IDN domain website's contact form does not send email

Hello,

I have an IDN (Hindi) domain name. Everything works perfect except the contact form. Messages from contact form are not delivered. Site admin gets a failure report having following error message.

A message that you sent contained one or more recipient addresses that were
incorrectly constructed:

[email protected]: domain missing or malformed

This address has been ignored. There were no other addresses in your
message, and so no attempt at delivery was possible.

Though if I add an ASCII email address in contact form recipient then contact form messages are delivered but not to IDN domain’s email address.

Is there any workaround to overcome this issue?

Regards,

Vinod
