NAME
       Mail::DomainKeys - A perl implementation of DomainKeys

CAVEAT
       THIS MODULE IS OFFICIALLY UNSUPPORTED.

       Please move on to DKIM like a responsible Internet user.	 I have.

       I will leave this module here on CPAN for a while, just in case some-
       one has grown to depend on it.  It is apparent that DK will not be the
       way of the future. Thus, it is time to put this module to ground
       before it causes any further harm.

       Thanks for your support, Anthony

SYNOPSIS
       Mail::DomainKeys is a perl implementation of Yahoo’s mail signature
       protocol.

       This library allows one to sign and verify signatures as per draft 03
       of the DomainKeys specification:

       http://www.ietf.org/inter-
       net-drafts/draft-delany-domainkeys-base-03.txt

       A Simple Example

       This example shows the simplest possible DomainKeys signature veri-
       fier.

	 require Mail::DomainKeys::Message;

	 # load a message from a filehandle glob
	 my $mail = load Mail::DomainKeys::Message(File => \*STDIN) or
	   die "unable to load message\n";

	 # check to make sure the sender has a fully qualified domain
	 $mail->senderdomain or
	   die "unable to verify message: no sender domain\n";

	 # check if the mail is signed by DomainKeys
	 $mail->signed or
	   die "no signature\n";

	 # check the signature
	 if ($mail->verify) {
	   print STDERR "signature valid\n";
	   exit 0;
	 }

	 # the signature was not valid
	 die "unable to verify signature\n";

       This example shows the simplest possible DomainKeys signer.

	 require Mail::DomainKeys::Message;
	 require Mail::DomainKeys::Key::Private;

	 # load the message, or die trying
	 my $mail = load Mail::DomainKeys::Message(File => \*STDIN) or
	   die "unable to load message";

	 # load the private key, or die trying
	 my $priv = load Mail::DomainKeys::Key::Private(File => "private.key") or
	   die "unable to load key";

	 # sign the message using the "simple" canonifier and selector "test"
	 $mail->sign(Method => "simple", Selector => "test", Private => $priv);

	 # print out the signature
	 print $mail->signature->as_string;
