4 multi_dnsbl is a DNS emulator daemon that increases the efficacy of DNSBL
5 look-ups in a mail system. multi_dnsbl may be used as a stand-alone DNSBL or as
6 a plug-in for a standard BIND 9 installation. multi_dnsbl shares a common
7 configuration file format with the Mail::SpamCannibal sc_BLcheck.pl script so
8 that DNSBL's can be maintained in a common configuration file for an entire
11 Because DNSBL usefulness is dependent on the nature and source of spam sent to
12 a specific site and because sometimes DNSBL's may provide intermittant service,
13 multi_dnsbl interrogates them sorted in the order of greatest successful hits.
14 DNSBL's that do not respond within the configured timeout period are not
15 interrogated at all after 6 consecutive failures, and thereafter will be
16 retried not more often than once every hour until they come back online. This
17 eliminates the need to place DNSBL's in a particular order in your MTA's config
18 file or periodically monitor the DNSBL statistics and/or update the MTA config
