[imp] Folder problem, not shoing on sidebar or Folders tree

[Nicholas Stone]

Here is my problem.  I cannot get the folders to show up in the left 
hand side bar nor the folders tree view (folders.php).  Now in the open 
folder in the top right I can open the folders that are created and in 
the inbox in the send to folder dropdown they are listed.  Im not sure 
whats going on but here is my servers.php file for the IMAP server

$servers['imap'] = array(
    'name' => 'Linux Server',
    'server' => 'localhost',
    'hordeauth' => false,
    'protocol' => 'imap/ssl/novalidate-cert',
    'port' => 993,
    'maildomain' => 'stonehome.dyndns.org',
    'smtphost' => 'localhost',
    'smtpport' => 25,
    'realm' => '',
    'preferred' => '',
    'dotfiles' => true,
    'folders' => 'INBOX.',
    'namespace' => ''
);

Thx for any help
