Microsoft Steps Up Pressure To Adopt Spam-Fighting System

NEW YORK - Microsoft Corp. is stepping up the pressure on e-mail senders to adopt its "Sender ID" spam-fighting technology despite problems that could send up to 10 percent 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.
Sender ID seeks to cut down on junk e-mail by making it difficult for spammers to forge e-mail headers and addresses, a common technique for hiding their origins.
The system calls for Internet service providers, companies and other domain name holders to submit lists of their mail servers' unique numeric addresses. On the receiving end, software polls a database to verify that a message was actually processed by one of those servers.
