When I try to reply to email sent from WordPress.com build-in contact form the reply-to address doesn't work properly.
In the mail headers the From field is working properly and the characters are right, but the Reply-to field is not functional. UTF-8 coding is extended in reply-to field to name and address fields, but in from field it is only extended to name part of the address.
This causes email client software (Outlook 2013 or Gmail) to format reply-to address on a way that the server rejects this reply email and informs about bad recipient address format.
Is there any way around this problem?
