=head1 SYNOPSIS

See L.

=head1 DESCRIPTION

An object of class B represents a B
(C) record.

=head2 Constructors

The following constructors are provided:

=over

=item B: returns I

Creates a new Sender ID ("spf2.0") record object.

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

=over

=item B

=item B

=item B

See L.

=item B

I.  See L.  The B<'mfrom'> and B<'pra'> scopes
are supported.  There is no default.

sub new {
    my ($self, %options) = @_;
    $self = $self->SUPER::new(%options);

    if (not defined($self->{parse_text})) {
        # No parsing is intended, so scopes should have been specified:
        my $scopes = $self->{scopes} || [];
        @$scopes > 0
            or throw Mail::SPF::EInvalidScope('No scopes for spf2.0 record');
        foreach my $scope (@$scopes) {
            $scope =~ $self->valid_scope
                or throw Mail::SPF::EInvalidScope("Invalid scope '$scope' for spf2.0 record");
        }
    }

    return $self;
}

=item B: returns I;
throws I, I,
I

Creates a new Sender ID ("spf2.0") record object by parsing the string and
any options given.

=head2 Class methods

The following class methods are provided:

=over

=item B: returns I

Returns a regular expression that matches a version tag of B<'spf2.0/'> plus a
comma-separated list of any of the B<'mfrom'> and B<'pra'> scopes.  The
following are valid version tags:

    spf2.0/mfrom
    spf2.0/pra
    spf2.0/mfrom,pra
    spf2.0/pra,mfrom

=item B
