Source: Use Spamassassin for better SPAM detection


The Linux operating system is typically immune to viruses attached to email. But it is not immune to SPAM. Left unfiltered your inbox would quickly fill up with more SPAM than you care to delete. What is worse is owning a mail server and not protecting your users from a barrage of SPAM.
By employing Spamassassin you can set up an outstanding SPAM filter system that will protect your users. It’s not as simple as double clicking an .exe file to install, but the end results will be worth the time and effort.
