of the non-spam logs; calculating a transferred reputation value of the target sender according to the sender identifications of the non-spam logs and the number of the emails sent by the senders of the non-spam logs; and calculating a current reputation value of the target sender according to the initial reputation value and the transferred reputation value of the target sender. The method can accurately calculate the reputation value of the sender without relying on an email sending history of the sender, thereby effectively preventing the reputation value of the sender from being increased by cheating.
