I have a .shop domain and adding email address in the backend (user info) i get the following errors:
- ... is not a valid hostname for email address
- ... appears to be a DNS hostname but cannot match TLD against known list
- ... appears to be a local network name but local network names are not allowed
exactly the same issue as described here: https://github.com/magento/magento2/issues/4547
Is there a way to turn-off the email validation in magento 2.1?
