Microsoft Adds Sender ID Anti-Spoofing Protocol To Exchange 2003 SP2

"When it launches later this year, Exchange Server 2003 Service Pack 2 (SP2) will support Sender ID, Microsoft's sender authentication scheme, the Redmond, Wash.-based developer said. The addition of Sender ID to Exchange 2003 SP2 will be the first time Microsoft's mail server includes an authentication technology, although Microsoft has been pushing the scheme for more than a year. It's also been using Sender ID on its free Hotmail e-mail service, where it claimed the authentication has reduced spam and phishing scams, although it hasn't released hard numbers."
