Included below are the instructions to configure a smarthost on Exchange 2007 and 2010. Please note these instructions are provided "as-is" as McAfee SaaS does not directly support Microsoft Exchange.  For further assistance consult the Microsoft TechNet Library.

Your smarthost address can be found on the control console in the MX Records page of the Setup tab under Email Protection. An alternate listing can be found in the Hostnames and MX Records for Email and Web Protection article. A list is also included at the bottom of this article.

2) In a single server environment, select Organization Configuration and Hub Transport. In a multi server environment, select Edge Transport.
3) Click on the Send Connectors tab.
