Interpreting the results from DNS lookup tools involves understanding the various types of DNS records and their configurations. For example:
SPF Record: Ensure that the record includes all the IP addresses and domains that are authorized to send emails on behalf of your domain. DKIM Record: Check that the DKIM key is correctly published in the DNS and matches the key used to sign your emails. DMARC Record: Verify that the policy is set to "none," "quarantine," or "reject" based on your preferences and that the reporting email addresses are correct.
