The Microsoft® Exchange Server Analyzer Tool reads the following property in the Microsoft Internet Information Services (IIS) metabase to determine the current configuration settings for Trend Micro ScanMail for Microsoft Exchange:
The Exchange Server Analyzer also queries the Active Directory® directory service to determine the value for the serverRole attribute of the Exchange server object. A value of 1 for the serverRole attribute indicates that the Exchange server has been configured as a front-end server. A value of 0 indicates that the Exchange server is not configured as a front-end server.
The Exchange Server Analyzer also queries the Win32_OperatingSystem Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the OSProductSuite key for the Exchange server. This query is performed to determine the specific operating system that is running on the Exchange server.
The Exchange Server Analyzer also reads the following registry value to determine the version of ScanMail for Exchange that is running on the Exchange server:
HKEY_LOCAL_MACHINE\Software\TrendMicro\ScanMail for Exchange\CurrentVersion\Version
If the value data for the Version value starts with 7, it indicates that ScanMail for Microsoft Exchange Version: 7 is installed.
Finally, the Exchange Server Analyzer queries Active Directory to determine the number of objects that have a homeMDBBL attribute configured. Objects that have the homeMDBBL attribute configured are mailbox-enabled objects. Therefore, the count of the number of objects that have homeMDBBL configured is the number of mailboxes that exist.
The Exchange Server Analyzer displays a best practice message if the following conditions are true:

- The Exchange server contains more than 20 mailboxes.

Trend Micro recommends that users of ScanMail for Microsoft Exchange Version: 7 disable SMTP scanning that uses the ScanMail management console on mailbox servers if there are separate dedicated gateway or bridgehead servers. For best performance and security, Trend Micro recommends that SMTP scanning be enabled on gateway bridgehead servers instead of on mailbox servers.
