Microsoft Pushes Anti-Spam Technology
Microsoft Corp. is stepping up the pressure on e-mail senders to adopt its Sender ID spam-fighting technology despite problems that could send as many as 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.
Sender ID seeks to cut down on junk e-mail by making it difficult for spammers to forge e-mail headers and addresses.
The system calls for Internet service providers, companies and other domain name holders to submit lists of their mail servers’ unique numeric addresses.
