If web reputation services is experiencing poor performance,
try the following to test your web reputation settings:
-
Verify that the network connection is stable.
ScanMail monitors
its connection status to the Smart Protection Network and the Smart
Protection Server providing web reputation services. Enable the
alert "Smart Protection Server - Each time Web Reputation
service was unavailable/recovered" to receive notifications whenever ScanMail is unable
to connect to the web reputation source. If you frequently receive
this alert, it is an indication that your network connection is
not very stable.
-
Test the speed of one web reputation query
You can check the web reputation performance log to monitor
the speed of the web reputation queries. Add the line wtp_performance:1
to the registry key DebugModule. The registry key
path is as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ScanMail for Exchange\CurrentVersion
ScanMail will then generate the file wtp_performance.log in
the ScanMail debug
folder located in <ScanMail install path>\Debug.
The default debug folder path is as follows:
C:\Program Files\Trend Micro\Smex\Debug
This log will list the time it took to query each
URL (in milliseconds).

Note
You do not need to enable the ScanMail debug log
to perform this check.
