As I stated in schappo.blogspot.co.uk/2017/01/chinese-email-address.html both DataMail and Google mail support Email Address Internationalization (EAI). DataMail provides a complete EAI service which includes both support and creation of Internationalized email addresses. Google Mail provides a partial EAI service, in that, it supports EAI but does not yet provide for creation of internationlized email accounts with internationalized email addresses. Thus organisations using Google Mail have an advantage over those organisations having an ASCII addresses only email service and have a head start in provision of a complete EAI service.
Given the Domain name of an organisation, the Unix host command can be used to determine the mail service provider. Here are some of the organisations using Google Mail:
