Managing Accounts and Domains 75

• Download Backup File to save the last backup file to a specified location.

• Create Backup File Now to create a new backup file instead of saving the backup file that

already exists.

2. Save the user setting backup file (pu_config.tgz) to your local system.

To restore user settings:

1. From the Users > User Backup/Restore page, click Browse.

2. Locate the user settings backup file (pu_config.tgz) and click Upload Now.

Setting Retention Policies

Retention policies help you automatically manage your users’ quarantine areas by controlling how

much space is available on the Barracuda Spam Firewall for a user’s quarantine messages.

You can control the amount of space used for quarantine areas using:

• Size restrictions that determine the size each user’s quarantine

• Age restrictions that determine the period of time messages are kept in a user’s quarantine area

It is recommended you train your users to manage their own quarantine areas and not rely on the

retention policies to automatically remove messages. Relying on the Barracuda Spam Firewall to

automatically manage quarantine areas can impact system performance.

In addition to using retention policies to manage quarantine areas, you can also select

User >

Accounts View to view the size of each user’s quarantine area. You can then contact users directly if

they have a large quarantine area that they need to manage.

Adding New Domains

• If your Barracuda Spam Firewall is responsible for filtering messages for more than one e-mail

server or domain, you need to enter the domains associated with each mail server on the

Domains > Domain Manager page.

• If you have the Barracuda Spam Firewall 400, 600, or 800 you can also set spam scoring,

quarantine type and spam/virus checking on a per-domain basis.

To add and configure domains:

1. Select Domains > Domain Manager.

2. In the Advanced Domain Configuration section, enter the domain associated with your other

mail server, and click

Add Domain.

The domain appears in the table.

3. Click Edit Domain next to the domain you just added.

The

Domain Edit page opens.

Note

When you enable retention policies, keep in mind that if your system has been accumulating mail

without retention policies then the first day retention policies that are enabled may have an impact

on system performance. The longer a system runs without retention policies the larger the

performance impact. After the first day or two, the load stabilizes as the system is able to keep large

quarantine fluctuations to a minimum. Retention policies are run starting at approximately 02:30

AM.
