Short for Spam URI Real-time Block Lists,
it is used to detect spam
based on message body URIs (usually Web sites). SURBLs
are not used to block spam senders. Instead they allow you to block messages
that have spam hosts that are mentioned in message bodies.
In order to use SURBL you need software that can parse URIs in message bodies,
extract their hosts, and check those against a SURBL list.
SURBL - Spam URI Realtime Blocklists SURBLs differ from most other RBLs in that they're used to detect spam based on message body URIs (usually web sites). Unlike most other RBLs, SURBLs are not used to block spam senders. Instead they allow you to block messages that have spam hosts which are mentioned in message bodies.
Using Exim to do SURBL checks to fight spam This document describes using the SURBL (Spam URI Realtime Blocklists) in conjunction with the Exim MTA. This utilizes Exim's DATA ACL and Exim's embedded Perl engine.
