Configuring an increase in the spam rating of messages
You can configure the Anti-Spam settings affecting detection of a special message property - its spam rating. This special message property is assigned to messages based on their scan results. By default, Anti-Spam protection applies the low severity level. Depending on the severity level and the spam rating assigned after a scan, a message can be tagged as Spam or Probable spam.
