Hi,
This is the C# code to send emails in HTML format.
MailAddress SendFrom = new MailAddress(txtFrom.Text);
MailAddress SendTo = new MailAddress(txtTo.Text);
MailMessage MyMessage = new MailMessage(SendFrom, SendTo);
MyMessage.Subject = "Subject here";
MyMessage.IsBodyHtml = true;
MyMessage.Priority = MailPriority.Normal;
MyMessage.Body = "Some Html Body here";
SmtpClient emailClient = new SmtpClient();
emailClient.UseDefaultCredentials = true;
emailClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
emailClient.Host = "localhost";
emailClient.Send(MyMessage);

You need to authenticate on the server.
If you MailObj is a SmtpClientyou are missing this:
MailObj.Credentials = new NetworkCredential("username", "password");
