What is Tornevall?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
dnsbl.tornevall.org checks IPs. Tornevall Networks runs it, and we class it as low-impact.
How to get off it
Enter the IP on the removal page and run the check. Delist appears if it is listed. To check a small range, open Advanced, which takes up to a block of 256 addresses. DNS can take a while to catch up, and many requests can add penalty time. Do not ask through comments.
The site's pages we read cover removal more than why an IP gets listed. Tell us the IP on the SOS Hotline and we will look with you.
What "low-impact" means on these pages: the big mailbox providers rarely use the list, so it rarely affects delivery at Gmail, Outlook or Yahoo. It can still point at something worth fixing.
Want a hand getting this delisted? Here is how to write to a list's operator, or ask a person on our free SOS Hotline. Tell us the list and the IP or domain, and we reply within 48 to 72 hours.
A separate job: cleaning your list does not remove a listing. If you also want to know who on your list is safe to send to, clean your first 1,000 free.
