我正在使用PHP Mailer从我的网络服务器向用户发送邮件，但我的邮件被标记为垃圾邮件。我已经完成了我的研究，并解决了所有明显的问题：我们通过DKIM，有一个正常工作的SPF，电子邮件文本不是垃圾邮件，我们通过TLS发送。
以下是gmail标记为垃圾邮件的电子邮件标题：

Here's a message with innocuous copy.
我有一张与谷歌一起运行的支持票，他们也无法弄明白。我通过SSL连接到端口465的stmp.gmail.com：
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "myGmailAccount@gmail.com";
$mail->Password = "myGmailAccountPassword";
这是我们在dreamhost上运行的SPF：
v=spf1 ip4:208.113.210.253 include:_spf.google.com ~all
这与标题中显示的IP相同：
Received: from mysite.io (iad1-vshost51.dreamhost.com. [208.113.210.253])
我不知道我在这里缺少什么。我们是否有机会对此进行过多次测试，以至于我们实际上已经让Gmail认为邮件是垃圾邮件，只是因为我们没有将其标记为“非垃圾邮件”？
答案 0 :(得分：1)
我和你有同样的问题。我使用Gmail SMTP电子邮件回复在线商店。我的电子邮件第一次标记为垃圾邮件。但是一个月后，我要求我的朋友和我的客户将我的在线商店添加到安全列表并标记为非垃圾邮件。它不再通过垃圾邮件箱了。它也发生在雅虎。
最后，请确保您的主题和内容不会触发垃圾邮件（包含垃圾内容）。在这里查看一些垃圾话：http://blog.hubspot.com/blog/tabid/6307/bid/30684/The-Ultimate-List-of-Email-SPAM-Trigger-Words.aspx
