[imp] Problem with IMP and Courier (probably message count)

[FrédéricVeillepeau]

Hi everybody,

I have a problem with IMP when I view a message. The message count is false 
(indicates I read message 1 of 0), and I have the warning :

Notice: Undefined index: 2 in /xxx/horde/imp-3.1/message.php on line 219

The mail server I am connecting to is a Courier server, not under my control 
(Web Host).

I suspect Courier is loosing the count of message, giving a wrong index to IMP.

Here are some of my parameters :
PHP 4.3.0
Horde 2.1
IMP 3.1
Server configuration :
$servers['MyServer'] = array(
    'name' => 'MyServer',
    'server' => 'mail.myserver.com',
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => 'INBOX.',
   'maildomain' => 'myserver.com',
    'smtphost' => 'smtp.myserver.com',
    'realm' => 'myserver.com',
    'preferred' => ''
);

Thanks a lot
