	// 1) Join Mandrill at http://mandrill.com/
	// 2) Download PHPMailer from https://github.com/PHPMailer/PHPMailer
	// Adapted example from: shared/PHPMailer-master/examples/mailing_list.phps
	require_once 'shared/PHPMailer-master/class.phpmailer.php';
	require_once 'shared/PHPMailer-master/class.smtp.php';

	$message = "This is a test message prepared on: " . date( 'r' ) . " from " . $_SERVER['HTTP_HOST'] . ' ' . $_SERVER['REMOTE_ADDR'];

	$mail = new PHPMailer;
	$mail->addAddress( 'example_recipient@example.com', 'Example Name' );
	$mail->Subject = "Testing Mandril: " . date('Y-m-d');
	$mail->msgHTML($message);
	$mail->Username = 'youremail@example.com';
	$mail->Password = 'your_mandrill_api_key';
	$mail->Host = 'smtp.mandrillapp.com';
	$mail->isSMTP();
	$mail->SMTPAuth = true;
	$mail->SMTPKeepAlive = true; // SMTP connection will not close after each email sent, reduces SMTP overhead
	$mail->Port = 587;
	
	$mail->setFrom( 'mailer@' . $_SERVER['HTTP_HOST'], $_SERVER['HTTP_HOST'] );
	
	//msgHTML also sets AltBody, but if you want a custom one, set it afterwards
	$mail->AltBody = 'To view the message, please use an HTML compatible email viewer!';

	$sent_status = $mail->send() ? 1 : 0;

	$result = "Send status: " . $sent_status;
	
	if ( ! $sent_status ) {
		$result .= " Error: " . $mail->ErrorInfo;
	}
	
	echo $result;
