Hotmail rejecting my emails

ann3 — Fri, 20 Jun 2025 13:29:48 GMT

In the last few days, hotmail is rejecting all emails that I send to hotmail addresses. Reason is as below. (I've masked recipient and sender details.)

Below is hotmail's rejection text. The help link that is suggested is no help at all. It implies that I'm sending 5,000+ emails (?!) and that I can fix this in Outlook. I am sending single emails, generally replying to the correspondent, and am using the Mail application on a Mac.

This seems to me to be an issue a long way upstream of anything I can even begin to handle myself. Who should be fixing this? Any suggestions?

Reason: A message that you sent to the following recipient could not be delivered due to a permanent error. ** The remote server ?? responded with: ** xxx_xxx@hotmail.com ??:?? This message was created automatically by mail delivery software on the server .

Reporting-MTA: dns; avasout-peh-003 [212.159.14.19]
Received-From-MTA: dns; [192.168.1.1] [46.208.19.150]

Final-recipient: rfc822; xxx_xxx@hotmail.com
Diagnostic-Code: smtp; 550 5.7.515 Access denied, sending domain xxx.PLUS.COM doesn't meet the required authentication level. The sender's domain in the 5322.From address doesn't meet the authentication requirements defined for the sender.
