I am new and in problem - mail library - sending emails using SMTP

Code:

class Contact extends Controller {



    function __construct()

    {

        //ini_set("SMTP","mail.theServer.com");

        //ini_set("smtp_port",25);

        parent::Controller();    

        $this->load->library('form_validation');

    }

    

    

    function complaints_and_suggestions()

    {

        

            //Create Email - Other Code not shown here

            

            $message = "Following has been received:\n\n";

            $message .= "First Name   : ".$this->input->post('fname')."\n";

            $message .= "Last Name    : ".$this->input->post('lname')."\n";

            $message .= "Email        : ".$this->input->post('email')."\n";

            $message .= "Contact No.  : ".$this->input->post('contact')."\n";

            

            $this->load->library('email');                

            //Send Email to Staff    

            $this->email->from('[email protected]', 'Administrator');

            $this->email->to('[email protected]');                

            $this->email->subject("Some Subject");

            $this->email->message($message);

            

            $this->email->send();

            

            $this->email->clear();

            

            //Send Email to Visitor

            $message = "Respected site visitor.\n\n";

            $message .= "Thank you for submitting your comments\n";

            

            $this->email->from('[email protected]', 'Site Administrator');

            $this->email->to($this->input->post('email'));                

            $this->email->subject("Your Comments");

            $this->email->message($message);

            $this->email->send(); 

            $this->email->print_debugger();

            

            redirect('contact/success', 'location');

        endif;

    }

}

Code:

$config['protocol'] = 'smtp';

$config['smtp_host'] = 'mail.theServer.com';

$config['smtp_user'] = '[email protected]';

$config['smtp_pass'] = 'pass';

$config['charset'] = 'iso-8859-1';

$config['wordwrap'] = TRUE;
