The Domain-based Authentication Details chart on the Threat tab of Dashboard displays the number of messages that failed Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting & Conformance (DMARC) authentication based on the selected mail traffic direction.
SPF, DKIM and DMARC are three email authentication systems to protect against email spoofing.
The data on this tab is displayed for incoming mail traffic only.
For a summary of the total number of email messages calculated for each category,
click the 
icon at the top-left of the Domain-based Authentication
Details chart on the Threats tab of Dashboard, and refer to the data shown in the table.
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.
