Send email to IDN email ID

Question

How do I send email to non-Ascii email ID, for example I have adad@ÄÖß.com as emailID and when I try to send email to this emailID using

sendTo="adad@ÄÖß.com";
MailMessage msg = new MailMessage();
msg.To.Add(sendTo); 

msg.To.Add(sendTo) throws an error saying "The specified string is not in the form required for an e-mail address.".

Did you guys face this ever? Is this possible? if yes, Any idea of how I can get this working?

Answer 2

System.Uri has a config parameter for IDN support. I'm not sure if this affects MailMessage, too, or if there is an additional parameter for it.

<configuration>
  <uri>
    <idn enabled="All" />
    <iriParsing enabled="true" />
  </uri>
</configuration>
