php - PHPMailer 似乎不适用于 Hostgator 托管

问题描述

我在带有 Hostgator 托管业务帐户的核心 PHP 上使用 PHPMailer，并且我在 SMTPDebug 中收到以下错误：

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.

日志的第一行显示我们不授权使用该系统来传输未经请求的 220 和/或批量电子邮件。但同时 PHPMailer 正在给我回复Mail sent。

这里可能是什么问题，我该如何解决？

此外，我使用了我的实际电子邮件地址和实际网站地址，而不是my@emailaddress.com和domainname.com 。只是在这里写这个，显然人们指出了这里最奇怪的东西哈哈。

编辑

请在下面找到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 上收到了退回的电子邮件，其中包含以下错误：

The mail system

解决方案

问题基本上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被退回。如果您面临与我完全相同的问题，那么我建议您进行以下故障排除：

确保 Debug 未设置为 0

$mail->SMTPDebug = 2

测试您的代码并检查 PHPMailer 最后是否触发成功。

检查 PHPMailer 是否回显成功

正如@ADyson 所指出的，以下错误/通知并不意味着PHPMailer 不工作。

服务器 -> 客户端：220-gator4001.hostgator.com ESMTP Exim 4.92 #2 Mon, 13 Jan 2020 07:16:54 -0600 220-我们不授权使用此系统传输未经请求的 220 和/或批量电子邮件-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您的代码

测试向托管在另一台服务器上的 Gmail、Hotmail、Yahoo、其他电子邮件发送电子邮件。

检查您的收件箱是否有任何退回的邮件。

如果您收到退回的消息；可以肯定的是 PHPMailer 工作正常。

通过在退回的电子邮件中向他们提供错误详细信息，联系您的主机以获取更多详细信息。

我的问题已由 hostgator 解决，因为发送到少数电子邮件地址的电子邮件会反弹，而它与 Gmail 和 Hotmail 完美配合
