You will get exactly the same kind of problem as soon as you have a charset
parameter for a MIME bodypart which have a different value than the
charset/encoding we will use for a domainname.

Reason for this is that the transformation in the header:

<sender local script> -> <whatever the IDN group selects> -> <receiver
local script>

and the transformation in the body:

<sender local script> -> <whatever the email client selects as charset> ->
<receiver local script>

most certainly will produce different results in receiver local script
regardless of what the IDN group selects.

This especially in clients where the client is not "IDN aware".


And, this regardless of whether UTF-8 or ACE encoding will be selected (or
anything else).


I think John has already pointed this out a number of times...
