PHPMailer - 邮件直接发送到垃圾邮件 [英] PHPMailer - mails going straight to spam
问题描述
每当我使用 PHPMailer 自动发送电子邮件时，它都会直接进入 Gmail 中的垃圾邮件文件夹.我曾尝试自己找到解决方案，但我对电子邮件和电子邮件标题的了解不够.
Whenever I send an automated e-mail using PHPMailer, it goes straight into the spam folder in Gmail. I have tried finding a solution to this myself but I don't know enough about e-mails and e-mail headers.
谁能解释为什么会这样?
Can anyone explain why this is happening?
PHP 代码如下，然后是从接收器显示的标题.
PHP Code is below, followed by the headers that show up from the receiver.
谢谢！
$mail = new PHPMailer;
$mail->From = "chrisxenongroup@server.xenonacademy.org.uk";
$mail->FromName = 'Xenon Group Academy';
$mail->AddAddress($email);
$mail->Subject = "Your Xenon Group Academy login details";
$mail->IsHTML(true);
$mail->Body = "<html><body><h3>Welcome to the Xenon Group Academy</h3><p>The Academy is an online system that will allow you to access course materials, manage your assignments and network with other Xenon Group students.</p>

推荐答案
这听起来更像是您的邮件服务器和/或 DNS 服务器的配置问题.您的邮件服务器似乎不够受信任"，因此您没有从 GMail(和邮件客户端)获得足够的积极"分数.我注意到您使用 postfix 作为邮件程序...您是否正确配置了它?
This does sound more like a configuration issue with your mail server and/or your DNS server. Your mail server does not appear to be "trusted" enough, so you don't get enough "positive" points from GMail (and mail clients). I notice that you're using postfix as your mailer... Have you configured it properly?
我建议你先配置 postfix.例如，以下是有关如何在 CentOS 中执行此操作的指南:
I would suggest you configure postfix first. For example, here's a guide on how to do it in CentOS:
http://wiki.centos.org/HowTos/postfix
其次，您应该将 SPF 记录添加到您的 DNS 服务器:
Second, you should add an SPF record to your DNS server:
http://en.wikipedia.org/wiki/Sender_Policy_Framework
第三，最好为您的服务器设置一个反向查找条目:
Third, it would be good to have a reverse lookup entry for your server:
http://en.wikipedia.org/wiki/Reverse_DNS_lookup
您需要执行以上操作和其他一些操作，以确保客户不会将您的邮件标记为垃圾邮件，并且您不会被列入黑名单
You will need to do the above and some more to make sure that clients don't flag your mail as spam, and you don't get blacklisted
为了避免被列入黑名单，这里有一个很好的清单:
Here's a good list of things to do to avoid getting blacklisted:
