Spam Filter

A spam filter is an automated system that evaluates incoming emails and blocks or redirects those that appear unsolicited or harmful.

Spam filters use rules, machine learning, and reputation data to classify emails as spam or legitimate. They protect users from unwanted messages but can also block legitimate emails if sender practices are poor. Understanding how filters work helps senders adjust their strategies to avoid being flagged.
