TXT verification fails

TXT verification fails

Hello
 
I just verified the domain ownership in order to use Zoho as my e-mail provider for the domain. The CNAME method does not work because my DNS provider appends the domain name as a suffix to any CNAME entries, so I had to use the TXT method. At first I tried to use the @ name for the TXT record, and it did not work. I could access the TXT record from an external DNS query service (mxtoolbox), but it did not verify. I used the @ because I could not leave the name field blank. So then it occured to me to use the domain name as the name of the record, since there was already one configured like that for the SPF, and voila, my DNS provider uses that syntax for configuring blank record names so it worked. But the fact that the @ record name does not work worries me. Is the verification service querying the @.domainname.com TXT record correctly?
 
As I said, my problem is solved, I just wanted to let you know.
 
Thank you.
