depends on how you have your SA setup, mines a  'no mercy' approach
his and yours clearly cant be.

Like I said try running greylisting on a network that does several 
million emails per day with several MX's, you might say ok retry in 1 
minute, but most daemons wait 10, so by the time one of our guys gets his 
email its 40-50 minutes later, i would want to hope they werent in a 
critical ebay auction.
