WKD for separate email hosting?

I don't understand your question?  Running several domains on one IP
address is standard deployment.  SNI works just fine and we do not need
to care about outdated OSes which are not able to handle them.  All TLS
libraries do SNI.

I doubt that anyone will ever be able to get the BS of internationalized
mail addresses and domains right.  That is such a large can of worms
that you better don't open it without asbestos.

Fortunately we can step this aside in the protocol specs.  OpenPGP
requires UTF-8 and thus the protocol uses only UTF-8 and leaves all
IDNing to the MUA.

ps.
I stripped the subject which was modified by strange behaving MUAs to
inserts arbitrary strings like "AW:" instead of the the de-facto standard
"re:" and "was:".
