@ValidateInternetAddress([Address822]; Mailaddress ) does not work with Umlaut in domain name

We use address documents in an address database. In a field named Mailaddress we save the mailaddress for clients. In field validation we use @ValidateInternetAddress([Address822]; Mailaddress ) but this does not work with Umlaut in domain name for the mailaddress.

If we enter "info@mein-büro.de" with Umlaut, an error eccurs. If there a way to validate otherwise?
thanks for good ideas. I have testet in HCL Notes 12.2 ans HCL Notes 14 beta2 environment.

Not sure you can send and receive from such IDN domains, so if the server Can't (punycode is used for routing), I do not think Formula language can, see the doc:
