Anti-Spam
Use the page to configure how to handle messages with spam characteristics. A cumulative spam score is assigned to each scanned message based on results of anti-spam tests. This score determines the relative likelihood that a message is spam and classifies messages in one of three ways: not spam, medium probability of being spam, or high probability of being spam.
The Policy: Anti-Spam page allows you to handle Mail with high spam scores (almost certainly spam) differently from Mail with medium spam scores (probably spam), and bounce messages.
Each row of the Anti-Spam policy configuration table is a policy rule with options for defining the relevant users and the actions to be taken. By default, there is one rule defined for each of the two spam categories. Mail with high spam scores is discarded for all inbound messages, and quarantined for all outbound messages. Mail with medium spam scores is quarantined for all users. Mails which encounter spam engine errors cannot be sent to the policy engine, and hence, are quarantined.
