    By default, Mail Sender Authentication is disabled.

  6. If at the previous step you have enabled Mail Sender Authentication, configure general settings for all authentication types:
    • Select the Consider temporary errors (TempError) as an authentication violation check box if you want Kaspersky Secure Mail Gateway to consider temporary errors (TempError) a violation of Mail Sender Authentication.
    • Select the Consider permanent errors (PermError) as an authentication violation check box if you want Kaspersky Secure Mail Gateway to consider permanent errors (PermError) a violation of Mail Sender Authentication.
  7. Configure the following scan types:
    • DMARC authentication.
    • SPF authentication.
    • DKIM authentication.
  8. Click Save.

Mail Sender Authentication is configured. The specified settings are applied to messages that match the rule criteria.
