    摘要: A system and method are disclosed for improving a statistical message classifier. A message may be tested with a machine classifier, wherein the machine classifier is capable of making a classification on the message. In the event the message is classifiable by the machine classifier, the statistical message classifier is updated according to the reliable classification made by the machine classifier. The message may also be tested with a first classifier. In the event that the message is not classifiable by the first classifier, it is tested with a second classifier, wherein the second classifier is capable of making a second classification. In the event that the message is classifiable by the second classifier, the statistical message classifier is updated according to the second classification.

    摘要: A local gateway device receives email across the internet from a sender of the email and forwards it across the internet to an email filtering system. The email filtering system analyzes the email to determine whether it is spam, phishing or contains a virus and sends it back to the local gateway device along with the filtered determination. The local gateway device forwards the received email and the filtered determination to a local junk store which handles the email appropriately. For example, if the email has been determined to be spam, phishing or containing a virus, the junk store can quarantine the email and if the email has been determined to be non-spun and/or not phishing and/or not containing a virus, the junk store can forward the email to a local mail server for delivery.

    摘要: Information concerning a plurality of identified threats provided by a plurality of preselected sources is stored in memory. An e-mail message may be received over a communication network. The received e-mail message is separated into a plurality of components. The stored information is searched to identify a reputation score associated with each of the plurality of components. It is then determined whether the e-mail is a threat based on the identified reputation score of each of the plurality of components. The determination is sent to a designated recipient.
