Hotmail emanates abuse reports to DMARC address, erroneously assuming emails originate from its own IP RRS feed

  • Question

  • Recently I started receiving abuse reports from Hotmail, stating that:

    This is an email abuse report for an email message received from IP 40.92.255.105 on Mon, 12 Jun 2017 15:53:06 -0700. The message below did not meet the sending domain's authentication policy.

    Sample attachment is quoted below (domain name is redacted as ****). Domain has all proper SPF, DKIM and DMARC settings and passes dkimvalidator.com tests. 40.92.255.105 is NOT the domain's IP, but Hotmail's IP. Please advice on what can be done.

  • You have asked in the wrong forum. This forum is for questions and discussions about the TechNet Wiki. I believe you should ask your question in a Microsoft Answers/Community forum dedicated to Outlook messaging, such as this one:

    Search for similar questions, or click on "Participate" and select "Ask a Question". The Answers/Community forums are on a different platform, so we cannot move this question there. You will need to ask your question again. Sorry.
