Amazon SES issue

    I’m not able to send emails with this plugin using Amazon SES. It keeps returning this error:

    CLIENT -> SERVER: EHLO example.com
CLIENT -> SERVER: STARTTLS
CLIENT -> SERVER: EHLO example.com
CLIENT -> SERVER: AUTH LOGIN
CLIENT -> SERVER: [credentials hidden]CLIENT -> SERVER: [credentials hidden]SMTP ERROR: Password command failed: 535 Authentication Credentials Invalid
SMTP Error: Could not authenticate.CLIENT -> SERVER: QUIT
SMTP Error: Could not authenticate.

    However, using phpmailer in my own PHP script, it works just fine.

    $mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->Host = "email-smtp.us-west-2.amazonaws.com";
$mail->Username = "HJSKDIOUHDSJLD";
$mail->Password = "KHSDUWHSJHSJKLSHDWUHDSJHDS";
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

    Any ideas what the issue could be? I’ve triple checked that I have the correct login / password.

    I just wanted to share a recent experience I had which I just resolved. I was getting the error 535 just like this person was. I deleted my existing Key/Secret and created a new one to ensure that I had the correct credentials. I used ss/netstat/nmap/iptables to check what ports were open or if anything was blocked, everything checked out. I used telnet to connect to the amazon smtp host, good. I sent a test email from my SES Account Dashboard, email was received. However, when I tried sending a test email from my smtp mail plugin (wp mail smtp) I kept receiving the error 535 credentials invalid. It was driving me insane! What I had to do was delete the “user” from my Identity and Access Management (IAM) and create a new user. I have no idea why I had to do this. I know I sold a website a couple months ago and my SES account had been inactive since that time but this should not have affected that user. I think something within Amazon changed in the last couple months which affected the IAM users and permissions. Hope this helps someone. I am going to post this in multiple places on the internet so search engines can pick it up.

    In order for it to work properly, you need to create your credentials in :

    Amazon SES > SMTP Settings > Create SMTP Credentials button

    If your credentials is created anywhere else it will not work – regardless if the user has the correct permissions or not.
