Help on DMARC Error

Hi Guys, I need help with email DMARC, DKIM configuration with Cloudflare DNS
Microsoft Office365 is reporting that my domain( does not have DMARC configured, and it is not true because when I check the configured DMARC record with MXTOOBOX it reads fine here the proof
Network Tools: DNS,IP,Email

What am I missing?

Your help is much appreciated.


Hi @user6743

Firstly, then all email related DNS records needs to be unproxied, as Cloudflare is not listening on port 25, so the email traffic should not be routed through Cloudflare.

Secondly, then DKIM, DMARC and SPF records are email provider related, so you will need to ask your email provider about what content should be in these records.

Your SPF record is invalid.

As @louise2 indicated, you have proxied hostnames in your MX records, which will always cause problems.

If you are using Microsoft 365 as your email provider, your DKIM records have not been created, and your SPF and MX records do not contain the correct information.
