Using IDNs in email addresses
You can use the IDN representation of a domain name in email addresses if your browser is IDN-compatible.
Important: If your application is not IDN-compliant, you must use the ASCII-encoded representation of the domain name to access the domain. To view the ASCII-encoded representation, click the link show text name next to the IDN.
When you specify the email address of the Site Administrator while creating a domain <idn_domain>.com, you may enter the email address siteadmin@<idn_domain>.com in the Email Contact field.
To specify the email address for the Site Administrator admin1 of the domain fargbolaget.nu, type the email address as follows:
admin1@färgbolaget.nu
However, if your browser is not IDN-compatible, you must use the ASCII-encoded representation of the domain in the email address as follows: user@<ascii_encoded_domain>.com.
To specify the email address for the Site Administrator admin1 of the domain fargbolaget.nu using its ASCII-encoded representation xn--frgbolaget-q5a.nu, type the email address as follows:
admin1@xn--frgbolaget-q5a.nu
