Server colocation Reviewing the basics
Most times all that happens is that your email address is added to a distribution list. However, in some cases, this curiousity opens a Pandoras box full of harmful viruses that create havoc with your computer network. You need a Barracuda firewall to kill those viruses before they cause any damage and to block that spam from ever reaching your network in the first place. The Barracuda firewall is a best in class anti spam security system specifically designed to protect email servers from phishing, spyware, viruses and spam. It employs twelve distinct layers of defense, including network denial of service protection, rate control, IP reputation analysis, sender authentication, recipient verification, virus scanning, policy, spam fingerprint check, intent analysis, image analysis, Bayesian analysis, and rule based scoring.
