What exactly is meant by "monitored". If passive probing is disabled (see below), a max(2) setting will unsubscribe an invalid address IF there is at least 2 list distributions within 20 days? In other words, given the below example, if the list only goes out once every 30 days, bad addresses will not be unsubscribed correct?

If after 20 days there are no more errors, they are removed from monitoring. If they error again within the 20 days, they will be removed and you will be notified. With Probe (5) 1/5 of the subscribers will be probed with each message sent. At this rate all users will have been probed after about 5-6 weeks. Depending on your needs, you can adjust all this accordingly.
