NAME

Mail::SPF::Result - SPF result class

SYNOPSIS

For the general usage of Mail::SPF::Result objects in code that calls Mail::SPF, see Mail::SPF. For the detailed interface of Mail::SPF::Result and its derivatives, see below.

Throwing results

package Mail::SPF::Foo;
use Error ':try';
use Mail::SPF::Result;

sub foo {
    if (...) {
        throw Mail::SPF::Result::Pass($request);
    }
    else {
        throw Mail::SPF;;Result::PermError($request, 'Invalid foo');
    }
}

Catching results

package Mail::SPF::Bar;
use Error ':try';
use Mail::SPF::Foo;

try {
    Mail::SPF::Foo->foo();
}
catch Mail::SPF::Result with {
    my ($result) = @_;
    my $code     = $result->code;
    my $request  = $result->request;
    my $text     = $result->text;
};

DESCRIPTION

An object of class Mail::SPF::Result represents the result of an SPF request.

There is usually no need to construct an SPF result object directly using the new constructor. Instead, use the throw class method to signal to the calling code that a definite SPF result has been determined. In other words, use Mail::SPF::Result and its derivatives just like exceptions. See Error or "eval" in perlfunc for how to handle exceptions in Perl.

Constructor

The following constructor is provided:

new($request): returns Mail::SPF::Result
new($request, $text): returns Mail::SPF::Result

Creates a new SPF result object and associates the given Mail::SPF::Request object with it. An optional result text may be specified.

Class methods

The following class methods are provided:

throw($request): throws Mail::SPF::Result
throw($request, $text): throws Mail::SPF::Result

Throws a new SPF result object, associating the given Mail::SPF::Request with it. An optional result text may be specified.

name: returns string

Returns the trailing part of the name of the Mail::SPF::Result::* class on which it is invoked. For example, returns NeutralByDefault if invoked on Mail::SPF::Result::NeutralByDefault. This method may also be used as an instance method.

code: returns string

Returns the result code ("pass", "fail", "softfail", "neutral", "none", "error", "permerror", "permerror") of the Mail::SPF::Result::* class on which it is invoked. This method may also be used as an instance method.

class_by_code($code): returns class

Maps the given result code to the corresponding Mail::SPF::Result::* class. If an unknown result code was specified, returns undef.

is_code($code): returns boolean

If the class (or object) on which this method is invoked represents the given result code (or a derivative code), returns true. Returns false otherwise. This method may also be used as an instance method.

For example, Mail::SPF::Result::Pass->is_code('pass') returns true.

Instance methods

The following instance methods are provided:

throw: throws Mail::SPF::Result
throw($request): throws Mail::SPF::Result
throw($request, $text): throws Mail::SPF::Result

Re-throws an existing SPF result object. If a Mail::SPF::Request object is specified, associates it with the result object, replacing the prior request object. If a result text is specified as well, overrides the prior result text.

code: returns string

Returns the result code of the result object.

request: returns Mail::SPF::Request

Returns the SPF request that led to the result at hand.

text: returns string

Returns the text message of the result object.

stringify: returns string

Returns the result's name and text message formatted as a string. You can simply use a Mail::SPF::Result object as a string for the same effect, see "OVERLOADING".

OVERLOADING

If a Mail::SPF::Result object is used as a string, the "stringify" method is used to convert the object into a string.

RESULT CLASSES

The following result classes are provided:

Mail::SPF::Result::Pass
Mail::SPF::Result::Fail

The following additional instance method is provided:

explanation: returns string

Returns the explanation string for the fail result. Be aware that the explanation is provided by a potentially malicious party and thus should not be trusted. See RFC 4408, 10.5, for a more detailed discussion of this issue.

Mail::SPF::Result::SoftFail
Mail::SPF::Result::Neutral
Mail::SPF::Result::NeutralByDefault

This is a special-case of the neutral result that is thrown as a default when "falling off" the end of the record during evaluation. See RFC 4408, 4.7.

Mail::SPF::Result::None
Mail::SPF::Result::Error

The following sub-classes of Mail::SPF::Result::Error are provided:

Mail::SPF::Result::PermError
Mail::SPF::Result::TempError
