I am trying to register an account using certbot @api2 but facing following error in logs:
“detail”: “Error creating new account :: contact email “firstname.lastname@example.org” has invalid domain : Domain name is an ICANN TLD”,
I checked MX record and found those publicly available.
> dig +tcp +short nic.in MX
> 0 mailgw.nic.in.
How this error can be resolved as this domain has well-known email accounts which are widely used.
