[imp] runaway process

[Ben Sodenkamp]

Hello imp experts,

  I have imp 4.0.4 running on horde 3.0.5.  I am authenticating with a
Courier Imap server.  I have never had a working configuration, but I am
trying to adopt imp.

  Whenever I click on mail, The webserver makes a runaway process that
that rises to 90ish % utilization of the cpu within about 30 seconds.  I
have checked my server.php.  My server entry:

$servers['rcc'] = array(
    'name' => 'RCC IMAP Server',
    'server' => 'x.x.x.x',
    'hordeauth' => false,
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => 'INBOX.',
    'namespace' => 'INBOX.',
    'maildomain' => 'roboticat.com',
    'smtphost' => 'x.x.x.x',
    'smtpport' => xx,
    'dotfiles' => false,
    'hierarchies' => array());


I don't know where to begin to troubleshoot this problem, but I would
really like to use imp.  Any help appreciated.

Thanks,

Ben
