Automated spam filter updating by tracking user navigation

An email filter updating system includes a tracking component, and a logic component. The tracking component is provided to track user navigation. This tracking compiles information about websites the user has visited and presumably may "trust" in the event an email associated with one such site or application is later received by the user's email application. The logic component uses information and a set of configurable rule-based criteria to output a characterization that a particular email message has been initiated from a site that the user has visited or should otherwise trust. The characterization is then provided to the email filter to control whether in-bound email is passed to the user's email client inbox. Further, the logic component is operative to generate filter update commands that update the email filter in an automated manner, i.e., without user input.
