High traffic Usage

If you think your servers periodically go over 1,000 requests per second you can still use our service, but be aware our servers will ignore the requesting IP for a period each time requests exceed 1,000 per second and your servers will not be protected using the "Zero Spam Project" service during that time.

If you operate high traffic mail server(s) and consistently exceed 1,000 request per second limit or want access to our professional dnsbl services please contact us by selecting "Service Request" in the form to the right to request unrestricted access to our dnsbl servers for the best anti-spam results.

Premium access in access of greater than 1,000 query requests/second is available for for a monthly fee of $200 per 1,000/second.
