CodeIgniter中的AWS SMTP邮件错误（无法使用PHP SMTP发送电子邮件。您的服务器可能未配置为使用此方法发送邮件。）

Question

Am trying to send Email with AWS SMTP

auth access is passed, and configured everything but still got an error from CI

$this->load->library("email");
$config['mailtype'] = 'html';
$config['useragent']    = 'ses-smtp-user.20160628-105419'; //origon

$config['protocol']     = 'smtp';
$config['smtp_host']    = 'email-smtp.us-west-2.amazonaws.com'; //origon

$config['smtp_user']    = 'user key ';
$config['smtp_pass']    = 'password';
$config['smtp_port']    = '465';
$config['charset']  = 'utf-8';
$config['crlf'] = "
";      //should be "
"
$config['newline'] = "
";   //should be "
"
$config['wordwrap'] = TRUE;
$config['smtp_crypto'] = 'tls'; // TLS protocol
$config['email_newline'] = "
"; // SES hangs with just 


$this->email->initialize($config);

$this->email->from("email addr",'name');
$this->email->to("mail to");

$this->email->subject("test email");
$this->email->message("test!"); //메세지
$status = $this->email->send();
if($status) echo "IT WORKED!";
print_r($this->email->print_debugger());

am not sure to change 'useragent' value 'CodeIgniter' to 'ses-smtp-user.20160628-105419'

and got the following error using print_debugger() when im running this code

$config = Array(
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.googlemail.com',
    'smtp_port' => 465,
    'smtp_user' => 'xxx',
    'smtp_pass' => 'xxx',
    'mailtype'  => 'html', 
    'charset'   => 'iso-8859-1'
);
$this->load->library('email', $config);
// set new line
$this->email->set_newline("
");

//set to, from, message body, etc.
$result = $this->email->send();
