Understanding how our spam-filter service works is easy.  Peer-to-Peer's secure anti-spam firewall scans all incoming messages for your company to determine if they are legitimate emails or spam.  Our advanced spam blocker prohibits anything except legitimate emails to pass through the spam filter.  Your legitimate messages are sent directly to your company's email server (or your ISP).  SPAM messages are placed into your Spam-Viewer for you to review and retrieve at any time.
