'Your server might not be configured to send mail using this method

I want to verify email when users register. I am using codeigniter3.

When I run on the localhost I do not receive any mail. I get this message " Unable to send email using PHP mail(). Your server might not be configured to send mail using this method. "

Here is my code : controllers/User.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
 
class User extends CI_Controller {
 
    function __construct(){
        parent::__construct();

        $this->load->library('form_validation');
        $this->load->library('session');
 
        //get all users
        $this->data['users'] = $this->users_model->getAllUsers();
    }
 
    public function index(){
        $this->load->view('register', $this->data);
    }
 
    public function register(){
        $this->form_validation->set_rules('email', 'Email', 'valid_email|required');

        if ($this->form_validation->run() == FALSE) { 
            $this->load->view('register', $this->data);
        }
        else{
            //get user inputs
            $email = $this->input->post('email');

In your configuration change protocol to "smtp"

$config = array(
    'smtp_host'=> "smtp.gmail.com",
    "smtp_user"=> 'Username', // YOUR Username
    "smtp_pass" => 'Password', // YOUR Password
    'protocol' => 'smtp',
    'smtp_crypto' => 'ssl',
    "smtp_port" => 465,
    'charset' => 'iso-8859-1',
    'wordwrap' => TRUE,
    'mailtype' => 'html',
    'newline'   => "\r\n"
);

If you are using gmail account, Make sure you have turn on "Less secure app" here
