适用于 Gmail.com 和带附件的多部分/混合邮件!
<?php
// Send simple email without DKIM SIgning
// YOUR E-MAIL
$name = 'Name Jony';
$sender = 'sdsdso@domain.pl';
$to = 'ffffu@gmail.com';
$subject = 'Simple html message with dkim';
$headers =
'MIME-Version: 1.0
From: "'.$name.'" <'.$sender.'>
Content-type: text/html; charset=utf8';
$message =
'<html>
<header></header>
<body>
Hello, this a DKIM test e-mail
</body>
</html>';
// NOW YOU WILL DO (after setting up the config file and your DNS records) :
// Make sure linefeeds are in CRLF format - it is essential for signing
$message = preg_replace('/(?<!\r)\n/', "\r\n", $message);
$headers = preg_replace('/(?<!\r)\n/', "\r\n", $headers);
require_once 'mail-signature.class.php';
require_once 'mail-signature.config.php';
$signature = new mail_signature(
MAIL_RSA_PRIV,
MAIL_RSA_PASSPHRASE,
MAIL_DOMAIN,
MAIL_SELECTOR
);
$signed_headers = $signature -> get_signed_headers($to, $subject, $message, $headers);
// Send email
ini_set('sendmail_from', $sender);
echo mail($to, $subject, $message, $signed_headers.$headers);
die();
