[UA-EAI] listserv question

[Michael Casadevall]

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
