ISPConfig and VMail folders

Hi all..

I'm using roundcube with ISPConfig.

ISPConfig dont create a Sent, Draft, Junk (in /var/vmail/domain/user) and Trash folders when I create a new mail account.

How can I do to fix it?

I'm trying to input this code in /var/ww/ispconfig/mail/mail_user_edit.php

Code:

$Sent   = "/var/vmail/".$app->db->quote($_POST['email_domain'])."/".$this->dataRecord['email']."/.Sent";
$Drafts = "/var/vmail/".$app->db->quote($_POST['email_domain'])."/".$this->dataRecord['email']."/.Drafts";
$Junk   = "/var/vmail/".$app->db->quote($_POST['email_domain'])."/".$this->dataRecord['email']."/.Junk";
$Trash  = "/var/vmail/".$app->db->quote($_POST['email_domain'])."/".$this->dataRecord['email']."/.Trash";

mkdir($Sent, 0755);
mkdir($Drafts, 0755);
mkdir($Junk, 0755);
mkdir($Trash, 0755);

chmod($Sent, "vmail");
chmod($Drafts, "vmail");
chmod($Junk, "vmail");
chmod($Trash, "vmail");

But the webserver user cant create that..
