Re: Will case of non-ascii character be preserved by IDNA?

Similar in this case; you invoke IDNA on the IDN and then put the
output in the header.

MÜNCHEN.NET => xn--mnchen-3ya.NET

Thus, you will send:

To: MARIA <MARIA(_at_)xn--mnchen-3ya(_dot_)NET>

Which is translated, by the receiver, into:

To: Maria <maria(_at_)münchen(_dot_)NET>

That doesn't seem right. How did the local-part maria come to be in lower
case?
