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.

spam.dnsbl.sorbs.net is the final step in the spam blacklists and contains all data from old.dnsbl.sorbs.net, which in turn contains all the data in recent.dnsbl.sorbs.net and new.dnsbl.sorbs.net. spam.dnsbl.sorbs.net lists offenders that have no intention of stopping spam, and will continue to be a burden on the inboxes of email users the world over. These hosts have further not made any effort to ask for delisting of any kind from SORBS.
