Laravel 5(.2) - send mail to log file

I have problem with sending mails to log file. I checked similar topics here, but didnt find any solution.

When I fill up contact form and submit I get error

Swift_TransportException in AbstractSmtpTransport.php line 383: Expected response code 250 but got code "530", with message "530 5.7.1 Authentication required "

My form.blade.php

{!! Form::open(array('route' => 'contact_store', 'class' => 'form')) !!}
<div class="form-group">
{!! Form::label('Your Name') !!}
{!! Form::text('name', null, 
    array('required', 
          'class'=>'form-control', 
          'placeholder'=>'Your name')) !!}
</div>

<div class="form-group">
{!! Form::label('Your E-mail Address') !!}
{!! Form::text('email', null, 
    array('required', 
          'class'=>'form-control', 
          'placeholder'=>'Your e-mail address')) !!}
</div>

<div class="form-group">
{!! Form::label('Your Message') !!}
{!! Form::textarea('message', null, 
    array('required', 
          'class'=>'form-control', 
          'placeholder'=>'Your message')) !!}
</div>

<div class="form-group">
{!! Form::submit('Contact Us!', 
  array('class'=>'btn btn-primary')) !!}
</div>{!! Form::close() !!}

ContactController.php function

public function store(ContactFormRequest $request) {

    \Mail::raw ('test', function($message) {
            $message->from('test@test.pl');
            $message->to('test@test.com', 'Admin')->subject('TODOParrot Feedback');
            });
    return redirect('/contact')->with('message', 'Ok!');
}

mail.php setup

'driver' => env('MAIL_DRIVER', 'log'),

Did I missed some configuration? I have no idea.
