54 Barracuda Spam Firewall Administrator’s Guide

To change the mode of your Barracuda Spam Firewall:

1. Go to the BASIC-->Administration page.

2. In the Operation Mode section, click Convert.

3. Click OK to confirm you want to change the mode of your Barracuda Spam Firewall.

A status bar displays the progress of switching your Barracuda Spam Firewall to outbound

mode. Once the switchover completes, your Barracuda Spam Firewall automatically reboots.

Enabling Users to Classify Messages from a Mail Client

• The Barracuda Spam Firewall provides access to a mail client plug-in that lets end users mark

messages as spam and not spam directly from their Outlook or Lotus Notes client. In addition,

the plug-in also automatically creates and maintains a personalized whitelist based on the user’s

behavior.

• The whitelist generated by the plug-in and the classifications made by the user only affect that

user’s individual Bayesian database and not the global Bayesian database. Changes to the global

Bayesian database can only be accomplished by the administrator on the

Basic > Message Log

page.

• This feature is not available on the Barracuda Spam Firewall 200.

To make the Outlook or Lotus Notes client plug-in available to your users:

1. On the Bayesian/Intent page, set the Allow Users to Download Plugins field to Yes.

2. If you’re enabling the Outlook plug-in, select the Outlook plug-in version you want your users

to download.

3. Click Save Changes.

A link to the mail plug-in appears at the bottom of the Administration interface login page so

users can download the plug-in, as shown in the following example:

Table 4.15:

Outlook Plu-In Description

Version 1 Allows users to classify messages as spam and not spam from their

Microsoft Outlook client.

Version 2 Contains all the functionality of version 1 and adds the automatic

whitelist feature. This feature automatically adds e-mail addresses to the

user’s individual whitelist based on the user’s behavior.

The Outlook plug-in version 2 automatically whitelists the following:

• The recipient address within each message sent by the user after the

new Outlook plug-in is installed. This only applies to messages sent

outside of the local mail server.

• The sender’s e-mail address for messages that the user classifies as

“not spam”.

• All e-mail addresses the user adds to their Contact list in Outlook.
