Last week I finished the port of Debian-style shared libraries and
dynamicmaps.cf much of which I did during my vacation in Europe.

I have looked at parts of the patch in my copious time.
First, Postfix behavior must not change unless mail is flagged as
EAI, regardless of whether it contains 8-bit headers or envelopes.
Thus, the SMTP client, cleanup daemon, and other daemon programs
MUST NOT engage into any EAI-related stuff unless a message is
flagged as EAI-enabled. I will add a guard around that code.
As for EAI auto-detection in Postfix the sendmail command, I will
make that configurable if it isn't already.
Have you given any thought of what happens when a company installs
Postfix-EAI on the perimeter, and wants to forward the mail to their
internal systems that may or may not have EAI support?
Postfix has already passed 8-bit headers and envelopes for 15 years
and we can't suddenly stop doing that when a down-stream system
doesn't announce SMTPUTF8.
I haven't looked yet at the interface with database systems.
At this interface we can expect characterset issues.
