Smart host is set on SMTP virtual server

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the msExchSmtpSmartHost attribute has been configured on a particular SMTP virtual server. If the Exchange Server Analyzer finds that the msExchSmtpSmartHost attribute is configured, the Exchange Server Analyzer displays a warning.

It is not a best practice to configure a smart host on an SMTP virtual server. Instead, you should create an SMTP connector and configure the smart host setting there.

In Exchange Server 2003, use Internet Mail Wizard to configure Internet mail delivery. For more information, in the Exchange Server Transport and Routing Guide, see "How to Use Internet Mail Wizard" (
