I solved the original problem completely by chance while experimenting
with SMTPUTF8. I did re-write smtpmail.el as below:

<quote: patch smtpmail.el in emacs-25 branch>
diff --git a/lisp/mail/smtpmail.el b/lisp/mail/smtpmail.el
index 9dc4ace050c..3efbcc27d46 100644

+++ b/lisp/mail/smtpmail.el

                         "")
                     "")))
              (smtpmail-send-command
-              process (format "MAIL FROM:<%s>%s%s"
-                              envelope-from size-part body-part))
+              process (format "MAIL FROM:<%s>%s%s %s"
+                              envelope-from size-part body-part "SMTPUTF8"))
              (cond
               ((smtpmail-ok-p (setq result (smtpmail-read-response process)))
                ;; Success.
</quote>

And i attached tested 8bit email (with SMTPUTF8):
