I don't have problems so I'm not reaching out to anyone. Got all my DNS records setup correctly years ago.
>>Even though you do not own hotmail.fr you can still configure dkim
How you can configure DKIM for hotmail.fr is my question.
and they already have DKIM as we all hope for: https://easydmarc.com/tools/dkim-lookup?domain=hotmail.fr

Domain name and DNS records are two different things. DNS records point to a domain name. Even though you do not own hotmail.fr you can still configure dkim if you know what you are doing and have a premium account. If you are unsure how to configure dkim in hotmail then you can reach out to support here: https://support.microsoft.com/en-us/office/how-to-get-support-for-outlook-com-f5482a98-616c-4d44-b7c5-8aaaadf5c11a
This is an article that explains the problem that all mail admins should have been prepared for: https://blogs.cisco.com/security/february-1-2024-a-date-all-email-senders-should-care-about and here https://www.proofpoint.com/us/blog/email-and-cloud-threats/google-and-yahoo-set-new-email-authentication-requirements
Not many mail admins use hotmail. But for people who do, I said you need to test with tools like mx****. Hotmail already has the dns records setup for you if you use the free service and the free service does not offer dmarc or dkim signing. You have to have a premium plan or office 365 subscription as I mentioned.
WIth office 365 you can setup dkim here: https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/email-authentication-dkim-configure?view=o365-worldwide
Good luck
FYI
you're teaching someone who does mail administration for a living. I understand you try to help but you're replying to the wrong people (mail admins). Perhaps you know something that I don't. Please explain how you can configure SPF, DMARC, DKIM record for a domain that isn't yours (for example: hotmail.fr)? I'd be happy to learn something new.
The following is what I'm interested to find out so tell us how to configure DMARC and DKIM on Microsoft's domain hotmail.fr?
>> In cases of free email providers, you will need to look up how to configure dmarc and dkim settings on that providers email.
