Spam Filter detects the email sender’s reputation score. The reputation scores
range from -10 (bad) to +10 (good). An email is classified as spam if the sender’s
reputation is below the spam threshold, or is classified as suspected spam if the
sender’s reputation is between the spam threshold and suspected spam
threshold. An email is not classified as spam if the sender’s reputation is above the
suspected spam threshold.
