Sending Mail using CakePHP 3.0 - email

Question

I am developing a website with new version 3.0 of CakePHP Framework. I am working on localhost and would like to send an email after a user has filled a form. Below is the code in my controller to send the email.
public function index(){
if ($this->request->is('post'){
$email = new Email();
$email->from([$this->request->data["sender"] => "Sender"]
->to("myEmail#hotmail.com")
->subject($this->request->data["Subject"])
->send($this->request->data["message"]);
}
}
When this code is executed nothing happen, no error, no message in my mailbox. I have seen that it exist in cakephp3.0 a class called DebugTransport but I don't know how to use it in order to debug my code. Someone has already use it ?

Hi thanks everyone for your answer.
By using mailjet.com I was able to send e-mails in localhost. Below the different steps:
Step 1
Create an account on mailjet website
Step 2
In app.php add a new entry in the table EmailTransport. The different parameter host, port, username and password can be found on mailjet website.
'EmailTransport' => [
'default' => [
'className' => 'Mail',
// The following keys are used in SMTP transports
'host' => 'localhost',
'port' => 25,
'timeout' => 30,
'username' => 'user',
'password' => 'secret',
'client' => null,
'tls' => null,
],
'mailjet' => [
'host' => 'in-v3.mailjet.com',
'port' => 587,
'timeout' => 60,
'username' => 'xxxxx',
'password' => 'xxxxx',
'className' => 'Smtp'
]
],
Step 3
In your controller
<?php
namespace App\Controller;
use App\Controller\AppController;
use Cake\Network\Email\Email;
class ContactController extends AppController {
var $helpers = array('Html');
public function index(){
if($this->request->is('post')){
$userName = $this->request->data['firstname'] . " " . $this->request->data['lastname'];
$email = new Email();
$email->transport('mailjet');
try {
$res = $email->from([$this->request->data['email'] => $userName])
->to(['myEmail#hotmail.com' => 'My Website'])
->subject('Contact')
->send($this->request->data['message']);
} catch (Exception $e) {
echo 'Exception : ', $e->getMessage(), "\n";
}
}
}

You had to use a SMTP server for delivery your email from your localhost in your config email.
There are 2 ways to achieve this:
Use it from a real server with a mail configuration
Use SMTP server for your test on your localhost. there are a lot of SMTP server with let you use it.
