NAME

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

CONTENTS

DESCRIPTION

An object of class <B>Mail::SPF::Mech::MXB> represents an SPF record mechanism of type mx.

    Constructors

The following constructors are provided:
<B>new(%options)B>: 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:
<B>qualifierB>
<B>domain_specB>
<B>ipv4_prefix_lengthB>
<B>ipv6_prefix_lengthB> See new in Mail::SPF::Mech.

<B>new_from_string($text, B>%options<B>)B>: 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:
<B>default_qualifierB>
<B>default_ipv4_prefix_lengthB>
<B>default_ipv6_prefix_lengthB>
<B>qualifier_patternB> See Class methods in Mail::SPF::Mech.
<B>nameB>: returns string Returns <B>’mx’B>.
<B>name_patternB>: returns Regexp Returns a regular expression that matches a mechanism name of <B>’mx’B>.

    Instance methods

The following instance methods are provided:
<B>textB>
<B>qualifierB>
<B>paramsB>
<B>stringifyB>
<B>domainB>
<B>match_in_domainB> See Instance methods in Mail::SPF::Mech.
<B>domain_specB>: returns Mail::SPF::MacroString Returns the domain-spec parameter of the mechanism.
<B>ipv4_prefix_lengthB>: returns integer Returns the IPv4 network prefix length of the mechanism.
<B>ipv6_prefix_lengthB>: returns integer Returns the IPv6 network prefix length of the mechanism.
<B>match($server, B>$request<B>)B>: 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 <B>trueB> if it does, or <B>falseB> 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.
