It depends on what's implementing the listserv. The UA-EAI list (and all ICANN lists to my knowledge) use GNU Mailman to implement listserv, and the short answer is that it appears not. It *also* depends on the version of Python installed on the system. There are known issues with EAIs with Python's built-in core libraries (specifically the SMTP module trips an exception). According to the documentation, Python 3.5 smtplib is supposed to support SMTPUTF8 (https://docs.python.org/3/library/smtplib.html), however, the core libraries can't properly handle a IDNA2008 domain so this may fall over in places. I haven't extensively tested but I could set up some EAI mailboxes and IDN subdomains on casadevall.pro if people want me to test it. I downloaded the source for mailman and did a quick grep and couldn't find any references to EAIs so there's probably other issues here in the Archiver and List Mananger. I'm unaware of any alternatives that support EAI. Mailman is pretty much the de facto standard Michael On 7/24/19 3:57 PM, Tan Tanaka, Dennis via UA-EAI wrote:
Hello all,
Does anyone know if listserv is UA-ready? If not, are there alternatives?
Thanks, Dennis
