Hello everyone, I tell you the following:
We need your help because the DNS server fails to resolve 8.8.8.8 records turboitalia.tech domain, which is causing problems with our email service.

The following information is collected:
  - Detection date: from the 26th of June, 2017.
  - Location: Italy
  - Platform: MDaemon mail server, user computers, etc.
  - Issue: Mail servers that use Google's public DNS servers are not able to validate our A, MX, or TXT records, so they reject our emails.
  - This problem is permanent.


Thank you in advance for your help.
Best regards,
Welcome Italia

The 'turboitalia.tech' zone has a DNSSEC misconfiguration.
The parent zone 'tech' has a DS record for 'turboitalia'
but the 'turboitalia.tech' zone has no DNSKEY record.

To fix this, contact your registrar 'Tucows.com Co.' and have them
remove the DS record for 'turboitalia.tech'
in the 'tech' zone.

'turboitalia.tech' is in 'turboitalia.tech' zone under .TECH
'turboitalia.tech' is failing DNSSEC validation, and has
2 nameservers in 'welcomeitalia.it' (all are failing validation)

'turboitalia.tech' is registered through 'Tucows.com Co.'
