[Paul Kelly] Care to share percentages maybe? :)

 [Paul Kelly] Believe it or not, 10 domain names from the 43k or so hosted on our Qmail cluster get 94% of all e-mail. One of them is a medical research company. I suspect someone out there doesn't like them :-)

Top 10 domains received 20,000,000 (yes 20 million) + spam rejections in the last 10 days.

It's a wee bit crazy.
