This document revises RFC 5336 [RFC5336] based on the result of the Email Address Internationalization (EAI) working group's discussion. Many EAI working group members did tests and implementations to move this document to the Standards Track. Significant comments and suggestions were received from Xiaodong LEE, Nai-Wen HSU, Yangwoo KO, Yoshiro YONEYA, and other members of JET and were incorporated into the specification. Additional important comments and suggestions, and often specific text, were contributed by many members of the working group and design team. Those contributions include material from John C. Klensin, Charles Lindsey, Dave Crocker, Harald Tveit Alvestrand, Marcos Sanz, Chris Newman, Martin Duerst, Edmon Chung, Tony Finch, Kari Hurtta, Randall Gellens, Frank Ellermann, Alexey Melnikov, Pete Resnick, S. Moonesamy, Soobok Lee, Shawn Steele, Alfred Hoenes, Miguel Garcia, Magnus Westerlund, Joseph Yee, and Lars Eggert. Of course, none of the individuals are necessarily responsible for the combination of ideas represented here.

Thanks a lot to Dave Crocker for his comments and helping with ABNF refinement.
