Report an IP address as a spam source

Please help us to improve our accuracy. We need your support to list as many spammers as possible in the inps.de-DNSBL to allow our customers a better spam protection. Here can you report us a suspicious IP address.

This IP address was found in DNS whitelist. A manual listing in our blacklist by users is not available for such IP addresses to ensure the accuracy of the inps.de-DNSBL. Maybe, it belongs to a freemail provider. In such cases, take a look to the source code of the spam e-mail, follow the "Received:" headers and search for the IP, where the e-mail originally was sent from.
