[imp] IMP No quota extension

[Ralph Sikau]

Hi,

I get every minute the following error message in the log:
"WARN: HORDE [imp] [getQuotaRoot] The server does not support the QUOTA 
extension. [pid 9075 on line 730 of "/usr/share/horde/imp/lib/Imap.php"]
ERR: HORDE [imp] Speicherplatz-Kontingent konnte nicht gelesen werden 
[pid 9075 on line 48 of "/usr/share/horde/imp/lib/Quota/Imap.php"]
It's a dovecot imap server. My backends.local.php contains:
$servers['imap'] = array(
         'name' => 'IMAP Server',
         'hostspec'  => 'localhost',
         'hordeauth' => 'full',
         'protocol'  => 'imap',
         'preferred' => true,
         'port'      => 143,
         'secure'    => 'tls',
         'quota' => array('driver'=>'imap'),
         'acl' => false,
);
I do not need the quota support. How can I get rid of these error messages?

Regards,
Ralph
