Similar experience with IDN domains. Most places altogether reject them, but those which accept them, only a subset accept IDN recipient in the mail address.

The SMTPUTF8 RFC to support non-ASCII local parts is from February 2012 and thus fairly new [1]. Postfix supports it since July 2014 [2] and to the best of my knowledge Dovecot still does not yet support SMTPUTF8 for LMTP.

Personally I did not enable SMTPUTF8 support in my Postfix due to the lack of Dovecot support.
