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.
