Emails sent from my own domain not reaching Cloudflare servers

What is the name of the domain?

What is the issue you’re encountering

I have set up Cloudflare to route my Emails. Inbound Emails are fine except for Emails sent from my own domain (I am using my own server to send Emails, just using Cloudflare to route inbound Emails)

What steps have you taken to resolve the issue?

I have tried sending Emails from my own domain to Gmail, Yahoo, Outlook, other desinations and they were received just fine. It is only when I send Emails to other maiboxes on my domain (which I already have Email routing set up for) that the Emails are not received. I do not see any bouncebacks either.

Just tried sending an Email to AboutMyEmail and this is what I got. I see that DKIM and ReverseDNS are not set property. Could that be why? But it works fine for outbound Emails to Gmail/Yahoo/Outlook.
