right. And if you don't tweak smtp_max_rcpts, those slow addresses 
force everyone delivered AFTER them to be held up. smpt_max-rcpts 
breaks teh delivery into many small batches, so any single slow 
address doesn't impact the entire delivery. If you don't change this 
value, every slow or down machine will kill your delivery. Until you 
do, nothing else you tweak will make much difference.
