The SORBS (Spam and Open Relay Blocking System) provides free access to its DNS-based Block List (DNSBL) to effectively block email from more than 12 million host servers known to disseminate spam, phishing attacks and other forms of malicious email. The list typically includes email servers suspected of sending or relaying spam, servers that have been hacked and hijacked, and those with Trojan infestations. In an attempt to provide preemptive protection, SORBS also lists servers with dynamically allocated IP addresses. SORBS maintains 17 distinct DNSBL zones.

Listing Policy

The IP that is not to be scanned, is placed into the block.dnsbl.sorbs.net blacklist. This list can then be used by others as a way of classifying hosts as not wanting to be scanned. Interpretation of what that means is up to the administrator that chooses to use the block.dnsbl.sorbs.net blacklist.
