I have been doing some work with the IMF recently after we moved away from using Antigen internally.
One thing that was particularly irritating was allowing Outlook users to see the SCL rating a mail received.
Well now there is a better way.
“ShowSCL for Exchange 2003 application allows you to place the message SCL score to the message category, so that you can easily find, sort, filter, or group the items by the SCL value.”
