Microsoft Corp. Wednesday disclosed that it will not ship—as a separate product—its Exchange Edge Services, a set of e-mail security and anti-spam enhancements for Exchange Server. In May, Microsoft said it would roll out Exchange Edge Services in 2005. The package was expected to provide support for identification standards, such as SPF (Sender Policy Framework), as well as other tools and techniques designed to stop spam, including IP Safelist, or presolved puzzle validity.
