Disabling mailinglist.

Hi!
I have question about disabling mailinglist for users. We are doing lists by hand.
Is it okay if i comment out in

Code:

/usr/local/ispconfig/interface/web/mail/lib/module.conf.php

that

PHP:

//**** Mailinglist menu
$items = array();

if($app->auth->get_client_limit($userid,'mailmailinglist') != 0)
{
        $items[] = array( 'title' <---->=> 'Mailing List',
                                        'target'     => 'content',
                                        'link'        => 'mail/mail_mailinglist_list.php',
                                        'html_id' => 'mail_mailinglist_list');
}

if(count($items))
{
        $module['nav'][] = array(<----->'title'>=> 'Mailing List',
                                                                'open' >=> 1,
                                                                'items'>=> $items);
}

 

Thank you, i knew it but i didn't thought that all.
