Postfilter 0.7.3 (Default branch)
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.License: BSD License (original)Changes:
This release uses 'delete $hdr{'Header'};' instead of '$hdr{'Header'} = undef;'. The behavior of postfilter when an error is found inside banlist.conf is configurable. The maximum difference between the number of groups in Followup-To and in Newsgroups can be set. Articles that include the same groups inside Newsgroups: and Followup-To: can be rejected. Articles that come from TOR exit nodes can be filtered. A new tool, postfilter-legal.pl, can query and expire legal.log.Image

net::sip::receivechain

Net::SIP::ReceiveChain(3pm)				User Contributed Perl Documentation			       Net::SIP::ReceiveChain(3pm)

NAME

       Net::SIP::ReceiveChain - handle incoming packet by multiple receivers

SYNOPSIS

	 # create proxy which works as a registrar too, but
	 # all register requests should be authorized

	 my $registrar = Net::SIP::Registrar->new...
	 my $auth = Net::SIP::Authorize->new ....
	 my $reg_chain = Net::SIP::ReceiveChain->new(
	       [ $auth,$registrar ],
	       methods => [ 'REGISTER' ],
	 );

	 my $proxy = Net::SIP::StatelessProxy->new...
	 my $chain = Net::SIP::ReceiveChain->new(
	       [ $registrar,$proxy ]
	 );

DESCRIPTION

       This package is used to handle incoming packets by multiple receivers, e.g. make sure that requests for Net::SIP::Registrar will be
       authorized by Net::SIP::Authorize.

       Objects in the chain might be Net::SIP::Registrar, Net::SIP::StatelessProxy, Net::SIP::Authorize, Net::SIP::ReceiveChain itself and every
       other object which handles "receive" like described below.

CONSTRUCTOR

       new ( OBJECTS, %ARGS )
	   This creates a new registar object, OBJECTS is a reference to an array of objects implementing the "receive" method.

	   %ARGS can have the following keys:

	   filter  A callback which gets called during "receive" with all arguments of the method. If it returns TRUE the packet will be handled
		   by the chain, otherwise not.

	   methods If filter is not given but methods is it will set filter to a callback which accepts only the methods specified in the array
		   reference given to methods.

METHODS

       receive ( PACKET,LEG,FROM )
	   PACKET is the incoming packet, LEG is the Net::SIP::Leg where the packet arrived and FROM is the "ip:port" of the sender. Responses
	   will be send back to the sender through the same leg.

	   Called from the managing Net::SIP::Dispatcher object if a new packet arrives.

	   Returns TRUE if the packet was fully handled by one of the objects in the chain, else FALSE:

	   o	   If a filter was given checks the packet against the filter and returns FALSE if the filter does return FALSE.

	   o	   Otherwise it will call "receive" on all objects in the chain until one of these returns TRUE. In this case it will return TRUE.

	   o	   If no object in the chain handled the packet it will return FALSE.
