Overriding the Per-User Quarantine Account Settings
The Per-User Quarantine Account Override section on the BASIC-->Quarantine page lets you change
the default quarantine configuration on a per-user basis.
For example, if the default quarantine configuration is set to disabled, you can enable per-user
quarantine functionality for specific users by listing their email addresses in this section.
This feature is not available on the Barracuda Spam Firewall 200.
To override the default quarantine configuration:
1. In the User Accounts box, enter the email addresses of the users whose quarantine settings you
want to override.
2. For the Enable User(s) Quarantine option, select one of the following:
– Ye s to enable quarantine for the specified user accounts.
– No to disable quarantine for those users.
3. Click Save Changes.
Configuring System IP Information
The BASIC-->IP Configuration page contains the network and mail server configuration for your
Barracuda Spam Firewall.
The following table describes each of the sections on this page.
Section Description
TCP/IP
Configuration
The IP address, subnet mask, and default gateway of the Barracuda Spam
Firewall.
TCP port is the port on which the Barracuda Spam Firewall receives inbound
email. This is usually port 25.
Destination Mail
Server TCP/IP
Configuration
Server Name/IP: The hostname or IP address of your destination email server,
for example mail.yourdomain.com. This is the mail server that receives email
after it has been checked for spam and viruses.
You should specify your mail server’s hostname rather than its IP address so
the destination mail server can be moved and DNS updated at any time without
any changes to the Barracuda Spam Firewall.
TCP port is the port on which the destination mail server receives inbound
email. This is usually port 25.
Valid Test Email Address: To test that the Barracuda Spam Firewall can
successfully send email messages, enter an address in this field and click Test
SMTP Connection. The system sends a message to the email address you
specify. The From address in this email is [e-mail].
DNS Configuration Lists the primary and secondary DNS servers you use on your network.
You should specify a primary and secondary DNS Server. Certain features of
the Barracuda Spam Firewall, such as Fake Sender Domain detection, rely on
DNS availability.
