Exchange Server RFC and standards complianceArticle ID: 262986 - View products that this article applies to. This article was previously published under Q262986 SUMMARY The information contained in this article represents the
current view of Microsoft Corporation on the issues discussed as of the date of
publication. Because Microsoft must respond to changing market conditions, it
should not be interpreted to be a commitment on the part of Microsoft, and
Microsoft cannot guarantee the accuracy of any information that is presented in
this article after the date of publication. This article is for informational purposes only. MICROSOFT MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE INFORMATION IN THIS DOCUMENT. This article is intended to be a reference for the Requests for Comments (RFC) and other standards that are supported in Microsoft Exchange Server 5.5, Microsoft Exchange 2000 Server, and Microsoft Exchange Server 2003. While every effort has been made to verify this information, omission of an RFC from this list does not necessarily mean that Exchange does not at least partially comply with the RFC. RFCs are guidelines, but often contain two types of information: required and optional. Microsoft and other vendors may or may not choose to implement optional requirements or may interpret portions of RFCs differently. However, if you do have an issue where you feel that Exchange is not compliant with a particular RFC and this is causing a problem, please open a support incident with Microsoft Product Support Services.
