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?ing\s+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.
