spam score

The score assigned to a message by the anti-spam engine that indicates the relative likelihood that the message is spam. Anti-spam rules consist of a test definition and a "weight". If the test matches the message, the corresponding weight is added to the message's total spam score. Generally, multiple rules must be triggered by a message in order to result in a spam score high enough for an action to be taken. SophosLabs constantly analyzes emerging spam techniques and updates the ES4000 and PureMessage anti-spam rule sets accordingly.
