3. Select the Mail Sender Authentication section.
4. Flip on the toggle switch next to the name of the Mail Sender Authentication settings group if it is off.
5. In the DKIM Mail Sender Authentication section, do one of the following:
   • Select the check box next to the name of the Consider absence of DKIM signature as an authentication violation setting if you want Kaspersky Secure Mail Gateway to consider the absence of a DKIM signature of a message detected during DKIM authentication as a violation of the message sender's authenticity.
   • Clear the check box next to the name of the Consider absence of DKIM signature as an authentication violation setting if you do not want Kaspersky Secure Mail Gateway to consider the absence of a DKIM signature of a message detected during DKIM authentication as a violation of the message sender's authenticity.
