NAME

Mail::DMARC::opendmarc - Perl extension wrapping OpenDMARC's libopendmarc library

SYNOPSIS

  use Mail::DMARC::opendmarc;

  my $dmarc = Mail::DMARC::opendmarc->new();

  # Get spf and dkim auth results from Authentication-Results (RFC5451) header
  # Store them into the dmarc object together with from domain and let object
  # query DNS too
  $dmarc->query_and_store_auth_results(
        'mlu.contactlab.it',  # From: domain
        'example.com',  # envelope-from domain
        Mail::DMARC::opendmarc::DMARC_POLICY_SPF_OUTCOME_NONE, # SPF check result
        'neutral', # human-readable SPF check result
        'mlu.contactlab.it', # DKIM domain
        Mail::DMARC::opendmarc::DMARC_POLICY_DKIM_OUTCOME_PASS, # DKIM check result
        'ok' # human-readable DKIM check result
                );
                
  my $result = $dmarc->verify();
  
  # result is a hashref with the following attributes:
  #             'spf_alignment' 
  #             'dkim_alignment'
  #             'policy'
  #             'human_policy' 
  #             'utilized_domain'

  print "DMARC check result: " . $result->{human_policy} . "\n";
  
  # Diagnostic output of internal libopendmarc structure via this handy function:
  print $dmarc->dump_policy() if ($debug);
  # Use it often. Side-effects on the library's internal structure might
  # interfere if you're trying to optimize call sequences.
  
  if ($result->{policy} == Mail::DMARC::opendmarc::DMARC_POLICY_PASS)
                ...
