Hi,

I am trying to register a domain www.topassessoria.com.br in zohomail, I have already done the CNAME, TXT and HTML settings and when I click on check I get the message: "This Operation has been restricted. Please contact support@zohomail.com for further details"

What is the reason for this message since all DNS settings are correct?

Regards,
Edjames Oliveira
