How do messages to 2.8 million recipients > generate 14.8 million bounces? Two possibilities: 1) It's possible you have a recipient on a brain-dead system that generates multiple bounce replies - I've seen systems that will send back "unable to deliver, will retry" once an hour 168 times. ;) Of course, that shouldn't explain all the bounces you're seeing. 2) Don't forget bounces generated by stuff that doesn't generate any recipients, such as a bounced "Your message has been sent to the list owner" for a spam posting. Note that in *this* category, it's quite possible that you get back several bounces for the notice...
