Postfilter README
Introduction
postfilter is an antispam filter for InterNetNews, a widely used NNTP server. Unlike cleanfeed - which checks remote articles, those messages sent through other sites - postfilter scans local posts and tries to reject spam and various abuses. Even if it"s designed for large sites, notably USENET servers, postfilter can be safety used also by small or private hosts that need a less strong protection against abuses.
Requirements
INN >= 2.4.0 compiled with perl support. It"s recommended to use INN >= 2.4.4. Everybody should note that postfilter is fully compatible with INN 2.5 even if some new feature of INN isn"t still used.
A relatively recent version of Perl, 5.6 is enough, 5.8 is much better for postfilter
The following perl modules:
Date::Parse
Net::DNS
