This was offered to someone that wanted no maintenance and posted 3 times a 
month.  With those posting habits, it would take 2 months for all subscribers 
to be probed. So I don't think that's very aggressive at all. Probe(30) would 
take 10 months. Actually, I would be more inclined to use Probe(1) on the first 
mailing, then back off to Probe(3) or (6).  

Sure, if YOUR list posted every day, the default would be fine. As it's been 
discussed here before, Auto-Delete= can either be useless or devastating to 
your list, unless it is set for it's individual posting habits. In other words, 
there is no one setting good for all lists.
