NAME
Mail::SPF::Mech::A − SPF record "a" mechanism class
DESCRIPTION
An object of class Mail::SPF::Mech::A represents an SPF record mechanism of type "a".
Constructors
The following constructors are provided:
new(%options): returns Mail::SPF::Mech::A
Creates a new SPF record "a" mechanism object.
%options
is a list of key/value pairs representing any of the
following options:
qualifier
domain_spec
ipv4_prefix_length
ipv6_prefix_length
See "new" in Mail::SPF::Mech.
new_from_string($text,
%options): returns Mail::SPF::Mech::A; throws
Mail::SPF::ENothingToParse,
Mail::SPF::EInvalidMech
Creates a new SPF record "a" mechanism object by parsing the string and any options given.
Class
methods
The following class methods are provided:
default_qualifier
default_ipv4_prefix_length
default_ipv6_prefix_length
qualifier_pattern
See "Class methods" in Mail::SPF::Mech.
name: returns string
Returns ’a’.
name_pattern: returns Regexp
Returns a regular expression that matches a mechanism name of ’a’.
Instance
methods
The following instance methods are provided:
text
qualifier
params
stringify
domain
match_in_domain
See "Instance methods" in Mail::SPF::Mech.
domain_spec: returns Mail::SPF::MacroString
Returns the "domain−spec" parameter of the mechanism.
ipv4_prefix_length: returns integer
Returns the IPv4 network prefix length of the mechanism.
ipv6_prefix_length: returns integer
Returns the IPv6 network prefix length of the mechanism.
match($server, $request): returns boolean
Checks whether the mechanism’s target domain name (that is, any of its DNS "A" or "AAAA" host addresses) matches the given request’s IP address (see "ip_address" in Mail::SPF::Request), and returns true if it does, or false otherwise. The mechanism’s IP network prefix lengths are respected when matching address records against the request’s IP address. See RFC 4408, 5, for the exact algorithm used.
