"LuxSci's cutting-edge email security solutions have been absolutely critical to my business. Hotmail has gone down, Yahoo has gone down, my ISP's servers have crashed ... but LuxSci has remained up. This is one of the best services I have ever used. Furthermore, they provide the finest support that I have ever received for any service, ever, for anything that I've ever purchased. It goes well beyond professional - this is a gold-plated service. I'm impressed."
