Right now we have only found phplist which so far I cant get working at all. They say you can adjust the seconds between messages.

"The MAILQUEUE_THROTTLE setting inserts a pause (in seconds) between each message, i.e. it will space messages apart by a number of seconds."

Example:
# batch processing disabled:
define("MAILQUEUE_BATCH_SIZE",0);

# Batch_period is not effective when batch processing is disabled:
define("MAILQUEUE_BATCH_PERIOD",3600);

# Pause between messages (in seconds) to send no more than 360 messages per hour:
define('MAILQUEUE_THROTTLE',10);
