Interesting. I just added greylisting and my stats with MS reversed. I
run MailWatch and when I would log in the morning I would have only
12-15% of email id as clean. Now it is regularly 75-80% clean. And so
far it has only been one user that wanted their email now that had two
emails delayed. Luckily they complain so much nobody cared :)
Actually I had the most trouble with foward and reverse DNS. I turned
that off because my whitelist had grown to over a couple hundred
entries. With greylisting I've only had to add 5 or 6 domains.
