VIPRE Email Security's engines are signature based which either score or don't score messages. 

This scoring is based on the content in the Header, Subject and Body of the message. 

• The Advanced Spam Filter always scores spam with a score of 210  
• The CloudMark Authority Engine always scores spam with a score of 5000

The sum on the results is the final score of a message which determines what action is to be taken.

In the policy for AntiSpam there is an upper and lower threshold. The default settings are 200 and 6000. 

• Messages with a score between 200 and 6000 are quarantined. 
• Messages with a score lower than 200 are delivered to the inbox. 
• Messages with a score over 6000 are automatically deleted. 
• Normal messages that are not spam should always have a final score of 0. 

If a regular message is scored incorrectly it is commonly referred to as a false positive.
