Support für Interneational Domains ("IDNA2008" specifications as RFC 5890 – 5894) Merged

Here in Germany there are more and more companies using Internet Domains containing there German company name including Umlauts (ÄÖÜ), like servus@gärtnerplatzalm.de

Domino "converts" servus@gärtnerplatzalm.de to:

=?ISO-8859-1?Q?servus=40g=E4rtnerplatzalm=2Ede?= <servus@g0xL184zrtnerplatzalm.de>

instead of the punnycode address (RFC3490)
servus@xn--grtnerplatzalm-5hb.de

We are facing issues with customers are not able to send mails to some endusers, who only having an Internetdomain with Umlaut. They are using Exchange and other communication partners are having no issues, besides of any Domino customer :-(

It would be important to be able to use extended Internet Domains containing Umlaute in mail adresses. Other mail systems can nowadays handle them correctly. The RFCs are more than 10 years old, so more and more customers are only rechable via International Domains.
