Hmm. RFC 2821 says:
2.3.5 Domain
A domain (or domain name) consists of one or more dot-separated
components. These components ("labels" in DNS terminology [22]) are
restricted for SMTP purposes to consist of a sequence of letters,
digits, and hyphens drawn from the ASCII character set [1].
[...]
This would seem to preclude accented characters presented in any way
other than IDN format, and leave it up to the MUA (or DNS resolver?) to
perform the translation.
Cheers,
John.
