Postfilter is a Perl filter for Internet Net News (innd) that checks all messages sent by local users searching for spam and invalid content. Although it's designed for large sites that need a complex tool, it could also be used by local or private servers.

Changes:
The old single configuration file (postfilter.conf) was split into many smaller files. The logging subsystem is much better. The multipost can be allowed. Articles that come from TOR nodes can be rejected. There are many bugfixes.
