Email Spam Test not getting 10/10

I have added 2 websites in cyberpanel, and added rdns for both domains, Buth the spam score is not getting 10/10. I have attached the screenshot

My Errors:
Your message is not signed with DKIM

Where DNS are managed? Cloudflare

Any update on this?

You need to add dkim to your DNS settings and in cloudflare you need remove all " " from dkim key.
Then set rdns matching mail domain what you use set SSL for mail server.

Already remove " " from DKIM, and issue SSL for mail server.

Then add that your main mail server domain for your rdns. Don’t issue mailserver SSL for all mail domains only for one. Other mail domain go list domains and issue SSL from there.

Also screenshot your DNS settings here if you want we take look are those right.
