[horde] Delayed Login - IMP - Going through all Mailfolders

[Stefanie Clormann]

Dear List,

we do have the following problem:

When logging in, users with big mailboxes and messages sizes
experience some very long login times.
This is causes by the IMP-module which scans the complete
IMAP folder hierarchy for unread messages.
Is there a way to speed this procedure up?

We do have the following setup in servers.php:

|'imap_config' => array(
    'children' => false,
    'namespace' => array(
        'INBOX/' => array(
            'name' => 'INBOX/',
            'delimiter' => '/',
            'type' => 'personal',
            'hidden' => false,
        ),
    ),
    'search_charset' => array(
        'UTF-8' => true
    )
)|


Thanks for any help.
Stefanie
