IDN domain website's contact form does not send email


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?
