About FraudBL

FraudBL is an open source DNS Blacklist server, a part of the more common dnsbl.tornevall.org DNS Blacklist. FraudBL stands for Fraud Blacklist. This site itself is a landing page for Tornevall Networks blacklisting services and the real site, where most of our information resides can be reached via Tornevall Networks portal.

FraudBL is almost what tornevall.org is: While dnsbl.tornevall.org blocks regular spam, proxies and webabuse, FraudBL explicitly blocks servers known of sending spam based on phishing or anything else that would cause any economic loss for the receiver. Yes, spam usually do this too, but this service is explicitly for fraud. A futuristic plan is to involve e-commerce fraud, for which webstores is included to prevent fraudalent issues. However, as there’s a lot more legal things to take care of, that project is paused.

The purpose of FraudBL is about stopping fraudalent/phishinglike e-mail sent from different servers, that looks like they are sent from banks and others. FraudBL uses a separate spamresolver with the suffix bl.fraudbl.org. However, we are also using dnsbl.tornevall.org and hosts that is considered phishy/fraudalent are marked up with an extra TXT-entry.

To report fraudalent e-mail to us, send the mail content (important: with full header) to spam@fraudbl.org. To extract a message header, you may see a few examples at http://docs.tornevall.net/x/ZoBq (old link, probably dead due to confluence upgrades, we’ll be back with this) how to do this (covers gmail, outlook/hotmail/thunderbird/etc). The goal with this, is to block the server sources of the sent mail, not the sender itself, so it’s actually the “Receved”-headers we are looking for primarilly.

FraudBL is based in Sweden, but due to the need for higher capacity, secondary DNS is hosted via Linode.
