An organization that blocks 90% of spam with no false positives is incredibly useful.
Using a greylisting system is equally effective without the black list part.
Hi. I'm the guy who wrote the CEAS paper on greylisting.
Greylisting is useful, but anyone who thinks it's a substitute for DNSBLs has never run a large mail system.
We use the black lists for scoring spam messages, but we never outright block messages. I was not implying that blacklists are not useful at all. I just see things in shades of grey over black and white. Of the 17 domains we have with roughly 250 users it does well enough. Regards, Seth
