Domain mapping - Are there any additional DNS records that must be changed to map to my own sites?

Hello,

I recently installed domain mapping. Currently the sites I am looking to map are all my own domain names. I use godaddy and I've gone ahead and fixed each of the domains to point to my dedicated IP address. However, each time I try to map the domains, I get the following alert. Is there something else that needs to be changed in the DNS records because they are my own domains and not purchased through the plugin?

Thanks, looking forward to hearing back.
