-# Sample Perl filtering file for the innd hooks.
-#
-
-# This file gets loaded at innd process startup, and everytime a
-# "ctlinnd reload filter.perl 'reason'" or a
-# "ctlinnd reload all 'reason'" is done.
-#
-# Before this file is loaded, the perl routine `filter_before_reload' is
-# called, and after it's finished loading, the perl routine
-# `filter_after_reload' is called. See startup_innd.pl for more details.
-#
-# The following routines can be defined here for use by innd:
-#
-# sub filter_art { ... }
-#
-# This routine is called before every article is accepted for
-# posting. Is is called with no arguments, but has access to
-# all the non-empty standard headers of the article via the
-# global associative array `%hdr.' If it returns the empty
-# string ("") then the article is accepted. If it returns any
-# non-null string value, then the article is rejected and the
-# returned string value is logged as the reason why.
-#
-# The standard headers are:
-#
-# Approved, Control, Date, Distribution, Expires,
-# From, Lines, Message-ID, Newsgroups, Path,
-# Reply-To, Sender, Subject, Supersedes, Bytes,
-# Also-Control, References
-#
-# sub filter_mode { ... }
-#
-# This routine is called every time `go', `pause', or
-# `throttle' is called. It is called with no arguments and
-# returns no value. The global associative array `%mode' has
-# three keyed values stored in it:
-#
-# 'Mode' The current mode
-# ("running", "paused", "throttled")
-# 'NewMode" The new mode
-# 'reason' The reason given.
-#
-# For example: %mode = ('Mode', 'running',
-# 'NewMode', 'throttled',
-# 'reason', 'doing nightly backups')
-#
-# If filter_art is not defined when this file is done loading, then
-# filtering is disabled. If any syntax error occurs when loading the file,
-# then filtering is disabled.
-#
-# sub filter_messageid { ... }
-#
-# This routine is called when each article (in streaming
-# mode only) is checked to see if INN wants to accept the
-# article. If it returns the empty string, the article
-# is accepted. If it returns a non-empty value, the
-# article is refused. It is called with one argument,
-# the message-id to check.
-
-
-
-#
-# Called on each article innd receives from a peer. Return "" to accept,
-# and any other non-null string to reject. If rejecting the string returned
-# will be part of the logged reason.
-#
-
-sub filter_art {
- my $rval = "" ; # Assume we'll accept. Cannot be `0'
-
-### Remove two leading '##' from the following section (and then
-### "ctlinnd reload filter.perl 'reason'" and the filter will reject articles that
-### have "make money" in the subject, or are posted to more than 10
-### newsgroups.
-
-## my ($maxgroups) = 10 ;
-##
-### Normally this output would be lost, but if you run innd with '-d -f' you
-### can see what's going on.

-## $rval = "no money requests here"
-## } elsif ( ( @_ = split(",",$hdr{'Newsgroups'}) ) > $maxgroups ) {
-## $rval = "too many groups" ;
-### Kill article with "Re: " but no References:

-## $rval = "Followup without References:";

-## From Chrisophe Wolfhugel again (wolf@pasteur.fr). This is not
-## standalone code.
-##
-
-##Just for the fun, I've added following code to filter_innd.pl :
-##
-## ## Keep track of the From and subject.
-## $i = "$hdr{'From'} $hdr{'Subject'}";
-## push(@history, $i);
-## $history{$i}++;
-##
-## ## Reject the EMP.
-## if ($history{$i} > 10) {
-## $rval = "EMP rejected (appeared $history{$i} times): $i";
-## }
-##
-## ## Remove too old things.
-## while ($#history > 1000) {
-## delete($history{shift(@history)});
-## }
-##
-##It is pretty successfull in detecting and refusing excessive multi-posting.
-##Same sender, same subject, appearing more than 10 times without the last
-##1000 articles gets junked.
-##
-##Already catched a few hundreds :
-##
-##Nov 20 08:27:23.175 - vishnu.jussieu.fr <3292ac9a.4064710@nntp.cts.com> 437 EMP rejected (btr@trenet.com Be a Beta Tester!)
-##
-##That was just for the pleasure. It is still sucking a non significant CPU
-##time on my slow Alpha.
