The SpamWall Anti-Spam Firewall is a hosted email gateway appliance incorporating a comprehensive Spam and Virus filtering solution that ensures email arriving at your mail server - and network - is Spam and Virus free.
The SpamWall system provides an integrated Anti-Spam and Anti-Virus solution offering complete email protection at the "network perimeter" level, before unwanted or potentially dangerous and costly email reaches your network or mail server.
The SpamWall is positioned "in front" of your existing email server and is able to immediately start working to block and filter up to 98% of all Spam/UCE ("unsolicited commercial email") and Virus infected emails using it’s default "out-of-the-box" settings alone.
Below is an screen shot of the simple interface of the quarantine. From here you can whitelist and release any false positives. This works for the “entire” domain name at the DNS level before mail ever gets to your inbox.
