NAME
Mail::SPF::Record - Abstract base class for SPF records
SYNOPSIS
Creating a record from a string
use Mail::SPF::v1::Record;
my $record = Mail::SPF::v1::Record->new_from_string("v=spf1 a mx -all");
Creating a record synthetically
use Mail::SPF::v2::Record;
my $record = Mail::SPF::v2::Record->new(
scopes => ['mfrom', 'pra'],
terms => [
Mail::SPF::Mech::A->new(),
Mail::SPF::Mech::MX->new(),
Mail::SPF::Mech::All->new(qualifier => '-')
],
global_mods => [
Mail::SPF::Mod::Exp->new(domain_spec => 'spf-exp.example.com')
]
);
DESCRIPTION
Mail::SPF::Record is an abstract base class for SPF records. It cannot
be instantiated directly. Create an instance of a concrete sub-class
instead.
Constructor
The following constructors are provided:
new(%options): returns Mail::SPF::Record
Creates a new SPF record object.
%options is a list of key/value pairs representing any of the
following options:
text
A string denoting the unparsed text of the record.
scopes
A reference to an array of strings denoting the scopes that are
covered by the record (see the description of the "scope"
option of Mail::SPF::Request's "new" constructor).
terms
A reference to an array of Mail::SPF::Term (i.e.
Mail::SPF::Mech or Mail::SPF::Mod) objects that make up the
record. Mail::SPF::GlobalMod objects must not be included
here, but should be specified using the "global_mods" option
instead.
global_mods
A reference to an array of Mail::SPF::GlobalMod objects that
are global modifiers of the record.
new_from_string($text, %options): returns Mail::SPF::Record; throws
Mail::SPF::ENothingToParse, Mail::SPF::EInvalidRecordVersion,
Mail::SPF::ESyntaxError
Creates a new SPF record object by parsing the string and any
options given.
Class methods
The following class methods are provided:
version_tag_pattern: returns Regexp
Abstract. Returns a regular expression that matches a legal
version tag.
This method is abstract and must be implemented by sub-classes of
Mail::SPF::Record.
default_qualifier: returns string
Returns the default qualifier, i.e. '+'.
results_by_qualifier: returns hash of string
Returns a reference to a hash that maps qualifiers to result codes
as follows:
Qualifier | Result code
-----------+-------------
+ | pass
- | fail
~ | softfail
? | neutral
Instance methods
The following instance methods are provided:
text: returns string; throws Mail::SPF::ENoUnparsedText
Returns the unparsed text of the record. Throws a
Mail::SPF::ENoUnparsedText exception if the record was created
synthetically instead of being parsed, and no text was provided.
version_tag: returns string
Abstract. Returns the version tag of the record.
This method is abstract and must be implemented by sub-classes of
Mail::SPF::Record.
scopes: returns list of string
Returns a list of the scopes that are covered by the record. See
the description of the "new" constructor's "scopes" option.
terms: returns list of Mail::SPF::Term
Returns a list of the terms that make up the record, excluding any
global modifiers, which are returned by the "global_mods" method.
See the description of the "new" constructor's "terms" option.
global_mods: returns list of Mail::SPF::GlobalMod
Returns a list of the global modifiers of the record, ordered
ascending by modifier precedence. See the description of the "new"
constructor's "global_mods" option.
global_mod($mod_name): returns Mail::SPF::GlobalMod
Returns the global modifier of the given name if it is present in
the record. Returns undef otherwise. Use this method if you wish
to retrieve a specific global modifier as opposed to getting all of
them.
stringify: returns string
Returns the record's version tag and terms (including the global
modifiers) formatted as a string. You can simply use a
Mail::SPF::Record object as a string for the same effect, see
"OVERLOADING".
eval($server, $request): throws Mail::SPF::Result
Evaluates the SPF record in the context of the request parameters
represented by the given Mail::SPF::Request object. The given
Mail::SPF::Server object is used for performing DNS look-ups.
Throws a Mail::SPF::Result object matching the outcome of the
evaluation; see Mail::SPF::Result. See RFC 4408, 4.6 and 4.7, for
the exact algorithm used.
OVERLOADING
If a Mail::SPF::Record object is used as a string, the "stringify"
method is used to convert the object into a string.
