Barracuda Networks Spam Firewall Outbound Quick Start Manual
Barracuda Spam Firewall Outbound - Quick Start Guide
The Barracuda Spam Firewall is a spam and virus filtering appliance that ensures all
emails leaving your networks is virus-free and legitimate. It prevents individuals from
unintentionally or intentionally using your organization’s network to send viruses or spam.
It is physically installed on your network and assigned an IP address as a node on your
internal network. It is common for the Barracuda Spam Firewall to be installed in the DMZ
area of your network or behind a traditional firewall. Once configured, any outgoing
message that contains a virus or scored above the quarantine level is automatically
blocked and placed in the Quarantine Box.
