My domain is bankruptcylawyerbuffalo.com. I am running it through Cloudflare. I have set up SPF without problem and have added the DKIM text to the text record in the Cloudflare DNS.

When i use the tool DKINCore that you link to and enter the selector and domain I get a message that the key Record is valid. Further down the page I again enter the selector and domain and when I click "Check" a new record is generated but no confirmation of its valididty is offered. When I check back to the control panel my DKIM still shows "not-enabled".

I then went to MXtoolbox which you use in your descriptive video. I successfully recovered the DKIM record from Cloudflare. However, on the DKIM screen in Control panel there is no provision to paste any text.

Can you help?
