DESCRIPTION
       An object of class Mail::SPF::Request represents an SPF request.
   Constructors
       The following constructors are provided:
       new(%options): returns Mail::SPF::Request
           Creates a new SPF request object.  The request is considered the
           root-request for any subsequent sub-requests (see the
           "new_sub_request" constructor).
           %options is a list of key/value pairs representing any of the
           following options:
           versions
               A reference to an array of integers listing the versions of SPF
               records that may be used for the SPF check.  Only those record
               versions that cover the desired scope will actually be used.
               At least one applicable version must be specified.  For a
               single record version, a simple scalar may be specified instead
               of an array-ref.  Defaults to all versions that cover the
               desired scope (see below); defaults to [1, 2] for the default
               scope of 'mfrom'.
               The following versions are supported:
               1   Use "v=spf1" records.
               2   Use "spf2.0" records.
               Example:  A value of 1 (or [1]) means that only "v=spf1"
               records should be used for the SPF check.  If at the same time
               a scope of 'pra' is specified, a Mail::SPF::EInvalidScope
               exception will be thrown as "v=spf1" records do not cover the
               PRA scope.
           scope
               A string denoting the authorization scope of the identity that
               should be checked.  Defaults to 'mfrom'.  The following scope
               values are supported:
               'helo'
                   The given identity is the "HELO" parameter of an SMTP
                   transaction (RFC 2821) and should be checked against SPF
                   records that cover the "helo" scope ("v=spf1").  See the
                   SPFv1 specification (RFC 4408) for the formal definition of
                   the "HELO" scope.
               'mfrom'
                   The given identity is the "MAIL FROM" parameter of an SMTP
                   transaction (RFC 2821), and should be checked against SPF
                   records that cover the "mfrom" scope ("v=spf1" and
                   "spf2.0/mfrom").  See the SPFv1 specification (RFC 4408)
                   for the formal definition of the "MAIL FROM" scope.
                   Note:  In the case of an empty "MAIL FROM" SMTP transaction
                   parameter ("MAIL FROM:<>"), you should perform a check with
                   the "helo" scope instead.
               'pra'
                   The given identity is the "Purported Responsible Address"
                   of an internet message (RFC 2822) and should be checked
                   against SPF records that cover the "pra" scope
                   ("spf2.0/pra").  See the PRA specification (RFC 4407) for
                   the formal definition of the PRA scope.
           authority_domain
               A string denoting the domain name that should be queried for
               sender policy records.  Defaults to the domain of the
               "identity" option.  There is usually no need to specify the
               "authority_domain" option.
           identity
               Required.  A string denoting the sender identity whose
               authorization should be checked.  This is a domain name for the
               "helo" scope, and an e-mail address for the "mfrom" and "pra"
               scopes.
               Note:  An empty identity must not be passed.  In the case of an
               empty "MAIL FROM" SMTP transaction parameter, you should
               perform a check with the "helo" scope instead.
           ip_address
               Required for checks with the "helo", "mfrom", and "pra" scopes.
               Either a string or a NetAddr::IP object denoting the IP address
               of the host claiming the identity that is being checked.  Can
               be either an IPv4 or an IPv6 address.  An IPv4-mapped IPv6
               address (e.g. '::ffff:192.168.0.1') is treated as an IPv4
               address.
           helo_identity
               A string denoting the "HELO" SMTP transaction parameter in the
               case that the main identity is of a scope other than "helo".
               This identity is then used merely for the expansion of "%{h}"
               macros during the policy evaluation of the main identity.
               Defaults to undef, which will be expanded to 'unknown'.  If the
               main identity is of the "helo" scope, this option is unused.
       new_sub_request(%options): returns Mail::SPF::Request
           Must be invoked on an existing request object.  Creates a new sub-
           request object by cloning the invoked request, which is then
           considered the new request's super-request.  Any specified options
           (see the "new" constructor) override the parameters of the super-
           request.  There is usually no need to specify any options besides
           the "authority_domain" option.
   Instance methods
       The following instance methods are provided:
       root_request: returns Mail::SPF::Request
           Returns the root of the request's chain of super-requests.
           Specifically, returns the request itself if it has no super-
           requests.
       super_request: returns Mail::SPF::Request
           Returns the super-request of the request, or undef if there is
           none.
       versions: returns list of string
           Returns a list of the SPF record versions that are used for
           request.  See the description of the "new" constructor's "versions"
           option.
       scope: returns string
           Returns the scope of the request.  See the description of the "new"
           constructor's "scope" option.
       authority_domain: returns string
           Returns the authority domain of the request.  See the description
           of the "new" constructor's "authority_domain" option.
       identity: returns string
           Returns the identity of the request.  See the description of the
           "new" constructor's "identity" option.
       domain: returns string
           Returns the identity domain of the request.  See the description of
           the "new" constructor's "identity" option.
       localpart: returns string
           Returns the identity localpart of the request.  See the description
           of the "new" constructor's "identity" option.
       ip_address: returns NetAddr::IP
           Returns the IP address of the request as a NetAddr::IP object.  See
           the description of the "new" constructor's "ip_address" option.
       ip_address_v6: returns NetAddr::IP
           Like the "ip_address" method, however, an IPv4 address is returned
           as an IPv4-mapped IPv6 address (e.g. '::ffff:192.168.0.1') to
           facilitate uniform processing.
       helo_identity: returns string
           Returns the "HELO" SMTP transaction parameter of the request.  See
           the description of the "new" constructor's "helo_identity" option.
       record: returns Mail::SPF::Record
           Returns the SPF record selected during the processing of the
           request, or undef if there is none.
       state($field): returns anything
       state($field, $value): returns anything
           Provides an interface for storing temporary state information with
           the request object.  This is primarily meant to be used internally
           by Mail::SPF::Server and other Mail::SPF classes.
           If $value is specified, stores it in a state field named $field.
           Returns the current (new) value of the state field named $field.
           This method may be used as an lvalue.
