Some email clients will show the text part before the HTML part of the email. Thus when sending an email with Nettalk, is there any way, not create the text part of the email body. I have called the SetRequiredMessageSize method with text size parameter equal to zero and not assigned anything to the MessageText property. But the email generated, still has text message part before the HTML part as shown below:
----=_NextPart_001_d20120215t225629.74c3r60669
Content-Type: text/plain;
charset=us-ascii
Content-Transfer-Encoding: 7bit
----=_NextPart_001_d20120215t225629.74c3r60669
Content-Type: text/html;
charset=us-ascii
Content-Transfer-Encoding: quoted-printable
<HTML stuff.....
