MSN Postmaster Services Launches

Microsoft on Tuesday officially launched MSN Postmaster Services, which provides tools and information to ISPs on how they can work with Microsoft's e-mail filtering to ensure their messages reach Hotmail customers. ISPs can also review complaint reports and track e-mail sent to MSN that has been tagged as junk.

The service launched in early beta last year and is part of a number initiatives by Microsoft to reduce spam. The Redmond company on Tuesday also touted the success of the Sender ID framework, which verifies the domain an e-mail claims to originate from. MSN Postmaster Services is completely free and is currently available in English with other languages forthcoming.
