为什么这封邮件直接进入垃圾邮件箱？

Question

我使用下面的脚本来发送邮件

<? 
extract($_POST); 
$subject = "Feedback from ".$name." (".$email.", Ph: ".$phone.")"; 
$mail = @mail($send,$subject,$content); 
if($mail) { echo "Your feedback has been sent"; } 
else { echo "We are sorry for the inconvienience, but we could not send your feedback now."; } 
?> 

但这总是在垃圾邮件文件夹结束了。为什么？

Answer 1

您必须在发送邮件时使用邮件头，以证明邮件是从真实来源而非机器人到达的。

试试这个！

<? 
    extract($_POST); 
    $subject = "Feedback from ".$name." (".$email.", Ph: ".$phone.")"; 
    $headers = 'MIME-Version: 1.0' . "\r\n"; 
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; 
    $headers .= 'From:'.$email."\r\n"; 
    $headers .= 'Reply-To: '.$email; 
    $mail = @mail($feedback,$subject,$content,$headers); 
    if($mail) { echo "Your feedback is send"; } 
    else { echo "We are sorry for the inconvienience, but we could not send your feedback now."; } 
?>
