Microsoft Scrubs Security Component for Exchange

Posted on: Friday, 21 January 2005, 03:00 CST

Microsoft has shelved a new security component for Exchange Server 2003. Instead, it will add its piece parts to a service pack and the next upgrade of the server.

Exchange Edge Services, first introduced in February 2004, is a message transfer agent (MTA) that can run at the edge of a network to provide customers with anti-spam, anti-virus and other messaging hygiene and policy-based features. Edge Services was intended to replace the current message transfer agent in Exchange, which has a dependency on Microsoft's Internet Information Server and Active Directory. The configuration can lead to open ports on the edge of networks that pose security risks.

Edge Services was to provide routing features and serve as a hub to plug in third-party e-mail security products from the likes of partners Network Associates, Sybari, Symantec and Trend Micro. It was also designed as a small cog in Microsoft's Dynamic Systems Initiative, a common management platform for Windows servers and desktops.

In May 2004, Microsoft said it would ship Edge Services in early 2005, but in November 2004, the company hinted that the date was in doubt. In late December, Microsoft confirmed that Edge Services would not ship as a separate product, and that some of its features would be integrated into Exchange 2003 Service Pack 2, due in the second half of this year,and the next release of Exchange. A ship date for the next version of Exchange has not been announced. Last year Microsoft removed the long-awaited Kodiak release from its road map.

Edge Services also featured support for the SenderlD framework, a sender authentication mechanism that was on track for standardization but crumbled late last year within the Internet Engineering Task Force. Problems with SenderlD, which is now being revised, may have had something to do with the delay of Edge Services, analysts say

"If Microsoft could not release Edge Services with some sort of authentication system, then that would have [eliminated] one of the key reasons to buying Edge Services," says Peter Pawlak, an analyst with independent research firm Directions on Microsoft."! think Microsoft realized that just crating competitive products to other [MTAs] wasn't going to sell any more licenses."

On top of that, Microsoft already had anti-spam features in the form of its Intelligent Message Filter, an anti-spam tool released in Exchange 2003 Service Pack 1. The second version was slated for release in Edge Services.

A Microsoft spokeswoman says support for the SenderID framework will be included in Exchange 2003 Service Pack 2 and that message- policy technology from Edge Services will be included in the next release of Exchange.

"Customers said they needed help meeting regulatory compliance requirements, and that required additional development time," the spokeswoman says.'That placed the delivery date of Edge Services close to the release date of the next version of Exchange Server. In its current form, Edge Services was not going to meet the needs of customers."

While Microsoft is now without a formal road map for Exchange, the company says it is working on enhancing calendaring features, e- mail life-cycle management, mobility improvements, Longhorn server and 64-bit support, and integration with Web services.

Microsoft is working hard to get users to migrate from older platforms. Late last year, the company extended fee-based custom support to users of Exchange 5.5 in an effort to support those users while they migrate.

The Radicati Group forecasts that by year-end

Exchange 2003 will have 49.4 million users; Exchange 2000,47.8 million Exchange 5.5,31.9 million users.
