Fix Content-Type in emails

Fix Content-Type in emails

I have noticed if I view the original source of my incoming emails, I see the following
------=_Part_1410627_147770577.1522488015368
Content-Type: text/plain;charset="UTF-8"
Content-Transfer-Encoding: quoted-printable
However the text below is clearly in HTML formatting ..

Below that section I see the following :
------=_Part_1410627_147770577.1522488015368
Content-Type: text/html;charset="UTF-8"
Content-Transfer-Encoding: quoted-printable
Is the same thing as above also in HTML formatting.

Here is a PB of what I see. https://pastebin.com/XiacPX3a

The content under plain text needs to be either in plain text or removed if sending via HTML, and vise versa.
