ScanMail for Domino 3.0 gets update from TMCM 5.0

By default your SMD will get the update from Trend Micro ActiveUpdate in the Internet. However, you can specify other Internet update source, namely TMCM.
key in "http:///TVCSDownload/activeupdate"
as the Internet update source.

By default also, your SMD will try to do secure update by means of going through https. So most likely that your update will fail if your URL for TMCM is http based. So make sure you add in the following:

Option I. Use the following command inside the server console:
set conf DisableSecureUpdate=1
The server does not need to restart when this option is used.

Option II. Follow these steps:
1. Open the notes.ini file.
2. Add the DisableSecureUpdate=1 entry as another line inside the notes.ini file. Make sure the last line of file is empty.
3. Save the file and restart the Domino server service.

Monitor the success of updates from the Domino server console.

Hope it helps.
