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.
