An object of class Mail::SPF::Mech::PTR represents an SPF record mechanism of type "ptr".Constructors
The following constructors are provided:- new(%options): returns Mail::SPF::Mech::PTR
-
Creates a new SPF record "ptr" mechanism object.
%options is a list of key/value pairs representing any of the following options:
-
- qualifier
- domain_spec
- See ``new'' in Mail::SPF::Mech.
-
- new_from_string($text, %options): returns Mail::SPF::Mech::PTR; throws Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMech
- Creates a new SPF record "ptr" mechanism object by parsing the string and any options given.
Class methods
The following class methods are provided:- default_qualifier
- qualifier_pattern
- See ``Class methods'' in Mail::SPF::Mech.
- name: returns string
- Returns 'ptr'.
- name_pattern: returns Regexp
- Returns a regular expression that matches a mechanism name of 'ptr'.
Instance methods
The following instance methods are provided:- text
- qualifier
- params
- stringify
- See ``Instance methods'' in Mail::SPF::Mech.
- domain_spec: returns Mail::SPF::MacroString
- Returns the "domain-spec" parameter of the mechanism.
- match($server, $request): returns boolean
- Checks whether the mechanism's target domain name, or a sub-domain thereof, is a ``valid'' domain name for the given request's IP address (see ``ip_address'' in Mail::SPF::Request), and returns true if it does, or false otherwise. See ``valid_domain_for_ip_address'' in Mail::SPF::Util for how domains are validated. See RFC 4408, 5.5, for the description of an equivalent algorithm.
