Question

我收到以下错误：身份验证凭据无效。

我已经两次检查用户名（访问密钥ID）和密码（密钥令牌）一百万次。我仔细检查了发送到服务器的base64并且它是正确的。用户具有正确的访问权限。允许来自EC2服务器的所有出站流量。 SELinux被禁用。我已经逃脱了特殊角色，尝试了不同的凭据。尝试使用具有更多访问权限的用户。

我正在将PHPMailer与AWS SES结合使用。

以下是代码：

$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'tls';
$mail->SMTPDebug = 4;
$mail->setFrom('braydenrhancock@gmail.com', 'Sender Name');
$mail->addAddress('braydenrhancock@gmail.com', 'Recipient Name');
$mail->Username = 'AKIAINH6PZ2UQKDK2BTA';
$mail->Password = 'GvMMa7R3fAXZGacl3gyfA86J0RxJLO7FQte9vrof';
$mail->Host = 'email-smtp.us-east-1.amazonaws.com';
$mail->Subject = 'Amazon SES test (SMTP interface accessed using PHP)';
$mail->Body = '<h1>Email Test</h1>';
$mail->Port = 587;
$mail->isHTML(true);
$mail->AltBody = "Email Test\r\nThis email was sent through the 
    Amazon SES SMTP interface using the PHPMailer class.";

if(!$mail->send()) {
    echo "Email not sent. " , $mail->ErrorInfo , PHP_EOL;
} else {
    echo "Email sent!" , PHP_EOL;
}

以下是完整输出：

SES不支持使用IAM用户访问键发送电子邮件。 SES使用Amazon SES SMTP凭证。

Sign in to the AWS Management Console and open the Amazon SES console at https://console.aws.amazon.com/ses/.

In the navigation pane, choose SMTP Settings.

In the content pane, choose Create My SMTP Credentials.

In the Create User for SMTP dialog box, you will see that an SMTP user name has been filled in for you. You can accept this suggested user name or enter a different one. To proceed, choose Create.

Choose Show User SMTP Credentials. Your SMTP credentials will be displayed on the screen; copy them and store them in a safe place. You can also choose Download Credentials to download a file that contains your credentials.

以下是文档的链接，该文档说明了不同类型的凭据以及它们如何与SES一起使用。

这些是您的AWS凭据还是SMTP凭据？如果这些是AWS凭据，则生成SMTP凭据，然后尝试。 See it here

Answer 3

此示例函数适用于在Windows 2012上安装了PHP 7.1的Amazon SES，假设您将phpmailer 5.2（或左右）解压缩到我所做的相同位置。我没有打扰作曲家。注意在下面的函数中我注释掉了这一行 $ mail-＆gt; SMTPDebug = 2; ...但是你想在测试时取消评论这一行，这样你就可以看到发生了什么。您需要添加的值在括号内。我的SES主持人是＆＃34; email-smtp.us-east-1.amazonaws.com＆＃34; ，只要确保你使用的任何一个，你不会放任何东西，而不仅仅是东道主fqdn，没有别的东西（不要带tls：// ....

将以下内容另存为Send_Amazon_Mail.php

<?php 
function Send_Mail($to,$subject,$body)
{
require 'C:\Program Files\PHP\v7.1\phpmailer\PHPMailerAutoload.php';
$from = "[SES validated email address here]";
$mail = new PHPMailer();
// $mail->SMTPDebug = 2;
$mail->IsSMTP(true); // SMTP
$mail->SMTPAuth   = true;  // SMTP authentication
$mail->SMTPSecure = 'ssl';
$mail->Mailer = "smtp";
$mail->Host= "[your SES host]";
$mail->Port = 465;  // SMTP Port
$mail->Username = "[SES SMTP USERNAME]";  // SMTP  Username
$mail->Password = "[SES SMTP PASSWORD]";  // SMTP Password
$mail->SetFrom($from, 'Test Do Not Reply');
$mail->AddReplyTo($from,'[SES validated email address here]');
$mail->Subject = $subject;
$mail->MsgHTML($body);
$address = $to;
$mail->AddAddress($address, $to);

if(!$mail->Send())
return false;
else
return true;

}
?>

您可以使用测试程序调用此函数

<?php
require 'Send_Amazon_Mail.php';
$to = "[someemailaddresshere]";
$subject = "Test Mail Subject";
$body = "Hi<br/>Test Mail<br/>Amazon SES"; // HTML  tags
Send_Mail($to,$subject,$body);
?>

Answer 4

我在这里添加了我的答案，因为上方没有任何帮助。此问题与WHM / cPanel中的安全功能有关。仅在服务器上装有WHM时阅读更多内容。

该选项称为：

将传出SMTP限制为root，exim和mailman（FKA SMTP调整）

如果禁用此功能，则问题已解决。请记住，在某些版本的cPanel上缺少此选项，它会出现在WHM中，因为它会影响所有帐户。对我来说，可以禁用它，因为我是服务器的所有者，并且那里没有未知的域/用户。

Answer 5

我遇到了同样的问题，直到我发现ConfigServer安全和防火墙（csf）由于某种原因阻止了它。我重新启动了csf服务，此问题已自行解决。
