SpamAssassin Rule: URIBL_OB_SURBL

Standard description: Contains an URL listed in the OB SURBL blocklist

The mail body contains a URI containing a domain that has matched an entry on the DNSBL Outblaze URI Blacklist (SURBL).

Outblaze describes the data as coming from spam trap message body analysis and from user reports via a "this is spam" button. SURBL applies additional policies to its version of the Outblaze URI data that are published as ob.surbl.org. The user reports are also used, but not directly.

The default scores for this rule can be found in the online list of tests.
