Introduction 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. If you have a support issue, please use our Get Support form. New manager tools are in development for our registered users to help manage their IP netblocks. The tools are currently in early access. If you are interested in these tools, please click here: Net Manager . If anyone would like to contribute to SORBS or has any suggestions for new detection routines, and/or hosts to be listed, the SORBS team would love to hear from you.
