Question

我试图通过PHPMailer发送电子邮件。出于某种原因，我不明白认证失败了。

我也尝试了不同的设置，比如将设置验证设置为PLAIN，将安全方法设置为TLS，但它似乎没有帮助。

我们的Exchange有一个发送连接器，它将电子邮件发送到我们的垃圾邮件代理，它将邮件发送到邮件服务器，邮件服务器使用DKIM加密邮件。

这是我的代码：

$mail = new PHPMailer();

        $mail->IsSMTP();                                      // set mailer to use SMTP
        $mail->Host = $settings['mailserver'];  // specify main and backup server
        $mail->SMTPAuth = true;     // turn on SMTP authentication
        $mail->Port = "25";
        $mail->Username = $settings['mail_domain']."\\".$settings['mail_username'];  // SMTP username
                    echo $mail->Username;
        $mail->Password = $settings['mail_password']; // SMTP password
        $mail->SMTPOptions = array(
            'ssl' => array(
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
            )
        );

                    $mail->SMTPDebug = 2;

        $mail->From = $settings['mail_sender'];
        $mail->AddAddress($emp_mail);           // name is optional
        $mail->AddReplyTo($settings['mail_sender']);

        $mail->WordWrap = 50;                                 // set word wrap to 50 characters
        //$mail->AddAttachment("/var/tmp/file.tar.gz");         // add attachments
        $mail->IsHTML(true);                                  // set email format to HTML

        $mail->Subject = "Neue Datei erhalten: ".$filename." - ".$_COOKIE['settings']['firmenname'];
        $mail->Body    = $text;
        $mail->AltBody = "Bitte laden Sie diese Email in der HTML Ansicht";

        if(!$mail->Send())
        {
            $return_code['Code'] = 500;
            $return_code['Msg'] = $mail->ErrorInfo.print_r($settings);
        }else{
            $return_code['Code'] = "200";
        }

这是我的答案：

任何想法？

Answer 1

经过一些研究后我发现，这实际上是一个cPanel问题！似乎cPanel正在将传出SMTP连接重定向到自己的本地邮件服务器。

中可以禁用此选项

在cPanel根面板中。我只是没想到，因为我看到服务器响应。我只是没有意识到，它是自己的Web服务器邮件服务器，正在响应
