A spam filter is a program used to detect unsolicited email to prevent spam from making it to a user's inbox. Filters use heuristics, keyword scans, whitelists and blacklists, and other processes. The filters are placed on email and ISP servers, in anti-spam software, and in anti-phishing browsers. Also see: Bayesian filter, heuristic analysis.
