Zoho doesn't verify MX records on a subdomain
I created an account in Zoho using a subdomain of my main domain so I can use Zoho accounts such as "
user@subd.maindomain.com"
Everything seems ok, except for the MX records. I already created those MX records:
10
mx.zoho.com
20
mx2.zoho.com
I did this like an hour ago and Zoho still doesn't find them. I even used MXTOOLBOX to check and I can see the records, but Zoho doesn't.
