通过 Zend Mail 发送邮件未通过 DKIM 签名并在 qq.com 中变成垃圾邮件

Question

我正在努力使用 ZF2 发送电子邮件。问题是它们在我测试过的其他邮件客户端中都运行良好，但在 qq.com 中，所有邮件都会进入垃圾邮件文件夹。这是我用来发送邮件的代码：

$mailTransportModel = $sl->get('MailTransportModel');

$transport = $mailTransportModel->getMailTransport($parameters['api_key']);
$messageIdHost = $config['mailServers'][$parameters['api_key']]['messageIdHost'];

$mail = new Zend\Mail\Message();
$mail->addTo($parameters['to'])
    ->setFrom($parameters['from_email'], $parameters['from_name'])
    ->setSubject(CommonLib::assignTemplateVariables($parameters['template']['subject'], $parameters['context_variables']));

if(!empty($parameters['replyto_email'])) {
    if(!empty($parameters['replyto_name'])) {
    $mail->addReplyTo($parameters['replyto_email'], $parameters['replyto_name']);
    } else {
    $mail->addReplyTo($parameters['replyto_email']);
    }
}

$headers = $mail->getHeaders();

$messageId = sha1($config['salt'] . microtime());
$headers->addHeaderLine('Message-Id', "<" . $messageId . "@" . $messageIdHost . ">");

$html = new Part(CommonLib::assignTemplateVariables($parameters['template']['body'], $parameters['context_variables']));

$body = new Zend\Mime\Message();

// Create HTML part
$html          = new Part(CommonLib::assignTemplateVariables($parameters['template']['body'], $parameters['context_variables']));
$html->type    = Mime::TYPE_HTML;
$html->charset = 'utf-8';

// Create plain text part
$stripTagsFilter   = new \Zend\Filter\StripTags();
$textContent       = str_ireplace(array("<br />", "<br>"), "\r\n", CommonLib::assignTemplateVariables($parameters['template']['body'], $parameters['context_variables']));
$textContent       = $stripTagsFilter->filter($textContent);
$textPart          = new Zend\Mime\Part($textContent);
$textPart->type    = Mime::TYPE_TEXT;

// Create separate alternative parts object
$alternatives           = new Zend\Mime\Message();
$alternatives->setParts(array($textPart, $html));
$alternativesPart       = new Zend\Mime\Part($alternatives->generateMessage());
$alternativesPart->type = Mime::MULTIPART_ALTERNATIVE . "; \n boundary=\"" . $alternatives->getMime()->boundary() . "\"";
$body->addPart($alternativesPart);
$mail->setBody($body);
$mail->setEncoding("UTF-8");

$headers->get('content-type')->setType('multipart/alternative');

$transport->send($mail);

这里是收到的邮件中的示例 header：

Received-SPF: pass (google.com: domain of something@something.com designates OTHERIP as permitted sender) client-ip=OTHERIP;
Message-ID: <551d5394.4164c20a.5989.fffff01fSMTPIN_ADDED_BROKEN@mx.google.com>
Date: Thu, 02 Apr 2015 17:35:01 +0300
To: CUSTOMER_EMAIL
From: =?UTF-8?Q?SOMETHING.COM?= <something@something.com>
Subject: =?UTF-8?Q?Daily=20Statement?=
MIME-Version: 1.0
Content-Type: multipart/alternative;
 boundary="=_c802aad96623e4d95c320e2cbceca602"
Content-Transfer-Encoding: =?UTF-8?Q?8bit?=
Sender: 

This is a message in Mime Format.  If you see this, your mail reader does not support this format.

--=_c802aad96623e4d95c320e2cbceca603
Content-Type: text/plain
Content-Transfer-Encoding: 8bit

<SOME HTML THINGS HERE>

--=_c802aad96623e4d95c320e2cbceca603--

我注意到 DKIM 签名失败了...我怀疑它可能来自空的发件人：header 行，但我尝试了一些方法但 none 可以将其删除.. .

提前致谢！

Answer 1

哇，我终于找到了解决问题的方法。事实证明，我的 ZF2 版本太旧了。实际上是2.2.4。问题是，在我将电子邮件消息传递给传输之后，Zend 在内部（Smtp.php class、准备Headers() 函数）克隆了 Headers object并且出于某种原因，删除了 Bcc header。不仅如此，它还添加了空的 Sender header（因为我没有在客户端代码中为它设置任何值）。因此，在将消息传递给 Postfix 后，它有一个空的发件人：header，它无法在 DKIM-filter 中解析。 PHP-side 解决方案是在构建消息本身时为发件人添加一个值：header：

$mail->addTo($parameters['to'])
    ->setFrom($parameters['from_email'], $parameters['from_name'])
    ->setSubject(CommonLib::assignTemplateVariables($parameters['template']['subject'], $parameters['context_variables']))
    ->setSender($parameters['from_email'], $parameters['from_name']);

最后一点是让 DKIM-filter 知道发送电子邮件的主机是可信的。

我花了很长时间才弄明白这一点。我希望它对其他人有用:)
