AWS SES with PHPMailer using SMTP, SMTP Error: Cou

I get the following error: Authentication Credentials Invalid.

I've double checked the username (Access key ID) and password (Secret Token) a million times. I double checked the base64 sent to the server and it's correct. User has correct access rights. All outbound traffic from EC2 server is allowed. SELinux is disabled. I've escaped special characters, tried different credentials. Tried using a user with more access.

I'm using PHPMailer with AWS SES.

Here is the code:

$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;
}

Here is the full output:

SES does not support using IAM User AccessKeys to send email. SES uses Amazon SES SMTP credentials.

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.

Here is a link to a document that explains the different type of credentials and how they are used with SES.

Using Credentials With Amazon SES

Here is a link to obtaining credentials:

回答2:

Are these your AWS credentials or SMTP credentials? And if these are AWS credentials then generate SMTP credentials and then try. See it here

Or you can try this too Similar issue

This example function will work with Amazon SES with PHP 7.1 installed on Windows 2012, assuming you unzipped phpmailer 5.2 (or so) into the same location I did. I did not bother with the composer. Note in the function below I commented out the line $mail->SMTPDebug = 2; ...but you'd want to un-comment this line while testing so you can see what happened. The values you need to add are within brackets. My SES host is "email-smtp.us-east-1.amazonaws.com" , just make sure whichever one you use that you don't put anything more than just the host fqdn, nothing else (don't lead it with tls://....

Save the following as 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;

}
?>

You can call this function with a test program

<?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);
?>
