Mail::DKIM::AuthorDomUseroContributed Perl DMail::DKIM::AuthorDomainPolicy(3)



NAME
       Mail::DKIM::AuthorDomainPolicy - represents an Author Domain Signing
       Practices (ADSP) record

CONSTRUCTORS
       fetch() - lookup an ADSP record in DNS

	 my $policy = Mail::DKIM::AuthorDomainPolicy->fetch(
		   Protocol => "dns",
		   Author => ’jsmith@example.org’,
		 );

       new() - construct a default policy object

	 my $policy = Mail::DKIM::AuthorDomainPolicy->new;

METHODS
       apply() - 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:

       accept
	   The message is approved by the sender signing policy.

       reject
	   The message is rejected by the sender signing policy.  It can be
	   considered very suspicious.

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

       is_implied_default_policy() - 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 happens.

       location() - where the policy was fetched from

       If the policy is domain-wide, this will be domain where the policy was
       published.

       If the policy is user-specific, TBD.

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

       policy() - get or set the outbound signing policy (dkim=) tag

	 my $sp = $policy->policy;

       Outbound signing policy for the entity. Possible values are:

       "unknown"
	   The default. The entity may sign some or all email.

       "all"
	   All mail from the domain is expected to be signed, using a valid
	   Author signature, but the author does not suggest discarding mail
	   without a valid signature.

       "discardable"
	   All mail from the domain is expected to be signed, using a valid
	   Author signature, and the author is so confident that non-signed
	   mail claiming to be from this domain can be automatically dis-
	   carded by the recipient’s mail server.

       signall() - true if policy is "all"


       signall_discardable() - true if policy is "strict"


BUGS
       ·   If a sender signing policy is not found for a given domain, the
	   fetch() method should search the parent domains, according to sec-
	   tion 4 of the dkim-ssp Internet Draft.
