Question

这是我用来从网站上的联系表单发送电子邮件的完整代码。尽管使用了所有最佳实践（标题等），但结果如下：

1）向用户发送的确认电子邮件每次都会收到垃圾邮件，并且会被视为网络钓鱼

2）管理员电子邮件被标记为网上诱骗

有人可以帮助我吗？谢谢！

Answer 1

您需要使用标头。这对我有用：

$to = "mail@example.com";
$subject = "your subject";
$body = "<p>Your Body</p>";
$headers  = "From: Sender Name <mail2@example.com>" . "\r\n";
$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
mail($to, $subject, $body, $headers);

此外，您可以在注册商处为您的域名添加TXT Record SPF。转到DNS设置并添加以下TXT记录：

输入：TXT
主持人：example.com
价值：v=spf1 ip4:YOUR.SERVER.IP.HERE ~all
TTL：Automatic

这用于验证邮件是否已被欺骗。

Answer 2

您无法明确控制您的电子邮件是否被标记为垃圾邮件，但您可以采取一些措施来提供帮助。

确保您的反向DNS正确无误。
实施SPF。
实施DKIM。
在本地安装SpamAssassin并通过详细模式运行您的邮件样本，以了解他们可能会被标记的原因。
使用MailChimp或MailGun等服务代替本地送货员。
