Potentially, because it depends on how you define "the environment".

One of the things the IETF needs to do is to take the IDN base and produce
specifications on how it applies in more detail to various application
protocols. I've seen drafts on URI issues, but I don't recall any drafts on
specifics for email.

In order to get the right folks involved in the discussion it is probably
better to have it on the discuss@apps.ietf.org list, or on some smtp specific
mailing list.
