Answer 1

after using
message => utl_raw.cast_to_raw ('UPOZORNENI: Platnost trial verze produktu u zakaznika vyprší') || ReturnPocetDni || utl_raw.cast_to_raw (' dni. '),
i recieved mail containing
X-Priority: 3
Content-Type: multipart/mixed;
boundary="------------4D8C24=_23F7E4A13B2357B3"
This is a multi-part message in MIME format.
--------------4D8C24=_23F7E4A13B2357B3
Content-Type: text/plain; charset=windows-1250
Content-Transfer-Encoding: quoted-printable
