Blank page for Email test

[eluser]webnology[/eluser]
This is the code

Code:

function sendTestMail {

        $this->load->library('email');
    
        $config['protocol']  = 'smtp';
        $config['smtp_host'] = 'mailing.example.com';
        $config['smtp_user'] = 'user';
        $config['smtp_pass'] = 'pwd';
    
        $this->email->initialize($config);

        $this->email->from('[email protected]', 'Someone');
        $this->email->to('[email protected]');
        $this->email->subject('Subject');
        $this->email->message('Test');
        $this->email->send();
    }

Should be fine, no?
