Mail::DKIM(3) 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.
