//send email
$to = $_POST['email'];
$subject = "Welcome!";
$body = "Contains sensitive information that activates users so I've removed it.";
$additionalheaders = "From: <".SITEEMAIL.">\r\n";
$additionalheaders .= "Reply-To: ".SITEEMAIL."";
mail($to, $subject, $body, $additionalheaders);
基本上，上面的代码成功发送了一封电子邮件，并且在收件箱中显示为noreply @ mydomain，这很好，但是我注意到其他站点显示了实际名称。就像来自Facebook的消息一样，Facebook不是[email protected]。我是否缺少实现此目的的标题？
编辑以显示答案：
//send email
$to = $_POST['email'];
$subject = "Welcome!";
$body = "Contains sensitive information that activates users so I've removed it.";
$additionalheaders = "From: Name <".SITEEMAIL.">\r\n";
$additionalheaders .= "Reply-To: ".SITEEMAIL."";
mail($to, $subject, $body, $additionalheaders);
from: Jon Jones <[email protected]>
