Establishing custom MAIL FROM Subdomain TXT and MX records in go DoDaddy

Question

I am pretty new to SES, and DNS management as well I suppose so bear with me. I connected my main domain "example.com" to SES and verified it. Now I would like to create a custom MAIL FROM domain for it "mail.example.com". I created a CNAME record in godaddy to create the subdomain. 
"	cname	mail	example.com.	1/2 Hour" 
Now I need to add an MX record and TXT record for the subdomain, and here is where the problem is:
(This is in the DNS manager for "example.com") 
mx	mail.example.com	feedback-smtp.us-west-2.amazonses.com. (Priority: 10)	1 Hour 
"txt	mail.example.com	"v=spf1 include:amazonses.com ~all"	1 Hour"
Above are the records I have in GoDaddy, but SES is stuck on pending... I've waited out the 72 hours 3 times now, I am not sure how much more time I can waste on this, has anyone else been in the same situation? Did you find a way out?

Answer

Afraid DNS Does not work like this.

To have a subdomain, you require NS records for a SubDomain not a CNAME. Then you need a DNS Server thats authoritive for the subdomain. It could be the same name server that is auth for your top domain depending on its configuration.

Once DNS is setup for your Subdomain, then you can create a MX record in your sub domain...

You could try creating NS records for your Subdomain to point back to the same name servers you have for the top level domain and then create your MX record in the same name server ensuring your MX record is for mail.example.com

EG
NS Records for example.com would point to dnsserver1.godaddycom
NS Records for mail.example.com would point to dnsserver1.godaddycom
