SUMMARY

This article describes a hotfix that you can apply to enable the Computational Proof functionality of the Intelligent Message Filter (IMF) to work correctly. This functionality lets you obtain a list of RFC 2821 recipients from a computer that is running Microsoft Windows Server 2003.

MORE INFORMATION

Microsoft Exchange Server 2003 Service Pack 2 (SP2) includes IMF version 2. IMF version 2 uses SmartScreen technology. IMF version 2 also provides a framework to enable the Computational Proof functionality. Computational Proof reduces the chance that legitimate e-mail messages are interpreted as unsolicited commercial e-mail (UCE).

Note UCE is also known as spam.

The Computational Proof functionality requires access to a list of RFC 2821 recipients to work correctly. However, Microsoft Exchange Server 2003 does not expose the ability to obtain a list of RFC 2821 recipients.
