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.
escalations.dnsbl.sorbs.net - This zone contains netblocks of spam supporting service providers, including those who provide websites, DNS or drop boxes for a spammer. Spam supporters are added on a 'third strike and you are out' basis, where the third spam will cause the supporter to be added to the list.
