I have a problem with PHPMaile and SMTPMailer on my LARAVEL site to use Amazon SES SMTP email provider. Try to resolve or troubleshoot credential deletion and create a new method-paid credential rather than resolution. Contact Amazon Support and I was informed: the upload request is failing validation on the PHP side. When you enter my site https://sinaisdeforex.com/contact-us click the button: SEND MESSAGE is reported or error:
ErrorException (E_WARNING)
stream_socket_enable_crypto(): Peer certificate CN=`sinaisdeforex.com' did not match expected CN=`email-smtp.us-east-1.amazonaws.com'
