为什么我的 PHP `mail()` 函数电子邮件最终会进入垃圾邮件文件夹？

PHP 上邮件函数将电子邮件发送到垃圾邮件的疑难解答

通过 PHP 的 mail() 函数发送电子邮件时，它们经常会进入垃圾邮件文件夹。要解决这个问题，我们必须了解根本问题。

解决这个问题的关键在于mail()函数没有使用配置良好的SMTP服务器。例如：

$ticketDetail is an array containing pertinent information for transmission.
sendOwnershipEmail('[email protected]', $ticketDetail);

function sendOwnershipEmail($email, $ticketDetail) {
    $param = new stdClass();
    
    $param->content = "<div>
        <div><b>".$ticketDetail[0]['ticket_number']."</b></div>
<br>
        <div><img  src="%22.%24ticketDetail%5B0%5D%5B" image_path alt="为什么我的 PHP `mail()` 函数电子邮件最终会进入垃圾邮件文件夹？" ></div>
<br>
        <div>Ticket with ticket number ".$ticketDetail[0]['ticket_number']." has been requested for tranfer from <div></div>
        <div>".$ticketDetail[0]['oldDepartment']." to ".$ticketDetail[0]['newDepartment']." Department <div></div>
      </div>";
    
    $param->sendTo = $email;
    $param->subject = "Request for Department transfer";
    
    sendMailFunction($param);
}

function sendMailFunction($param) {
        $to = $param->sendTo;
        $subject = $param->subject;
        $headers = 'MIME-Version: 1.0' . "\r\n";
        $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
        $headers .= 'From: [email protected]' . "\r\n";
        $message = "" .
               "<meta http-equiv="Content-Language" content="en-us">" .
               "<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">" .
               "" .$param->content.       
               "<br><br>";
    mail($to, $subject, $message, $headers);
