NAME

       Courier::Filter::Module::DNSBL - DNS black-list filter module for the Courier::Filter framework

SYNOPSIS

	   use Courier::Filter::Module::DNSBL;

	   my $module = Courier::Filter::Module::DNSBL->new(
	       zones	   => @dns_zones,

	       logger	   => $logger,
	       inverse	   => 0,
	       trusting    => 0,
	       testing	   => 0,
	       debugging   => 0
	   );

	   my $filter = Courier::Filter->new(
	       ...
	       modules	   => [ $module ],
	       ...
	   );

DESCRIPTION

       This class is a filter module class for use with Courier::Filter.  It matches a message if the sending machine's IP address (currently IPv4
       only) is listed by one of the configured DNS black-lists.

   Constructor
       The following constructor is provided:

       new(%options): returns Courier::Filter::Module::DNSBL
	   Creates a new DNSBL filter module.

	   %options is a list of key/value pairs representing any of the following options:

	   zones
	       Required.  A reference to an array containing the DNS zone names of the black-lists to be used.

	   All options of the Courier::Filter::Module constructor are also supported.  Please see "new()" in Courier::Filter::Module for their
	   descriptions.

   Instance methods
       See "Instance methods" in Courier::Filter::Module for a description of the provided instance methods.

NAME

       Courier::Filter::Module::Header - Message header filter module for the Courier::Filter framework

SYNOPSIS

	   use Courier::Filter::Module::Header;

	   my $module = Courier::Filter::Module::Header->new(
	       fields	   => \%patterns_by_field_name,
	       response    => $response_text,

	       logger	   => $logger,
	       inverse	   => 0,
	       trusting    => 0,
	       testing	   => 0,
	       debugging   => 0
	   );

	   my $filter = Courier::Filter->new(
	       ...
	       modules	   => [ $module ],
	       ...
	   );

DESCRIPTION

       This class is a filter module class for use with Courier::Filter.  It matches a message if one of the message's header fields matches the
       configured criteria.

   Constructor
       The following constructor is provided:

       new(%options): returns Courier::Filter::Module::Header
	   Creates a new Header filter module.

	   %options is a list of key/value pairs representing any of the following options:

	   fields
	       Required.  A reference to a hash containing the message header field names and patterns (as key/value pairs) that messages are to
	       be matched against.  Field names are matched case-insensitively.  Patterns may either be simple strings (for exact, case-sensitive
	       matches) or regular expression objects created by the "qr//" operator (for inexact, partial matches).

	       So for instance, to match any message from the "debian-devel" mailing list with the subject containing something about 'duelling
	       banjoes', you could set the "fields" option as follows:

		   fields      => {
		      'list-id'    => '<debian-devel.lists.debian.org>',
		       subject	   => qr/duell?ings+banjoe?s?/i
		   }

	   response
	       A string that is to be returned literally as the match result in case of a match.  Defaults to "Prohibited header value detected:
	       <field>: <value>".

	   All options of the Courier::Filter::Module constructor are also supported.  Please see "new()" in Courier::Filter::Module for their
	   descriptions.

   Instance methods
       See "Instance methods" in Courier::Filter::Module for a description of the provided instance methods.
