   This may be the path of least resistance. I'm still trying to think through hat would happen if a registry returns an internationalized email address to a registrar that doesn't expect one. This could happen after a domain transfer, for example. Is this a problem? If not, maybe we could just get by without any other protocol changes or extensions.



   From my point of view, if the registry has implemented EAI support, all the registrars will have to do it. They should deal with the clients with such emails _somehow_.

   E.g., they hardly can reject the transfer relying on this reason.



   [SAH] I’m not talking about rejecting a transfer. I’m talking about what a registrar that does not support EAI would/should do if it is the receiving registrar of a domain that includes contacts using internationalized email addresses and those addresses aren’t supported by the registrar. How should this work?
