Today, at the third annual Authentication and Online Trust Summit, Microsoft Corp. published results culminating from a two-year-long study on the effectiveness of Sender ID Framework e-mail authentication in helping counter deceptive e-mail. With Windows Live� Hotmail� alone detecting over 3.8 billion deceptive messages daily, Sender ID is helping provide real results as a cost-effective solution. Sender ID has enjoyed a threefold increase in adoption, accelerating to 8 million domains worldwide in just under a year.* This technology is helping to realize the promise established by the industry and government agencies to improve trust and confidence in e-mail communications for consumers and marketers alike.

�Spam and phishing attacks continue to undermine user productivity, trust and online confidence. The business value of Sender ID is now providing tangible benefits,� said Ryan Hamlin, general manager of the Technology Care and Safety Group at Microsoft. �Widespread adoption of the Sender ID Framework, continued collaboration with industry, businesses and governments, and a commitment to user education are all promising steps toward protecting the inbox. To help stem this tide of deceptive e-mail, businesses must implement today to protect their brand, their customers and their employees.�
