The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the msExchServerBindingsFiltering property of a Simple Mail Transfer Protocol (SMTP) virtual server object indicates that the Intelligent Message Filter is enabled for an SMTP virtual server instance.

The Exchange Server Analyzer also queries Active Directory to determine whether the msExchUceEnabled is enabled at the Global Settings level.

The Exchange Server Analyzer displays a warning if the following conditions are true:

This warning indicates that the Exchange Server 2003 Service Pack 2 (SP2) version of Intelligent Message Filter is effectively enabled. Having the SP2 version of Intelligent Message Filter enabled is not generally an issue unless you are troubleshooting mail flow issues involving this particular server. If that is the case, you may want to verify the filter configuration or temporarily disable the Intelligent Message Filter to determine whether it is incorrectly blocking legitimate mail.

To Disable Intelligent Message Filter
  1. Click Start, point to All Programs, point to Microsoft Exchange, and then click System Manager.

  2. In Exchange System Manager, expand Servers, expand Server name, expand Protocols, and then expand SMTP.

  3. In SMTP Virtual Server Properties, on the General tab, click Advanced.

  4. Select the IP address for which you want to disable the Intelligent Message Filter and then click Edit.

  5. In Identification, clear the Apply Intelligent Message Filter.

  6. If you have multiple virtual servers, repeat Steps 3 through 6 for each virtual server on which you want to disable the Intelligent Message Filter.
