Default folders

[jager]

Hello.

I'm trying to add some default folders to my roundcube configuration.
In my inbox i have the sent/spam/trash folders

Inbox.trash
Inbox.sent

How can i make these default?
I already tryed this:

$rcmail_config['INBOX.Sent_mbox'] = 'Sent';

Inbox.sent

How can i make these default? I already tryed this:

$rcmail_config['INBOX.Sent_mbox'] = 'Sent';

$rcmail_config['sent_mbox'] = 'Inbox.sent';
$rcmail_config['trash_mbox'] = 'Inbox.trash';
