yep, this was a typo; I did not have the line for cut&paste (because it
gets stripped out), but I checked the original source file and it is
there;

No, should we?
I inserted now in addition:
MIME-Version: 1.0
In this case the mail arrives fine and the header gets re-written as:
Content-Type: text/plain;
charset="utf-8"
MIME-Version: 1.0
Note: the utf-8 is now in small letters and the line splitted into two;
i.e. the MTA rewrote the Content-Type header line;
Does this mean that we must use in addition "MIME-Version: 1.0" header?
Thanks
