Table 4.4:

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 that time, the

Barracuda Spam Firewall begins scanning messages to determine how

closely they match the messages identified as spam. This comparison

determines a message’s spam score.

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/Intent page.

Note: 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/Intent page covered on page 56.

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 that time, the

Barracuda Spam Firewall begins scanning messages to determine how

closely they match the messages identified as not spam. This

comparison determines a message’s spam score.

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/Intent page.

Whitelist Adds the sender of the message to the global whitelist. Messages from

whitelisted senders do not receive a spam score.

Messages from whitelisted senders still go through:

• Virus checking

• Attachment type filtering (covered on page 64)

• Blocking filters for header, body and subject content (covered

Chapter 5 Using the Block and Accept Filters)

Un-Whitelist Removes the sender of the message from the global 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.
