Content Snippets from surbl.org

"We specialize in the SURBL® reputation data provided in near real-time feeds. This data can be used to secure mail flow, mobile communications (SMS), web access (safe browsing, DNS Firewalls) and many other activities. Our most well-known data set is the publicly provided Multi, but besides that we also offer privately available datasets (see below). They are not limited to mail operations. Currently we are providing Crypto address, Phone number, an E-Mail source list and newly activated domain feeds (Fresh)."

"Many of the feeds are available as RPZ (Response Policy Zone). RPZ datasets can be used to trigger actions in DNS firewalls, e.g. to block access to dangerous sites. We were involved in creating the first RPZ dataset."

"This data set lists domains of malicious or abused web sites. It can be used to filter or tag unsolicited messages based on links in the message body, regardless of sender IP addresses. It ideally complements filtering based on known bad sender IPs. Used together with sender lists, our intelligence datasets have proven to be a highly-effective way to detect 95% of unsolicited messages. An RPZ version of Multi is available privately."

"Fresh is a list of domains that have been recently added to TLD zone file delegations. It includes a UNIX Epoch timestamp of when we most recently detected the changes, and therefore gives an indication of recently delegated domains. Since younger domains are more likely to be abusive, this can be used as one of multiple factors to help indicate domain reputation. Naturally, not all new domains are bad, but many bad domains are young. Selected subsets are available for RPZ."
