Bounced emails not being procecessed

Hi!
My bounced emails are not automatically being processed.
Is there there something wrong with my config settings?
They are being delivered to my listbounce email box that I specified, no problem.

I also have setup cron job successfully to send out 200 emails per hour, I don’t know if that has anything to do with things.

$message_envelope = ‘listbounces@xxxcom’;
$bounce_protocol = ‘pop’;
$bounce_mailbox_host = ‘xxx’;
$bounce_mailbox_user = ‘* removed ';
$bounce_mailbox_password = ’
removed *’;
$bounce_mailbox_port = “995/pop3/ssl/novalidate-cert”;

$bounce_mailbox_purge = 1;
$bounce_mailbox_purge_unprocessed = 1;
$bounce_unsubscribe_threshold = 2;

define(‘MANUALLY_PROCESS_BOUNCES’, 0);
define(‘BLACKLIST_EMAIL_ON_BOUNCE’, 1);

Any ideas? Thanks!
