Hello, I am trying to send an email via my web application. It used to work but after the last upgrade of laravel something is breaking up. The message seems to arrive at Iron.io but it is never proccessed..

I have created a subscriber with the following command:

php artisan queue:subscribe u-support http://ptyxiakh.eu1.frbit.net/queue/demo

My routes file contains the following:

Route::post('communication',
array(
	'uses' => 'EmailController@store',
	'as' => 'contact.store'
))->before('csrf');

and

Route::post('queue/demo',function(){


	return Queue::marshal();
});

When I post the data from my form to communication the method store of the EmailController is triggered. Here is the import part and the constructor:

use Workflow\Services\Validation\EmailValidator;


class EmailController extends BaseController {


	protected $validator ;


	public function __construct(EmailValidator $validator){

		$this->validator = $validator;

	}

And bellow the store method:

public function store()
	{
	
	if(!$this->validator->validateForSending(Input::all())){

			return Redirect::route('contact.create')->withErrors($this->validator->errors());

	}
	

	Event::fire('mail.send',['data' => Input::all()]);



	return Redirect::route('contact.create')->with('flash_contact','Successfully sent mail');
	
	

	}

My queue configuration for the production environment contains the following:

'default' => 'iron',

and

'iron' => array(
			'driver'  => 'iron',
			'project' => 'my_project',
			'token'   => 'my_project_token',
			'queue'   => 'u-support',
		),

I have subscribed the event in app/start/global.php as following:

Event::subscribe('Workflow\Services\Handlers\EmailEventHandler');

My EmailEventHandler is the following:

<?php namespace Workflow\Services\Handlers;

use Workflow\Services\Mailers\UserMailer;
use Auth;
use User;
use Queue;

class EmailEventHandler{

protected $mail;

    function __construct(UserMailer $mail){

		/*We instantiate a UserMailer object to get 
		the proper functions to send an email
		*/

            $this->mail=$mail;

		

	}


public function onSend(array $data){

	/*User $user comes from the event firing in the controller
	*/

		 	Queue::push(function($job) use ($data){

		 		$this->mail->send($data);

		 		
		 	});
	 		
}

public function subscribe($events){

/*When the user.signup event is fired the method onSignup is 
running
*/

$events->listen('mail.send','Workflow\Services\Handlers\EmailEventHandler@onSend');

}

} 

My UserMailer which extends the Mailer class is the following:

<?php namespace Workflow\Services\Mailers;

use Auth;
use User;

class UserMailer extends Mailer{

	public function send(array $data){

		
		$view='emails.send';

	
		$dataToSend = ['name' => $data['name'],
						'email' => $data['email'],
						'subject' => $data['subject'],
						'comments' => $data['comments']


		];
		
	$this->receive($dataToSend['subject'],$view,$dataToSend);


	}

}

And finally my Mailer is the following:

<?php namespace Workflow\Services\Mailers;

use Mail;

abstract class Mailer{


public function receive($subject,$view,$data){


		Mail::send($view,$data,
			function($message) use($subject,$data) 
			{

				$message->to('giannhs905@gmail.com')->subject($subject);

			});
	
	}


}

Any idea why this breaks up??
