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

DESCRIPTION
       An object of class Mail::SPF::Mech::PTR represents an SPF record mecha-
       nism 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 fol-
           lowing options:

           qualifier
           domain_spec
               See "new" in Mail::SPF::Mech.

       new_from_string($text): returns Mail::SPF::Mech::PTR; throws
       Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMech
           Creates a new SPF record "ptr" mechanism object by parsing the
           given string.

       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.
