Where are the SMTP settings in CodeIgniter? - codeigniter

Question

I am looking at someone else's code and need to find the SMTP details. He is using CodeIgniter however, I can not figure out where the SMTP config is being set.
For example, he is sending mail like this:
function sendMail{
$this->load->library('email');
$this->email->set_mailtype("html");
$this->email->from($this->config->item('from_email'), $this->config->item('from_name'));
$this->email->to(test#example.com);
$this->email->subject('Subject is here');
$message = "Hello";
$this->email->message($message);
$this->email->send();
return true;
}
I can not see where the config files are set. He does have the from_email item and from_name item configured in a custom config file, but that file contains only these two lines.
The default config.php does not contain anything smtp related..
Any ideas where could I find it?
Thanks!

From Codeigniter forum,
$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);
$this->email->set_newline("\r\n");
// Set to, from, message, etc.
$result = $this->email->send();

If you look in the config folder there might be a file called email.php into which default config items can be set. So they might be being set there.
These are called automatically when the email class is loaded, but can be overidden by setting them in the controller and initialising the class as described in the docs.
