The Blocked Message Details chart on the Threats tab of Dashboard displays the number of messages blocked for different reasons.
Select a time period by Date, Week, Month, or Last 12 months to show data for the selected time period.
The specified time period only affects the data shown on this chart and its corresponding thumbnail chart on the Threats tab. Changing these selections does not affect other charts.
