codeigniter email bug

[eluser]Unknown[/eluser]
I have an error with the CI Email Class. It works fine on my localhost, but when I upload the project on the server, a timeout occurs. Have tried looking through the entire logic. Can someone help me out?

Code:

function contact()
    {
        $name = $this->input->post('name');
        $email = $this->input->post('email');
        $subject = $this->input->post('subject');
        $message = $this->input->post('message');

        $data['contact'] = 'contact_submitted_view';

        $config = array(
                    'protocol'=>'smtp',
                    'smtp_host'=>'xxx',
                    'smtp_port'=>465,
                    'smtp_user'=>'xxx',
'smtp_timeout'=>15,
                    'smtp_pass'=>'xxx',
                    'mailtype'=>'html'
                    );
            
        $this->load->library('email',$config);
        $this->email->set_newline("\r\n");

        // Set to, from, message, etc.
        $this->email->from('xxx');
        $this->email->to('xxx');
        $this->email->subject($subject);
        $this->email->message('Client Name:'.$name.'<br/>Client Email: '.$email.'<br/>Message:'.$message);
        if($this->input->post('ajax'))
        {
            if($this->email->send())
            {
                $this->load->view($data['contact']);
            }
            else
            {
                show_error($this->email->print_debugger());
            }
        }
        else{
            if($this->email->send())
            {
                $this->load->view('contact_submitted_view');
            }
            else
            {
                show_error($this->email->print_debugger());
            }
        }
    }

I have used ajax form submission, but the error is not with the js I'm sure of that.

Any help appreciated!!
