Incentive to whom? The client? Of course there is. Beyond their normal problems encountered due to such a listing, they can be suspended from the whitelist until the blacklisting is addressed. Which means they are paying us for a service they aren't able to avail themselves of. They thus have plenty of incentive to work out the issues and get things fixed. Check the PDF table I sent earlier. You will see very few dnsbl hits for IPs on, and even off our lists. Do your own check. Query our lists and x-reference them to DNSBLs. Depending upon the dnsbl, we may warn, or suspend, for a single IP hit. (we prioritized our DNSBL use plan by weight, with the input of some senders, the MAAWG technical advisory board, some receivers (large ISPs)). The approach is published at support.senderscorecertified.com (this site might be down at the moment). Chronic DNSBL listings, or those affecting large proportions of a client IP space, or repeated offenses earns a client a trip to the woodshed, and if that doesn't get them to correct their errant ways, we invite them to no longer darken our door. It isn't worth it to them, nor to us. -- Neil Schwartzman Director, Accreditation Security & Standards Certified | Safelist Return Path Inc. 0142002038
