Mail Usage
The Email Protection > Mail Usage tab contains comprehensive statistics about the most actively used email addresses and address domains given for various time ranges.
From the first drop-down list, select the type of data to display, e.g., Top Senders or Top Domains. Select the desired entry, and, if an additional box is displayed, specify the respective filter argument. Additionally, using the drop-down list below, you can filter the entries by time. Always click Update to apply the filters.
On the by Domain and by Address views you can manually provide a domain or an address, respectively. Note that for specifying domains, you can use the percent sign (%) as a wildcard. By placing a percent sign at the end of your keyword, you are telling Sophos UTM to look for exact matches or sub-sets. Note that the filter field is case-sensitive.
On the Top Addresses and Top Domains views, if you click an address or a domain in the result table, it will automatically be used as a filter for the Top Addresses by Domain or Top Peers by Address view.
By default, 20 entries per page are displayed. If there are more entries, you can jump forward and backward using the Forward and Backward icons, respectively. In the Number of rows drop-down list, you can increase the number of entries displayed per page.
You can sort all data by clicking the table column headers.
You can download the data in PDF or Excel format by clicking one of the corresponding icons in the top right corner of the tab. The report is generated from the current view you have selected. Additionally, by clicking the Pie Chart icon—if present—you can get a pie chart displayed above the table.
