Microsoft Adopts Spam-Fighting System

"Microsoft Corp is stepping up the pressure on email senders to adopt its Sender ID spam-fighting technology despite problems that could send up to 10% of legitimate messages to junk folders. By the end of the year, Microsoft's Hotmail and MSN services will get more aggressive at rejecting mail sent through companies or service providers that do not register their domain names with the Sender ID system."
