Your DMARC policy is stored on your server and determines what happens to any emails sent from your domain that fail authentication.
Whether or not your email will end up in your customer’s email inbox is determined by the DMARC (Domain-based Message Authentication, Reporting, and Conformance) policy. Your DMARC policy is stored on your server and determines what happens to any emails sent from your domain that fail authentication.
The recipient’s email server performs authentication with the SPF record and DKIM key and if either one of the two passes, the email gets delivered. If both SPF and DKIM authentication fail, the DMARC policy determines what to do with the email.
The following are some of the available policies:
Quarantinepolicy means that if the email fails authentication, it will be directed to recipient’s spam folder.Rejectpolicy means that if the email fails authentication, it will not get delivered.Nonepolicy means that neither of the above policies is in place and the email will get delivered. This is also known asRelaxedpolicy.
To check your DMARC record configuration and policy, you can use a tool like MXToolBox or something similar.
Tip
If your DMARC policy is set to either quarantine or reject, set up a custom mailing domain to make sure emails sent from Sufio are delivered correctly.
To verify you have correctly set up your SPF, DKIM and DMARC records, use a tool such as Learn and Test DMARC, mail-tester or similar that let you verify that an email you send from your domain passes all the checks.
