Understanding DMARC, DKIM, and SPF

DMARC, DKIM, and SPF are essential email authentication protocols to protect against spoofing and phishing.

Steps to Resolve Issues

1. Ensure your DKIM keys are valid and added to your DNS.
2. Set up a DMARC policy with a correct reporting configuration.
3. Configure SPF to define which mail servers are authorized to send email on your behalf.
4. Regularly monitor email reports for any security issues.
