       Mail::DKIM::Policy - abstract base class for originator "signing" policies

         # get all policies that apply to a verified message
         foreach my $policy ($dkim->policies)

             # the name of this policy
             my $name = $policy->name;

             # the location in DNS where this policy was found
             my $location = $policy->location;

             # apply this policy to the message being verified
             my $result = $policy->apply($dkim);


       Between the various versions of the DomainKeys/DKIM standards, several different forms of
       sender "signing" policies have been defined.  In order for the Mail::DKIM library to
       support these different policies, it uses several different subclasses. All subclasses
       support this general interface, so that a program using Mail::DKIM can support any and all
       policies found for a message.

       These methods are supported by all classes implementing the Mail::DKIM::Policy interface.

       Apply the policy to the results of a DKIM verifier.

         my $result = $policy->apply($dkim_verifier);

       The caller must provide an instance of Mail::DKIM::Verifier, one which has already been
       fed the message being verified.

       Possible results are:

           The message is approved by the sender signing policy.

           The message is rejected by the sender signing policy.

           The message is neither approved nor rejected by the sender signing policy. It can be
           considered suspicious.

       The policy as a string.

       Note that the string returned by this method will not necessarily have the tags ordered
       the same as the text record found in DNS.

       Is this policy implied?

         my $is_implied = $policy->is_implied_default_policy;

       If you fetch the policy for a particular domain, but that domain does not have a policy
       published, then the "default policy" is in effect. Use this method to detect when that

       Where the policy was fetched from.

       This is generally a domain name, the domain name where the policy was published.

       If nothing is published for the domain, and the default policy was returned instead, the
       location will be "undef".

       Identify what type of policy this is.

       This currently returns strings like "sender", "author", and "ADSP".  It is subject to
       change in the next version of Mail::DKIM.
