NAME

Mailfetch::Rule::DNSBL - check if IP is on a DNS blacklist

SYNOPSIS

  perl -MMailfetch::Rule::DNSBL=test,mailfile -e1

HOW IT WORKS

This rule uses Net::DNSBLLookup to determine the hosts through which the mail passed, according to the Received: headers, and checks them against blacklist entries.

Currently, no caching is performed.
