SPAM Filter

Overview

A spam filter is a system that automatically detects and blocks unwanted messages like phishing, malware, and junk ads while allowing legitimate communication. It uses techniques such as keyword rules, blacklists/whitelists, Bayesian filtering, header and content analysis, and heuristic scoring. Modern filters leverage AI and machine learning to adapt to new spam tactics. They can operate at email client, network, application, or cloud levels. Challenges include false positives, false negatives, and evolving threats. Best practices include regular updates, multi-layered filtering, email authentication (SPF, DKIM, DMARC), and user feedback for accuracy.
