What is Spam Scoring, Bayesian Analysis, and Email Fingerprinting?
• Spam Scoring: The rules- based system (about 4000 rules) that looks for characteristics in the email. The Spam scores are used to determine what to do with the email. They do not contribute directly to the future analysis. The rules are updated via the Energize Updates Subscription. • Bayesian Analysis: Contributes to the Spam scoring. This is done using emails that you flag as either SPAM, or NOT SPAM in the message log. • Email Fingerprinting: The identification of exact or substantially similar emails via the Barracuda Central clearing house. When an email is identified as being Spam, it is also sent to our clearing house and fingerprinted. • Question: What is the capacity of the message logs on the appliance? The Barracuda Spam Firewall preserves log information for the last 500,000 messages and automatically removes old log information to maintain performance. Logs can be exported in real-time using syslog, a common tool supported by Unix systems as well as many third parties.
