XBL holds the CBL data.

Exploits Block List
The Spamhaus Exploits Block List (XBL) is a realtime database of IP 
addresses of hijacked PCs infected by illegal 3rd party exploits, 
including open proxies (HTTP, socks, AnalogX, wingate, etc), worms/viruses 
with built-in spam engines, and other types of trojan-horse exploits.

If your IP address is listed by the XBL, see the XBL FAQs for solutions

Incorporates CBL data and NJABL proxy data

The XBL wholly incorporates data from two highly-trusted DNSBL sources, 
with tweaks by Spamhaus to maximise the data efficiency and lower False 
Positives. The main components are:
- the CBL (Composite Block List) from
- the NJABL Open Proxy IPs list from

XBL Usage

The Exploits Block List can be used by all modern mail servers, by setting 
your mail server's anti-spam DNSBL feature (sometimes called "Blacklist 
DNS Servers" or "RBL servers") to query XBL is also part 
of a combined DNSBL comprising SBL, XBL and PBL, see: ZEN
