NAME
       Mail::SPF::Mech::PTR - SPF record "ptr" mechanism class
DESCRIPTION
       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.
