邮件GT被Gmail标记为垃圾邮件，任何解决方案

Question

我正在使用PHP代码在我的Web应用程序中发送带有附件的邮件。 一切正常，希望Gmail将其标记为垃圾邮件。 我的代码如下所示。

move_uploaded_file($_FILES["file"]["tmp_name"],$path . $_FILES["file"]["name"]);            
        $filename = $_FILES["file"]["name"];
        //$path = "upload/";
        $from_name = $_POST['name'];
        $from_mail = $_POST['email'];
        $mailto = $replyto = "[e-mail]";
        $subject = "Resume";
        $message = $_POST['msg'];
        $to = "[e-mail]";       
        $file = $path.$filename;
        $file_size = filesize($file);
        $handle = fopen($file, "r");
        $content = fread($handle, $file_size);
        fclose($handle);
        $content = chunk_split(base64_encode($content));
        $uid = md5(uniqid(time()));
        $name = basename($file);
        $header = "From: ".$from_name." <".$from_mail.">rn";
        $header .= "Reply-To: ".$replyto."rn";
        $header .= "MIME-Version: 1.0rn";
        $header .= "Content-Type: multipart/mixed; boundary="".$uid.""rnrn";
        $header .= "This is a multi-part message in MIME format.rn";
        $header .= "--".$uid."rn";
        $header .= "Content-type:text/html; charset=iso-8859-1rn";
        $header .= "Content-Transfer-Encoding: 7bitrnrn";
        $header .= $message."rnrn";
        $header .= "--".$uid."rn";
        $header .= "Content-Type: application/octet-stream; name="".$filename.""rn"; // use different content types here
        $header .= "Content-Transfer-Encoding: base64rn";
        $header .= "Content-Disposition: attachment; filename="".$filename.""rnrn";
        $header .= $content."rnrn";
        $header .= "--".$uid."--";
        if (mail($mailto, $subject, "", $header)) {
            echo "mail send ... OK"; // or use booleans here
        } else {
            echo "mail send ... ERROR!";
        }

请帮助我

mail

（） 函数并不完全知道可以创建最完美的邮件。垃圾邮件过滤器对邮件标题非常挑剔，自己正确构建它们并非易事。最好使用SMTP库来创建具有所有重要标头的邮件（如phpmailer）

还要确保您发送邮件的服务器具有良好的IP信誉和正确的邮件设置（HELO/反向DNS等）
