[imp] courier/imp: problem using shared folders containing subfolders

[Tobias Eigen]

Hi all, 

I am running I would be grateful for advice with the following shared folders 
issue on a system with the following: 

MTA: Courier
Horde: 2.1 
IMP: 3.1 (run IMP tests) 
Turba: 1.1 
PHP Version: 4.3.2 
PHP Major Version: 4.3 
PHP Minor Version: 2 

The problem is this: My shared folders are working great, except when there is 
a subfolder inside a shared folder, ie:

04-Marketing
04-Marketing.Events
04-Marketing.Materials
04-Marketing.Press

In the case above, I am unable to save a copy of a message in 04-Marketing or  
browse to it. If I unsubscribe to Events, Materials and Press, it will work 
normally. There is a period after the name in the folders pulldown list. 

Any ideas? I think my servers.php is set up right: 

$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'localhost',
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => '',
    'maildomain' => $DomainName,
    'smtphost' => 'localhost',
    'realm' => $DomainName,
    'preferred' => ''
);

Again, any help would be much appreciated. I've spent alot of time searching 
and have had no luck! 

Best wishes, 

Tobias
