I will appreciate if someone clarify my query. I tried to add a domian name to email service with Cname method but after several hours domain name is not verified. Every time message is occurring while doing cname lookup is records are not configured correctly. Further when I tried to add TXT record in My DNS Tab  and after that click on TXT lookUo it verified instantly. 

So I Deleted the domian from dashboard by assuming that something have not correctly done by me while adding records because your manual says atleast one hours time needed to update but TXT record updated immediately.

Now I am trying to add domain again by filing cname record & TXT record simultaneouly but different error message are coming.

So I request you to clarify if Both the method Cname & TXt should be used simultaneously or we have to use either of them while verifying domain. Further what TTL should be selected.  my DNS mangement  do not allow below  7500 seconds but your manual recommend 300 seconds.

An immediate reply shall be highly appreciated. I am really very confused about what to do next.

Thanks
