NAME
Mail::DKIM::Policy - represents a DKIM sender signing policy
CONSTRUCTORS
fetch() - fetch a sender signing policy from DNS
my $policy = fetch Mail::DKIM::Policy(
Protocol => "dns",
Domain => "example.org",
);If a DNS error or timeout occurs, an exception is thrown.
If the policy is not found, or a non-DNS error occurs, undef is returned instead of a policy.
new() - construct a default policy object
my $policy = new Mail::DKIM::Policy;parse() - gets a policy object by parsing a string
my $policy = parse Mail::DKIM::Policy(
String => "o=~; t=y"
);METHODS
apply() - apply the policy to the results of a DKIM verifier
Possible results are:
- accept
-
The message is approved by the sender signing policy.
- reject
-
The message is rejected by the sender signing policy.
- neutral
-
The message is neither approved nor rejected by the sender signing policy. It can be considered suspicious.
as_string() - 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.
flags() - get or set the flags (t=) tag
A vertical-bar separated list of flags.
note() - get or set the human readable notes (n=) tag
Human readable notes regarding the record. Undef if no notes specified.
policy() - get or set the outbound signing policy (o=) tag
my $sp = $policy->policy;Outbound signing policy for the entity. Possible values are:
~-
The entity signs some but not all email.
--
All mail from the entity is signed; unsigned email MUST NOT be accepted, but email signed with a Verifier Acceptable Third Party Signature SHOULD be accepted.
TODO
testing() - checks the testing flag
my $testing = $policy->testing;If nonzero, the testing flag is set on the signing policy, and the verify should not consider a message suspicious based on this policy.
BUGS
If a sender signing policy is not found for a given domain, the fetch() method should search the parent domains, according to section 4 of the dkim-ssp Internet Draft.
