DKIM paste in Wordpress won't work

DKIM paste in Wordpress won't work

Hello,

I am trying to set up my DNS's in my domain (Wordpress) because lots of emails from Creator are not delivered to Hotmail accounts.

I managed to understand the SPF part, but not the DKIM part. Zoho wants me to paste a very long DKIM script in Wordpress, and Wordpress wants it as CNAME, and won't accept the script from Zoho, says it is a "non valid point to". It prefers simplier thing, see my screen shot below :


What do I do wrong ?
