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