Spam Assassin

SpamAssassin and SpamBox allow you to identify spam mail and flag it or prevent it from entering your inbox. SpamAssassin is an automated email filtering system that attempts to identify spam messages based on the content of the email's headers and body. SpamBox will deliver any emails identified as spam by SpamAssassin into a separate mail folder named "spam". This "spam" folder will fill up and should be emptied regularly.
