Strengthening Email Ecosystem: Outlook’s New Requirements for High‐Volume Senders
Dear Puneeth,
Greetings!
Just curios about Safe Sender List exclusion, hope if any of the recipient adding any sender into Safe sender list means , user is trusting that sender and need to receive all the communications.
So please give some more brief regarding this..

The intent behind this enforcement is to encourage stronger authentication practices across the industry, particularly for high-volume senders. While honoring safe senders ensures delivery aligned with user preferences, it may limit our ability to drive broader industry improvements in email security. High-volume senders often reach large audiences, and encouraging users to manually add them to their safe sender lists can be counterproductive, it increases the risk of spoofing and undermines long-term safety goals.
