Behavior is analyzed for each client attempting a connection to an uncategorized target. IP addresses and URIs are evaluated toward placement in either a Trusted target store or an Anomalous target store. The accumulated content of Anomalous target store is provided back to the Network Service Subscriber Clients. Warnings and tools are presented when appropriate.

  • Publication number: 20100250579
    Abstract: A method for operating an apparatus to recall email which has already passed through a spam filter to user mailboxes. An apparatus stores a highly efficient database for a brief period of time after an email is received, filtered, and transmitted to an email server. Message id, recipient, connecting IP address and other spam attributes are stored in a searchable format. After receiving updated spam attributes, a spam filter apparatus under software control queries the database for messages that were not detected as spam before transmittal to the email clients and servers, and sends spam recall messages. Improved email clients and servers adapted by software instructions, move or modify email user mailboxes upon receipt of the spam recall.
