I try to send email from our server using php and Zend_Mail. I use smtp transport. This is confimation email of subscribing. But for some reason email that I send has strange headers and email goes to spam folder (I see them in gmail that receive letter):

 Message-Id: <50ee94f7.84fc440a.62dc.ffff9685SMTPIN_ADDED_MISSING@mx.google.com>
    Received: (qmail 10943 invoked from network); 10 Jan 2013 10:16:22 -0000
    Received: from unknown (HELO searchboxindustries.com)  (username@searchboxindustries.com@207.162.215.30)

What does it mean list header "Recieved: from unknown"? Can it make email go to spam? How to avoid this strange header and make email avoid spam folder? Is there any problem with coode or maybe I have some problems with DNS settings of this domain?

Here's code for setting headers:

$mailer->setFrom($params['list_email'], $params['list_from_name']);
$mailer->setReplyTo($params['list_email']);

$mailer->addHeader('Sender', $params['list_email'] . '.searchboxindustries.com');                       
$mailer->setReturnPath($params['list_email'] . '.searchboxindustries.com');         

$mailer->addTo($params['email_address']);

Code to configure transport:

$emailConfig = $this->getOption('email');                                   
        $transport = new Zend_Mail_Transport_Smtp($emailConfig['server'], $emailConfig);
Zend_Mail::setDefaultTransport($transport);

Email config from application.ini:

   email.name  = searchboxindustries.com
   email.server = searchboxindustries.com
   email.username = user_name
   email.password = password
   email.auth = plain
   email.port = 587

Here are headers of such email:

Spf seems to be ok. The ip from which email is sent is not blacklisted.

Now there are changes in DNS and I have headers:

Message-Id: <50f41c80.67e3440a.2d32.6aabSMTPIN_ADDED_MISSING@mx.google.com>
Received: (qmail 18457 invoked from network); 14 Jan 2013 14:55:59 -0000

  by searchboxindustries.com with SMTP; 14 Jan 2013 14:55:59 -0000

We have Reverse DNS set. 207.162.215.30 is resolved to stmp1.searchboxindustries.com. What's the problem then? I wonder what is strange format in brackets in the header Received : from unknow:

 username@searchboxindustries.com@207.162.215.30

这Received: from unknown只是意味着一个 SMTP 服务器从另一个不提供反向 DNS 的 SMTP 服务器接收它。通常，从一个 SMTP 服务器到另一个 SMTP 服务器的每个跃点都会Received:在消息顶部添加一个标头（除了qmail，它添加了两个；这在您的示例中可见）。

如果您担心缺少反向 DNS，并且如果 207.162.215.30 是您的，那么也许您可以说服您的 ISP 为其提供反向 DNS。许多 ISP 拒绝（如果您使用“消费者”宽带计划），或者需要与您签订不同的托管合同才能提供此服务。（“反向 DNS”意味着当有人向 DNS 查询“207.162.215.30 的 DNS 名称是什么”时，答案将是“searchboxindustries.com”或其他主机名，但不是“未知”。）

反向 DNS 查找通常基于 TCP 标头而不是消息文本执行。如果 SMTP 服务器接收到来自 123.45.67.89 的连接，那么它将对该地址执行反向 DNS，并将结果放在Received:它添加的标头中。换句话说，您的邮件标头或信封标头的内容根本不会影响此结果。

收件人可以对这些标头做任何他们想做的事情。仅此标头（此标头的存在，或从其内容中没有明显的反向 DNS 信息）不太可能足以让某人将您的邮件分类为垃圾邮件，但实际上没有办法控制收件人使用此信息。

如果有的话，您的问题表明您可能应该寻求专业服务来代表您发送这些消息，但需要付费。

我的服务器需要额外的 (php.)ini 设置，这可以解决您的问题吗？

ini_set('sendmail_from', 'enterAValidEmailAddr@yourDomainHere');

尝试以下选项以找出问题所在：

  1. 电子邮件有正文吗？我相信有电子邮件正文。
  2. 为了隔离问题，您可以尝试使用另一种替代 SMTP（例如：gmail smtp）。
  3. 或者，您可以不使用 smtp 直接使用 PHP 邮件。
