To configure additional settings of DMARC message authentication for a rule:
In the main window of the application web interface, open the management console tree and select the Rules section.
In the list of rules, click the link with the name of the rule to open the rule for which you want to configure additional settings of DMARC message authentication.
Select the Mail Sender Authentication section.
Flip on the toggle switch next to the name of the Mail Sender Authentication settings group if it is off.
In the DMARC Mail Sender Authentication section, do one of the following:
Select the check box next to the name of the Consider DMARC authentication result as primary setting if you want Kaspersky Secure Mail Gateway to determine authentication violations based on the results of DMARC authentication.
Clear the check box next to the name of the Consider DMARC authentication result as primary setting if you do not want Kaspersky Secure Mail Gateway to determine authentication violations based on the results of DMARC authentication.
If the check box is selected, an authentication violation is determined based on the results of DMARC authentication. If the check box is cleared, the results of SPF-, DKIM- and DMARC authentication are considered to be equivalent. A violation under any of these authentication methods is considered to be an authentication violation. If violations are found for several authentication methods simultaneously, the most strict of the defined actions to take on the message is applied during SPF, DKIM or DMARC authentication violations.
