SpamAssassin

SpamAssassin is an open-source software tool designed to identify and filter out spam emails. It analyzes incoming messages using a variety of techniques, such as checking for specific keywords, patterns, and known spam signatures. By assigning a score based on these factors, SpamAssassin determines whether an email is likely to be spam. If the score exceeds a certain threshold, the email can be marked as spam or filtered out entirely. This helps users manage their inboxes and reduces unwanted, potentially harmful emails, enhancing overall email experience and security.
