Outlook introduces stricter email authentication standards for domains sending over 5,000 emails daily, requiring SPF, DKIM, and DMARC compliance to enhance inbox security and reduce spoofing and spam. Non-compliance will lead to messages being routed to Junk and eventually rejected. Organizations are advised to audit their DNS records and implement transparent mailing practices. Enforcement begins in May 2025. These measures aim to protect users and improve deliverability for legitimate senders, encouraging industry-wide best practices.
