SMTP error with CodeIgniter and gmail

Question

I am using outlook.com with custom domain (eg, [email protected])

I am using code igniter Email library

Openssl is enabled

Does anyone have any idea what is going on? I have tried many solutions by others' example. it doesn't work. i have check with service provider, they doesn't block the port

the config (at config/email.php)

$config['protocol']='smtp';
$config['smtp_host']='ssl://smtp.googlemail.com';
$config['smtp_port']='587';
$config['smtp_timeout']='30';
$config['smtp_user']='[email protected]';
$config['smtp_pass']='password';
$config['charset']='utf-8';
$config['newline']='\r\n';

Here is how i send the email (at controller/test.php)

$this->load->library('email');
$this->email->from('[email protected]', 'my name');
$this->email->to('[email protected]');
$this->email->subject('test title or subject');
$this->email->message('the content');
$this->email->send();
echo $this->email->print_debugger(); 

and i got such long error message

As @SamV points out in a comment, the problem is this lines on system/libraries/Email:

$ssl = ($this->smtp_crypto === 'ssl') ? 'ssl://' : '';

$this->_smtp_connect = fsockopen($ssl.$this->smtp_host,
                        $this->smtp_port,
                        $errno,
                        $errstr,
                        $this->smtp_timeout);

If you remove the ssl:// from the smtp_host and you leave it as:

$config['smtp_host']='smtp.googlemail.com';

it will work.
