Many of our customers are using both MDaemon and SecurityGateway™ together for their email security and messaging needs. Both products are loaded with anti-spam, anti-spoofing, encryption & other security features, and while some features are unique to MDaemon or SecurityGateway, many are found in both products, and therefore can be disabled in MDaemon as long as they are enabled in SecurityGateway.
