Chapter 3 Managing the Barracuda Spam Firewall ■ 29

Enabling and Disabling Virus Checking and Notification

Virus scanning is automatically enabled on the Barracuda Spam Firewall, and the system checks for

definition updates on a regular basis (hourly by default).

Use the BASIC-->Virus Checking page to configure the virus checking and notification settings

described in the following table. Click Save Changes after making any modifications to this page.

Setting Up Quarantine

By default, the Barracuda Spam Firewall does not come configured to quarantine messages.

To set up quarantine functionality on your system:

1. Enable quarantine functionality using the Spam Scoring Limits. Refer to Configuring the Global

Spam Scoring Limits on page 28 for more information.

2. Go to the BASIC-->Quarantine page.

3. Select the quarantine type, as described on page 30.

4. Do one of the following:

– For global quarantine type, enter the global quarantine delivery address, as described on page 30.

– For per-user quarantine type, configure the per-user quarantine settings, as described on page 31.

5. Click Save Changes.

Setting Description

Virus Scanning

Enabled:

When virus scanning is enabled, all messages are automatically scanned

for viruses. The Barracuda Spam Firewall always blocks a message that

contains a virus. The message is never quarantined and is not delivered to

the intended recipient even if the sender has been whitelisted. It is

recommended you keep virus scanning enabled.

Note: On the Barracuda Spam Firewall 400 and 600 you can enable and

disable virus checking on a per-domain basis from the DOMAINS tab. For

more information, refer to Managing and Configuring Domains on

page 54.

Notify Intended

Recipient of Virus

Interception:

Determines whether the Barracuda Spam Firewall notifies a recipient when

an incoming email is blocked because the message contained a virus.

Notify Sender of Virus

Interception:

Determines whether the Barracuda Spam Firewall notifies the sender that

their email has been blocked because it contained a virus.

You should keep this option set to No to prevent the Barracuda Spam

Firewall from sending mass email notification traffic in the event of a

widespread virus outbreak.
