== SpamAssassin Rule: RCVD_IN_XBL ==

''Standard description:'' Received via a relay in Spamhaus XBL

=== Explanation ===

The mail was received from a server listed in the [[http://www.spamhaus.org/xbl/|Spamhaus Exploits Block List]] [[DnsBlocklists|DNSBL]], which lists hijacked PCs infected by illegal 3rd party exploits.

  ''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 [[http://cbl.abuseat.org|cbl.abuseat.org]]
    * the NJABL Open Proxy IPs list from [[http://www.njabl.org|www.njabl.org]].
  ''

=== Further Info ===

The default scores for this rule can be found [[http://spamassassin.apache.org/tests.html|in the online list of tests]].
