Queue an Load Management Settings

Hi, while PL is running great an my customers shared hosting, I have trouble–or propbably it’s simple misunderstanding of the Queue and Load Management Settings. First I set an hourly amount of 1000 mails for our ~ 9000 adresses. With the shared hosting this was not a problem. Anyway I thought to reduce my spreading to 120 Mails every 10 Minutes. Since we get more unsubscription probably less of our mails got stuck in spam filters. But after two or three periods the queue keeps waiting and waiting and waiting. So I need to start over again and again. Here’s my settings:

Queue and Load management

define(‘MANUALLY_PROCESS_QUEUE’, 1);
// define(‘SHOW_PQCHOICE’,false);
define(‘MAX_PROCESS_MESSAGE’, 5);
define(‘PROCESSCAMPAIGNS_PARALLEL’,false);
define(‘MAILQUEUE_BATCH_SIZE’, 120);
define(‘MAILQUEUE_BATCH_PERIOD’, 600);
// define(‘MAILQUEUE_THROTTLE’, 1);
// define(‘USE_DOMAIN_THROTTLE’,0);
// define(‘DOMAIN_BATCH_SIZE’,5);
// define(‘DOMAIN_BATCH_PERIOD’,120);
// define(‘VERBOSE’, 1);
define(‘SEND_QUEUE_PROCESSING_REPORT’, false);

Can someone see an obvious misconfiguration?

Thanks in advance
Michael
