If you ever find that you're receiving a lot of junk emails known as "spam emails" or "unsolicited emails", please enable the Spam Assassin. It is an automated mail filter that uses a wide range of heuristic algorithms on mail headers and message body text to identity "SPAM". Once identified, the mail is tagged as SPAM for later filtering using the users' desktop mail client. .
