Yes you are correct, in header there is:
Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable
In message body i dont have any other non-ascii character. It looks like Kopano webmail set it by default and im not able to override it.
Anyway, the fix mentioned by you work. Thank you.
