HTML Email not displaying as HTML but as text

[eluser]Dr. Seuss[/eluser]
Certainly, my apologies.

I am using CI 1.7.1.

Here is the complete function:

Code:

function _authmail($eml, $strSubject,$strMessage ){
$this->load->library('email');

// $this->email->set_newline("\r\n");
$this->email->from('[email protected]', 'Website');
$this->email->to($eml);
$this->email->subject($strSubject);
$this->email->message($strMessage);
$this->email->send();

// echo $this->email->print_debugger();

}

...and the config file, "Email.php":

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/*
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
*/

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.gmail.com';
$config['smtp_port'] = 465;
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'password';
$config['smtp_timeout'] = 30;
$config['email']['mailtype']  = 'html';
$config['email']['charset']   = 'utf-8';
$config['wordwrap'] = TRUE;
$config['newline'] = "\r\n";
$config['crlf'] = "\r\n";

And the resulting email:

&lt;/body&gt;&lt;/html>

I note that the line "Content-Type: text/plain; charset=utf-8" and I don't know if that is the problem or not (i.e. my '$config['email']['mailtype'] = 'html'" is not having intended effect).

Thanks for the scrutiny.
