John,

This may not be new, but the domain you mention is an exception. 
Actually, of the 30 or so I tried, ai was the only TLD I found with an 
associated MX record.

So, do I understand correctly that, because one obscure non-RFC 
compliant e-mail address has been out there for a decade this is enough 
of a test to guarantee, there will be no issues with the current market 
leading MUAs and MTAs (and legacy ones) ?
