Blacklist in detail:

This blacklist is marked as inactive and is not being checked at the moment. We will be tracking it to see if it goes to normal again. IPBL IPv4

This list is maintained by Thoroquel Systems LLC from Columbus, Ohio. The list has been initially created for their personal use but now is in public beta. They do not recommend using it directly to block connections.

IP's are added to the list if they send out bulk mail, do not honor unsubscribes and send to SPAM traps. If neceesary the list will contain a CIDR if the SPAM is being sent out from a large number of IPs.

Delisting is possible if you meet their critaria. The list of things to be carefull during requests is listed on their website.

We keep some statistics on blacklists. Below is the graph for We test blacklists by asking them to respond to known IP's that are blacklisted and known IP's that can't be blacklisted. Not every blacklist has such IP's, we test them with what is possible. We keep if we get any response or error messages and the response duration. Lower response times are better. These statistics may be useful for email server administrators to pick which blacklist to use.
