XWall is a firewall to protect your Microsoft Exchange Server from viruses, spam mail and dangerous attachments.

XWall scans your incoming and outgoing messages for viruses and blocks attachments so that your users do not fill the Microsoft Exchange Server with unnecessary or dangerous files.

XWall blocks spam mail by checking incoming messages against MAPS (Mail Abuse Protection System) and it keeps a copy of each incoming and outgoing message for tracking purposes. It also writes a statistic file to give you an overview about the traffic on your Microsoft Exchange Server.
