首先,我对PHP并不了解。我将尝试以一种理解来解释我站点上的PHP是由一个朋友在大学为我编写的,因此我只了解其中的一小部分。无论如何,一切工作都很好,我只是想知道现在何时收到来自nf.theamitybladecom@boscustweb2204.eigbox.net的自动回复,这给我带来了哪些错误。 theamitybladecom当然是对我的网站名称的引用。我希望可以通过noreply@theamityblade.com或其他方式进行调整。无论如何,这是我到目前为止的代码,请原谅我删除了一些敏感条目。希望您能理解我的工作,并且可以轻松地对我的代码进行更改。我根本无法处理复杂的PHP,因此请以新手的术语进行解释。您能提供的任何帮助将不胜感激。谢谢

当前正在尝试使用提交者的电子邮件地址作为发件人地址:
mail("example@mysite.com",$subject,$message,"From: $email \n");
不要那样做;它是伪造的,将被阻止完全起作用,或者导致您的邮件被垃圾邮件过滤或退回。将其设置为回复标头:
mail("example@mysite.com", $subject, $message, "Reply-to: $email \n");
此代码易受标头注入攻击,因为在用作消息标头之前未对$_POST['email']
进行过滤。总体而言,避免完全使用邮件功能;本质上是不安全的。使用PHPMailer之类的库(为该问题添加了标签),然后使用SMTP将其发送到本地主机,这既快捷又安全。参见PHPMailer's contact form example。
