NAMEMail::DKIM::AuthorDomainPolicy - represents an Author Domain Signing Practices (ADSP) record
DESCRIPTIONThe Author Domain Signing Policies (
The record is published as a
More details about this record can be found by reading the specification itself at <tools.ietf.org/html/rfc5617>.
my $policy = Mail::DKIM::AuthorDomainPolicy->fetch( Protocol => "dns", Author => 'firstname.lastname@example.org', );
new()Construct a default policy object.
my $policy = Mail::DKIM::AuthorDomainPolicy->new;
my $policy = Mail::DKIM::AuthorDomainPolicy->parse( String => "dkim=all", Domain => "aaa.example", );
apply()Apply the policy to the results of a
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. It can be considered very suspicious.
- The message is neither approved nor rejected by the sender signing policy. It can be considered somewhat suspicious.
Note: in the future, these values may become:
none - no
pass - a passing signature is present
nxdomain - the
temperror - transient error occurred
permerror - non-transient error occurred
is_implied_default_policy()Tells whether 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()Tells 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,
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:
- The default. The entity may sign some or all email.
- 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.
- 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 discarded by the recipient's mail server.
The domain is out of scope, i.e., the domain does not exist in the
signall()True if policy is ``all''.
signall_discardable()True if policy is ``strict''.
Section 4.3 of the specification says to perform a query on the
domain itself just to see if it exists. This class is not
currently doing that, i.e. it might report NXDOMAINbecause _adsp._domainkey.example.org is nonexistent, but it should not be treated the same as example.org being nonexistent.
