sending mails with codeigniter

Question

i have a form where the users will be able to send their messages to different mail ids. The form has fields like from, to, subject etc. the users will give their mail id in the 'from' filed and the receiver's mail id in the 'to' fields. the problem is i'm not being able to send mail though i think my code is ok. Does CodeIgniter allow to send emails in this way??

Controller

class Email_send extends CI_Controller {   

    function Email_send()
    {
        parent::__construct();
        $this->load->library('email');
        $this->load->helper('url');
        $this->load->helper('form');
    }

    function index()
    { 
        $config = Array(
            'protocol' => 'smtp',
            'smtp_host' => 'ssl://smtp.googlemail.com',
            'smtp_port' => 465,
            'subject'  => $this->input->post('subject'),
            'message'  => $this->input->post('message'),
            'from'    => $this->input->post('from'),
            'to'  => $this->input->post('to'),
        );

        $this->load->library('email', $config);
        $this->email->set_newline("\r\n");

        $this->email->initialize($config);

        $this->email->from($config['subject']);
        $this->email->to($config['to']); 

        $this->email->subject($config['from']);
        $this->email->message($config['message']);  

        if($this->email->send())
        {
            $this->load->view('success_em');
        }

        else
        {
            show_error($this->email->print_debugger());
        }
    }
}

View

        echo form_open('Email_send', $attributes); ?>

<p>
        <label for="from">Your mail ID <span class="required">*</span></label>

Answer 1

I don't think you need to add subject, message, from, to in the config object your passing to init the email class.

Try removing these and include the SMTP authentication keys as Hatem suggested.

E.g.

$config = Array(
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.googlemail.com',
    'smtp_port' => 465,
    'smtp_user' => 'user@gmail.com';
    'smtp_pass' => 'yourpassword';  
);

Answer 2

You need to authenticate first. You miss these two parameters:

$config['smtp_user'] = "user@gmail.com";
$config['smtp_pass'] = 'yourpassword';

Add them beside other configurations.

Answer 3

You need to authenticate first. You miss these two parameters:

$config['smtp_user'] = "user@gmail.com";
$config['smtp_pass'] = 'yourpassword';
