This information contributes to the Barracuda Reputation System, which gives the Barracuda Spam & Virus Firewall the 83ability to block or allow a message based on the sender's IP address. In addition to IP reputation, the Barracuda Central team maintains reputation on URLs, which gives the Barracuda Spam & Virus Firewall the ability to quickly block an email based on a poorly-rated URL contained in the message. By combining both the IP and reputation data, Barracuda Networks can easily determine whether a message is spam or legitimate email. Once identified, Barracuda Central can implement countermeasures to mitigate these threats. </p> 84 85<p>Barracuda Reputation is one of the many techniques Barracuda Networks employs within the Barracuda Spam & Virus Firewall to reinforce its superior 95 percent spam accuracy rate.</p> 86 87 88 <div id="lookups-pages" style="padding-top: 10px"> 89 <div id="lookup-reputation" class="tmenu-page"> 90 <div class="yui-g"> 91 <div class="yui-u"> 92 <p>The Barracuda Reputation System is a real-time database of IP addresses that have a "poor" reputation for sending valid emails.
