I am trying to understand how I should write my DKIM key in GoDaddy. What I wrote in the picture is my guess but I will then add my DKIM Key to sendmail and if I'm note sure this one is right I'll probably bang my head for hour in case of an error figuring out which is wrong.
This question is about the Host TXT Value part and brackets or selector conditions
let's say my domaine is goomoo.co
and my DKIM key is ABC
and I want one DKIM Key for the whole domain.
