=head1 NAME
Mail::DKIM - Signs/verifies Internet mail with DKIM/DomainKey signatures
=head1 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;
=head1 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:
=over
=item RFC4871, for DKIM
=item RFC4870, for DomainKeys
=back
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 L<Mail::DKIM::Signer> class. To verify, use
the L<Mail::DKIM::Verifier> class. Simple, eh?
=head1 SEE ALSO
L<Mail::DKIM::Signer>,
L<Mail::DKIM::Verifier>

=head1 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 L<Mail::DKIM::Policy>.
