Hardware firewall, a review of the basics
Once the spam is identified as such, you can have it discarded or placed in a holding area. Spam emails are identified by the Barracuda firewall before it even reaches your inbox. This fact alone can save you hours you would normally have to spend going through emails everyday. Business owners appreciate the amount of time they have to use up just to clean up their emails. The Barracuda firewall protection system has certain IP addresses already identified as spam and can keep these emails from ever getting through to your inbox in the first place.
