Set Spam Tolerance Level
Spam Tolerance Level defines the threshold, which if exceeded, classifies an email as spam. Each email is passed through a spam engine and if spam words are found, the score is increased. After the entire mail is scanned, if the score exceeds the tolerance level you set below, then that email is marked as spam.

Increasing this threshold will allow more spam to go undetected while decreasing it may result in more legitimate mail getting marked as spam.

Low Greatest amount of spam and legitimate mail is marked as spam. (Score - 5)
Medium Moderate amount of spam and legitimate mail is marked as spam. (Score - 10)
High Least amount of spam and legitimate mail is marked as spam. (Score - 15)
