If you do not wish to install SP2, you can still read on.
Microsoft Exchange Intelligent Message Filter is a product developed by Microsoft to help companies reduce the amount of unsolicited commercial e-mail (UCE), or spam, received by users.
Intelligent Message Filter is based on Microsoft SmartScreen Technology from Microsoft Research. By using e-mail characteristics tracked by SmartScreen technology, Intelligent Message Filter can help determine whether each incoming e-mail message is likely to be spam. Based on this likelihood, you can choose to block e-mail messages at the gateway or at the mailbox store.
Exchange Server 2003 SP2 Update Note: IMF used to be a stand-alone tool downloadable from Microsoft. Although one can still download and install it separately (here, if you insist, but you don’t need it anymore), IMF is now an integral part of Exchange Service Pack 2 (SP2). You can learn how to configure it on SP2 by reading Configure Intelligent Message Filter in Exchange 2003 SP2.
