Microsoft's business message server will have the anti-phishing Sender ID technology added in an update later this year.
Exchange Server 2003 Service Pack 2, due near the end of the year, will feature the first implementation of the e-mail authentication technology.
The current version of Exchange Server 2003 has filtering technology called Intelligent Message Filter which analyses messages and determines the likelihood of them being spam.
The Sender ID Framework, developed by Microsoft and a group of partners, is a protocol designed to verify that an e-mail message originated from the domain in its address. Sender ID attempts to curb the problem of spoofing, in which an e-mail message's real domain is masked with another domain.
Scammers use spoofing to make recipients believe an e-mail message came from a legitimate source, such as their bank or a store. Then they try to trick recipients into providing them with sensitive information, such as account numbers, passwords and Social Security numbers, by replying to the e-mail or by clicking over from the message to a legitimate-looking website and entering the information there.
Another enhancement coming in Exchange Server 2003 Service Pack 2 is a simplification of the way IT administrators grant a new employee access to an existing public folder. Until now, that process has been time-consuming, but it will automated through wizards in the new version. Public folders can be created in Exchange Server 2003 to store messages, contacts, calendars and documents, so that they can be access by a group of users.
Exchange Server 2003 Service Pack 2 will also increase storage capacity from 16GB to 75GB.
