Introduction to Outlooks New DMARC Email Authentication Requirements
Microsoft Outlook has just announced new email authentication requirements that will take effect in April, 2025.
Domains without SPF, DKIM, and a properly aligned DMARC policy will have their emails sent to junk or rejected entirely.
Impact on High-Volume Email Senders
If your domain sends over 5,000 emails daily without proper authentication, critical communications like transactional emails, client messages, reports, and login details may soon stop reaching inboxes.
This can directly affect your business’s bottom line.
What is DMARC – Domain-Based Message Authentication, Reporting, and Conformance
DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication, policy, and reporting protocol.
It uses SPF and DKIM to verify that an email’s sender is authorized to use the domain in the “From” address.
DMARC provides reports to domain owners about which email servers are authenticating their emails, helping identify potential issues or malicious activity.
