Mail::SPF::Util is Mail::SPF's utility class.
The following class methods are provided:
Returns the fully qualified domain name (FQDN) of the local host.
Converts the specified NetAddr::IP IPv4 address into an IPv4-mapped IPv6 address. Throws a Mail::SPF::EInvalidOptionValue exception if the specified IP address is not an IPv4 address.
Converts the specified NetAddr::IP IPv4-mapped IPv6 address into a proper IPv4 address. Throws a Mail::SPF::EInvalidOptionValue exception if the specified IP address is not an IPv4-mapped IPv6 address.
Returns true if the specified NetAddr::IP IPv6 address is an IPv4-mapped address, false otherwise.
Returns the given NetAddr::IP IPv4 or IPv6 address compactly formatted as a string. For IPv4 addresses, this is equivalent to calling NetAddr::IP's addr method. For IPv6 addresses, this is equivalent to calling NetAddr::IP's short method. Throws a Mail::SPF::EInvalidOptionValue exception if the specified object is not a NetAddr::IP IPv4 or IPv6 address object.
addr
short
Returns the in-addr.arpa./ip6.arpa. reverse notation of the given NetAddr::IP IPv4 or IPv6 address. Throws a Mail::SPF::EInvalidOptionValue exception if the specified object is not a NetAddr::IP IPv4 or IPv6 address object.
in-addr.arpa.
ip6.arpa.
Finds a valid domain name for the given NetAddr::IP IP address that matches the given domain or a sub-domain thereof. A domain name is valid for the given IP address if the IP address reverse-maps to that domain name in DNS, and the domain name in turn forward-maps to the IP address. Uses the given Mail::SPF::Server and Mail::SPF::Request objects to perform DNS look-ups. Returns the validated domain name.
If $find_best_match is true, the one domain name is selected that best matches the given domain name, preferring direct matches over sub-domain matches. Defaults to false.
$find_best_match
If $accept_any_domain is true, any domain names are considered acceptable, even if they differ completely from the given domain name (which is then effectively unused unless a best match is requested). Defaults to false.
$accept_any_domain
