What is SpamAssassin?

SpamAssassin is a mail filter that identifies spam. It is an intelligent email filter that uses a diverse range of tests to identify unsolicited bulk email, more commonly known as Spam. These tests are applied to email headers and content to classify email using advanced statistical methods. By using multiple "tests" to determine if an email is spam or not, the likelihood of a message being incorrectly flagged is reduced.

At Pure Energy Systems, Spamassassin filtering is included with every shared linux web hosting account free of charge.
