'smtp_port' => 25,
'smtp_user' => 'noreply@holaa.in',
'smtp_pass' => 'XXXXXXXXX',
'mailtype' => 'html',
'charset' => 'iso-8859-1'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('noreply@holaa.in');
$this->email->to($receiver);
$this->email->subject($subject);
$this->email->message($message);
