Sending Email with Cakephp 3 - email

Question

I've been using this library for sending mail
https://github.com/PHPMailer/PHPMailer
But I'm not getting the Email Send
Invalid address: (From): XXX
Array ( [error] => 1 [message] => Mailer Error: Invalid address: (From): XXX )
What I did : Disable 2 Step verification into Gmail
And Enabled Allow Less Secure Apps On
PagesController.php
<?php
namespace App\Controller;
class PagesController extends AppController
{
public $components = array("Email");
public function index()
{
$to = 'myemail#gmail.com';
$subject = 'Hi buddy, i got a message for you.';
$message = 'Nothing much. Just test out my Email Component using PHPMailer.';
try {
$mail = $this->Email->send_mail($to, $subject, $message);
print_r($mail);
} catch (Exception $e) {
echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
exit;
}
}
EmailComponent.php
<?php
namespace App\Controller\Component;
use Cake\Controller\Component;
use Cake\Core\App;
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require ROOT. '/vendor/phpmailer/phpmailer/src/Exception.php';
require ROOT. '/vendor/phpmailer/phpmailer/src/PHPMailer.php';
require ROOT. '/vendor/phpmailer/phpmailer/src/SMTP.php';
class EmailComponent extends Component {
public function send_mail($to, $subject, $message)
{
// date_default_timezone_set('Asia/Calcutta');
$sender = "XXX"; // this will be overwritten by GMail
$header = "X-Mailer: PHP/".phpversion() . "Return-Path: $sender";
$mail = new PHPMailer();
$mail->SMTPDebug = 2; // turn it off in production
$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->Username = "XXX";
$mail->Password = "XXX";
$mail->SMTPSecure = "tls"; // ssl and tls
$mail->Port = 587; // 465 and 587
$mail->SMTPOptions = array (
'tls' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
),
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
$mail->From = $sender;
$mail->FromName = "From Me";
$mail->AddAddress($to);
$mail->IsHTML(true);
$mail->CreateHeader($header);
$mail->Subject = $subject;
$mail->Body = nl2br($message);
$mail->AltBody = nl2br($message);
// return an array with two keys: error & message
if(!$mail->Send()) {
return array('error' => true, 'message' => 'Mailer Error: ' . $mail->ErrorInfo);
} else {
return array('error' => false, 'message' => "Message sent!");
}
}
}

Fixed I had to replace
thoses three lines in EmailComponent
$sender = "xxx#gmail.com";
$mail->Username = "xxx#gmail.com";
$mail->Password = "GMAIL_PASSWORD";
