Bayesian filtering
Explanation:
This is a type of filtering software that makes use of Bayesian logic to evaluate every incoming email that you receive, analyzing the header and content of the email to determinate if it is spam or not. It uses a preset of common words that are present in most spam emails, and it categorizes all received emails according to their probability to contain spam in trusted, or not trusted email. These categories are usually set by the user.
