I have a problem with email in laravel. That's my mail.php file:

<?php

return array(

	/*

	| Mail Driver
	|--------------------------------------------------------------------------
	|
	| Laravel supports both SMTP and PHP's "mail" function as drivers for the

	| Supported: "smtp", "mail", "sendmail"
	|
	*/

	'driver' => 'smtp',

	/*
	|--------------------------------------------------------------------------
	| SMTP Host Address
	|--------------------------------------------------------------------------
	|
	| Here you may provide the host address of the SMTP server used by your
	| applications. A default option is provided that is compatible with
	| the Mailgun mail service which will provide reliable deliveries.
	|
	*/

	'host' => 'smtp.gmail.com',

	/*
	|--------------------------------------------------------------------------
	| SMTP Host Port
	|--------------------------------------------------------------------------
	|
	| This is the SMTP port used by your application to delivery e-mails to
	| users of your application. Like the host we have set this value to
	| stay compatible with the Mailgun e-mail applications by default.
	|
	*/

	'port' => 465,

	/*
	|--------------------------------------------------------------------------
	| Global "From" Address
	|--------------------------------------------------------------------------
	|
	| You may wish for all e-mails sent by your application to be sent from
	| the same address. Here, you may specify a name and address that is
	| used globally for all e-mails that are sent by your application.
	|
	*/

	'from' => array('address' => 'my_email', 'name' => 'my_name'),

	/*
	|--------------------------------------------------------------------------
	| E-Mail Encryption Protocol
	|--------------------------------------------------------------------------
	|
	| Here you may specify the encryption protocol that should be used when
	| the application send e-mail messages. A sensible default using the

	*/

	'encryption' => 'ssl',

	*/

	'pretend' => false,

);

And when I want to send an email, laravel display me this error

Swift_TransportException

Connection could not be established with host smtp.gmail.com [Connection timed out #110]

And that't the code of this error:

     }
    $options = array();
    if (!empty($this->_params['sourceIp'])) {
    $options['socket']['bindto']=$this->_params['sourceIp'].':0';
    }
    $this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));
    if (false === $this->_stream) {
    throw new Swift_TransportException(
    'Connection could not be established with host ' . $this->_params['host'] .
    ' [' . $errstr . ' #' . $errno . ']'
