I have a few IDN domains with dynadot. I whould like to inquire them about the following, and this might help others.
I saw on a webpage this : Using IDN domains for e-mail purposes is possible only to a very limited extent, because most of the client and server software used for e-mail is not prepared to handle IDN domains. As it is uncertain if an e-mail sent from an IDN domain will be received correctly, it is not recommended to use IDN domains for e-mail communication.In general, in e-mail addresses, special characters may only be used in the domain part under the TLD of the address (after the @ character), e.g. username@äöü-domain.de. It is not possible to use special characters in the user part of an e-mail address (prior to the @ character), e.g. jürgen@äöü-domain.de.
Thus the question :
a) How Dynadot handle emails on IDN domain ? b) can one create a sub-domain on a IDN domain ?
