SP1 includes updated tools for managing upgrades from Exchange 5.5. The tools are designed to ease the process of removing remote Exchange 5.5 servers in support of migrating mailboxes to Exchange 2003 at companies with multiple sites. There is also support for snapshot backup and improved deployment and troubleshooting tools in this release. Next year, Microsoft plans to introduce Exchange Edge Services, which will include support for CallerID/SPF as well as other tools and techniques designed to stop spam, including IP safelist, presolved puzzle validitya technology Bill Gates first talked about last year that would require sending servers to solve complex computational puzzles for each e-mail they send out.Microsoft also will look to provide technology that detects spam based on e-mail traffic analysis, according to Kim Akers, senior director of Microsofts Exchange group, though Akers said how Exchange would support those technologies has yet to be determined exactly."These are technologies we have in development," Akers said. "Were taking the basic concept and figuring out how to implement them." Beyond 2005, Microsoft will look to improve e-mail life-cycle management in Exchange, such as allowing customers to set a policy that automatically deletes or archives e-mails past a certain date, Akers said. Other technologies on the drawing board call for Exchange to support Longhorn server, a 64-bit architecture, Web services interfaces and WebParts, the Web Services Security Common Engineering Criteria. Akers said Microsoft has yet to determine when these technologies would be supported. Microsoft is also dropping the Kodiak codename from its next-generation Exchange release, which was to have been based on a future version of SQL, codenamed Yukon. Akers said many of the features intended for the Kodiak release will be a part of future Exchange 2003 service packs instead. "Because of changing customer needs, were bringing more functionality earlier to customers," she said. "So, were not carrying forward the Kodiak name."´ Check out eWEEK.coms Windows Center at http://windows.eweek.com for Microsoft and Windows news, views and analysis.
