Not entirely surprising. It took a while for IDNA 2008 to get implemented in libraries and those libraries to get deployed. Now it will take a while for applications using those libraries to reach users. Bleeding-edge Postfix may require a bleeding-edge base platform to support the latest features. Platforms that are optimized for stability may lack the necessary support. -- Viktor.
