amazon-web-services - AWS SES 与 PHPMailer 使用 SMTP，SMTP 错误 : Could not authenticate?

Question

我收到以下错误:身份验证凭据无效。

我已经仔细检查了用户名(访问 key ID)和密码( secret token )一百万次。我仔细检查了发送到服务器的base64，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。我已经转义了特殊字符，尝试了不同的凭据。尝试使用具有更多访问权限的用户。

我将 PHPMailer 与 AWS SES 一起使用。

代码如下:

$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;
}

这是完整的输出:

Answer 1

SES 不支持使用 IAM 用户访问 key 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.

这里是一个文档链接，该文档解释了不同类型的凭据以及它们如何与 SES 一起使用。
