Mail::DKIM(3p)

NAME
Mail::DKIM - Signs/verifies Internet mail with DKIM/DomainKey signatures

SYNOPSIS
  # verify a message
  use Mail::DKIM::Verifier;

  # create a verifier object
  my $dkim = Mail::DKIM::Verifier->new();

  # read an email from stdin, pass it into the verifier
  while (<STDIN>)
  {
      # remove local line terminators
      chomp;
      s/\015$//;

      # use SMTP line terminators
      $dkim->PRINT("$_\015\012");
  }
  $dkim->CLOSE;

  # what is the result of the verify?
  my $result = $dkim->result;

DESCRIPTION
This module implements the various components of the DKIM and DomainKeys message-signing and verifying standards for Internet mail. It currently tries to implement these specifications:

RFC4871, for DKIM
RFC4870, for DomainKeys

The module uses an object-oriented interface. You use one of two different classes, depending on whether you are signing or verifying a message. To sign, use the Mail::DKIM::Signer class. To verify, use the Mail::DKIM::Verifier class. Simple, eh?

KNOWN BUGS
Problems passing `make test' seem to usually point at a faulty DNS configuration on your machine, or something weird about your OpenSSL libraries.

The "author signing policy" component is still under construction. The author signing policy is supposed to identify the practice of the message author, so you could for example reject a message from an author who claims they always sign their messages. See Mail::DKIM::Policy.
