Mail::SPF::Mech::MX(3)               User Contributed Perl Documentation              Mail::SPF::Mech::MX(3)



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

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

   Constructors
       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.

   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 'mx'.

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

   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 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.
