$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
$config['useragent'] = 'l33t Mailer 1.0';
$config['priority'] = 5;
$this->email->initialize($config);

$this->email->from('[email protected]', 'Shopno Dinga');
$this->email->to('[email protected]');
$this->email->subject('Email Test using CI from shopno-dinga');
$this->email->message('Testing the email class from shopno-dinga.');
$this->email->send();

echo $this->email->print_debugger();
