Understanding DMARC
Acronym References:
- DMARC (Domain-based Message Authentication, Reporting, and Conformance)
- DKIM (DomainKeys Identified Mail)
- SPF (Sender Policy Framework)
DMARC is an email authentication protocol that verifies the authenticity of the sender’s domain. It helps combat phishing, spoofing, and email fraud.
Starting February 1st 2024, if you send more than 5000 emails a day to Google or Yahoo, Google and Yahoo will require your domain to have a DMARC policy and the email you send to be DMARC validated, preferably using DKIM.
Suggested Remediation Steps:
- Confirm there is a DMARC policy visible for your domain in your DNS Records.
- Confirm your email senders are DKIM verified.
- Seek Professional Guidance: If you’re unsure about DMARC compliance, consider partnering with IT professionals or email security experts who can guide you through the process.
Conclusion
Yahoo and Google’s recent DMARC changes are a significant step forward in email security. While they may require adjustments to your email authentication processes, the benefits of a more secure email ecosystem are undeniable. By understanding and proactively adapting to these changes, your business can ensure your emails continue to reach their intended recipients while being part of a safer digital environment for all email users.
