package Mail::SPF::Mod::Redirect;
=head1 NAME
Mail::SPF::Mod::Redirect - SPF record C<redirect> modifier class
=cut
use warnings;
use strict;
use Mail::SPF::Mod;
use base 'Mail::SPF::GlobalMod';
use constant TRUE => (0 == 0);
use constant FALSE => not TRUE;
use constant name => 'redirect';
use constant name_pattern => qr/${\name}/i;
use constant precedence => 0.8;
=head1 DESCRIPTION
An object of class B<Mail::SPF::Mod::Redirect> represents an SPF record
modifier of type C<redirect>.
=head2 Constructors
The following constructors are provided:
=over
=item B<new(%options)>: returns I<Mail::SPF::Mod::Redirect>
Creates a new SPF record C<redirect> modifier object.
%options is a list of key/value pairs representing any of the following
options:
=over
=item B<domain_spec>
See L<Mail::SPF::Mod/new>.
=back
=item B<new_from_string($text, %options)>: returns I<Mail::SPF::Mod::Redirect>;
throws I<Mail::SPF::ENothingToParse>, I<Mail::SPF::EInvalidMod>
Creates a new SPF record C<redirect> modifier object by parsing the string and
any options given.
=back
=head2 Class methods
The following class methods are provided:
=over
=item B<name>: returns I<string>
Returns B<'redirect'>.
=item B<name_pattern>: returns I<Regexp>
Returns a regular expression that matches a modifier name of B<'redirect'>.
=item B<precedence>: returns I<real>
Returns a precedence value of B<0.8>. See L<Mail::SPF::Mod/precedence>.
=back
=head2 Instance methods
The following instance methods are provided:
=over
=cut
sub parse_params {
my ($self) = @_;
$self->parse_domain_spec(TRUE);
return;
}
=item B<params>
See L<Mail::SPF::Mod/params>.
=cut
sub params {
my ($self) = @_;
return $self->{domain_spec};
}
=item B<domain_spec>: returns I<Mail::SPF::MacroString>
Returns the C<domain-spec> parameter of the modifier.
=cut
# Make read-only accessor:
__PACKAGE__->make_accessor('domain_spec', TRUE);
=item B<process($server, $request, $result)>: throws I<Mail::SPF::Result>
If no mechanism matched during the evaluation of the current SPF record,
performs a recursive SPF check using the given SPF server and request objects
and substituting the modifier's target domain name for the request's authority
domain. The result of the recursive SPF check is then thrown as the result of
the current record's evaluation. However, if the target domain has no
acceptable SPF record, a C<permerror> result is thrown. See RFC 4408, 6.1, for
details.
=cut
sub process {
my ($self, $server, $request, $result) = @_;
$server->count_dns_interactive_term($request);
# Only perform redirection if no mechanism matched (RFC 4408, 6.1/1):
$result->isa('Mail::SPF::Result::NeutralByDefault')
or return;
# Create sub-request with mutated authority domain:
my $authority_domain = $self->{domain_spec}->new(server => $server, request => $request);
my $sub_request = $request->new_sub_request(authority_domain => $authority_domain);
# Process sub-request:
$result = $server->process($sub_request);
# Translate result of sub-request (RFC 4408, 6.1/4):
$server->throw_result('permerror', $request,
"Redirect domain '$authority_domain' has no applicable sender policy")
if $result->isa('Mail::SPF::Result::None');
# Propagate any other results as-is:
$result->throw();
}
=back
