PHPMailer似乎不适用于主机托管

Question

我在核心PHP上使用PHPMailer和主机托管业务帐户，我在SMTPDebug中得到了以下错误：

2020-01-13 13:16:54 SERVER -> CLIENT: 220-gator4001.hostgator.com ESMTP Exim 4.92 #2 Mon, 13 Jan 2020 07:16:54 -0600 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

日志的第一行说，我们不授权使用此系统来传输未经请求的、220和/或批量电子邮件。但与此同时，PHPMailer给了我邮件发送给的回复。

，这里的问题是什么，我该如何解决？

另外，我没有使用my@emailaddress.com和domainname.com，而是使用了实际的电子邮件地址和实际的网站地址。只是写在这里，显然人们指出了这里最奇怪的东西。

编辑

请查找下面的php代码：

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'Exception.php';
require 'PHPMailer.php';
require 'SMTP.php';


$mail = new PHPMailer(true);                              
try {
    //Server settings
    $mail->SMTPDebug = 2;
    $mail->isSMTP();
    $mail->Host = 'domainname.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'donotreply@domainname.com';
    $mail->Password = 'mypassword';
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;
    //Recipients
    $mail->setFrom('donotreply@domainname.com', 'MyTestEmail');
    $mail->addAddress('info@domainname.com', 'Khan');

    //Content
    $mail->isHTML(true);
    $mail->Subject = 'Test Email body';
    $mail->Body    = 'Test Email body';
    $mail->AltBody = 'Test Email body';

    $mail->send();
    return "SUCCESS";
} catch (Exception $e) {
    return "FAIL";
    // Use the line below to display error
    // echo 'Mailer Error: ' . $mail->ErrorInfo;
}   

?>

**更新**

我在donotreply@domainname.com上收到了回弹的电子邮件，错误如下：

The mail system

Answer 1

问题主要与新创建的电子邮件donotreply@domainname.com本身有关。使用PHPMailer测试的前两个电子邮件地址在收件箱中反弹回来。如果您所面临的问题与我本人完全相同，那么我建议您进行以下故障排除：

确保未将Debug设置为0

$mail->SMTPDebug =2

测试您的代码，并检查PHPMailer最终是否成功。

检查PHPMailer是否回显成功

正如@ADyson所指出的，下面的错误/通知并不意味着不工作PHPMailer。

服务器->客户端: 220-gator4001.hostgator.com ESMTP Exim 4.92 #2 Mon，2020年1月13日07:16:54-0220-我们不授权使用该系统传输未经请求的220和/或批量电子邮件。

其次，通过向不同服务器上的不同域发送电子邮件来测试代码。

测试发送电子邮件到Gmail，Hotmail，雅虎，其他电子邮件托管在另一个服务器上。

检查您的收件箱是否有任何回弹的信息。

如果您收到了一条回弹消息，

；可以肯定的是，PHPMailer工作正常。

与您的主机联系，以获得更多详细信息，向他们提供错误的详细信息，在反弹的电子邮件。

我的问题被hostgator解决了，因为发送到几个电子邮件地址的电子邮件会反弹回来，而Gmail和Hotmail都能很好地工作。
