Mail::SPF::Mech::MX - SPF record "mx" mechanism class

An object of class Mail::SPF::Mech::MX represents an SPF record mechanism of type "mx".

The following constructors are provided:
new(%options): returns Mail::SPF::Mech::MX
Creates a new SPF record "mx" 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::MX; throws Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMech
Creates a new SPF record "mx" mechanism object by parsing the string and any options given.

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 'mx'.
name_pattern: returns Regexp
Returns a regular expression that matches a mechanism name of 'mx'.

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 any MX hosts of the mechanism's target domain name (that is, any of the host addresses of its DNS "MX" records) 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 and 5.4, for the exact algorithm used.
