📢 Microsoft Enforces Stricter Email Authentication Rules
Starting May 5, 2025, Microsoft Outlook will require all high-volume senders (5,000+ emails/day) to comply with DMARC, SPF, and DKIM authentication standards. Failure to meet these requirements could result in emails being flagged as spam and eventually rejected altogether.
🔹 Why the change?
Microsoft is strengthening email security to combat phishing, spoofing, and spam. By enforcing these authentication protocols, they aim to increase trust, reduce fraud, and improve email deliverability for businesses and individuals alike.
🔹 What do you need to do?
Ensure your domain is properly authenticated with SPF, DKIM, and DMARC to stay compliant and protect your email reputation.
