Seconded; this is exactly what we've been finding. Invaluement is a great complement to Spamhaus for a fraction of the cost. I wouldn't put it as a front-line reject DNSBL, because some of the things that have been listed are not what I would class, for our customers, as spam - but those entries are distinctly greyhat at best in a lot of cases, and some IP range operators I've flagged as "list, delist, and whitelist_from_rcvd as needed" due to the mix of legitimate small senders and spammers. -kgd
