Unfortunately, many sending clients (newsletters, announcements, etc.) do not retry if the initial delivery fails.
That's impressively broken. Do you have specific examples?
Back when I was tuning my greylister I found some rather strange retries, but I don't recall many senders that didn't retry and didn't look like spambots.
