Chapter 3 Managing the Barracuda Spam Firewall ■ 25
Monitoring and Classifying Incoming Messages
Classifying Messages from the Administration Interface
Classifying messages is one of the easiest ways to set up rules that determine how the Barracuda Spam
Firewall handles incoming messages. The following table describes the buttons to use when classifying
messages on the BASIC-->Message Log page.
Button Description
Spam Classifies the message as spam in the Bayesian database.
The Bayesian database becomes active once 200 spam messages and 200 not
spam messages have been classified. At this point, the Barracuda Spam Firewall
begins scanning messages for any matchings to affect the scoring of the
messages.
If per-user quarantine is enabled, message classification performed by each
individual user is also applied to the Bayesian database.
To view the number of messages currently classified as Spam, go to the
BASIC--> Bayesian/Fingerprinting page.
Note: Messages marked as Spam are sent to Barracuda Networks for analysis
unless the Submit Email to Barracuda Networks field is set to No on the
BASIC-->Bayesian/Fingerprinting page discussed on page 46.
Not Spam Classifies the message as Not Spam in the Bayesian database.
The Bayesian database becomes active once 200 spam messages and 200 not
spam messages have been classified. At this point, the Barracuda Spam Firewall
begins scanning messages for any matchings to affect the scoring of the
messages.
If per-user quarantine is enabled, message classification performed by each
individual user is also applied to the Bayesian database.
To view the number of messages currently classified as Not Spam, go to the
BASIC-->Bayesian/Fingerprinting page.
Whitelist Adds the sender of the message to your whitelist. Messages from whitelisted
senders do not receive a spam score.
Messages from whitelisted senders still go through:
• Virus checking
• Attachment type filtering (discussed on page 39)
• Blocking filters for header, body and subject content (discussed on page 40)
Un-Whitelist Removes the sender of the message from the whitelist.
Clear Message
Log
Clears all the logs that are currently displayed. This does not clear the Bayesian
database that contains the rules you have set up for incoming messages.
