{

function index()
{

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

        $config = Array(

            'protocol' => 'smtp',
            'smtp_host' => 'ssl://smtp:gmail.com',
            'smtp_port' => '465',
            'smtp_user' => '[e-mail]',
            'smtp_pass' => 'facebook@123',
            'charset'   =>  'utf-8',
            'newline'=>"\r\n"
        );



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

        $this->email->set_newline("\r\n");

        $this->email->from('[e-mail]','Elsner');

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

        $this->email->subject('This is Test email');

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


        $this->email->send();








        if($this->email->send())
        {
            echo "email sent";


        }
        else
        {

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

Answer 1

Use smtp.gmail.com instead of smtp:gmail.com as hostname.

'smtp_host' => 'ssl://smtp.gmail.com'
