Why u want to force user for a specif type(min. 4 char) of email-id. Bcz, email-id is it self a unique address.
Any way, if u want to restrict user for 4 character email id then i think this validation rule will help u...

Code:
$this->form_validation->set_rules('username', 'Username', 'required|min_length[4]');

Think you should have a good read of the user guide about form validation but heres a step in the right direction. hope it helps you along the way

Controller

Code:
&lt;?php

class Inloggen extends Controller {

    //note your class names shoudl start with an uppcase CHAR ie In

    function Inloggen() {

        parent::Controller();

        //maybe think about autoloading these helpers

        $this->load->helper(array('form', 'url'));

        $this->load->library('form_validation');

    }

    function index() {

        $this->load->view('login');

    }

    function post() {

        //not sure what your intention is here

        $this->input->post('gebruiker');

        $this->input->post('password');

    }

    function valideer() {

        //you can save your validation rules one of two ways,

        //as a config file called form_validation (see user guide)

        //or by setting them individually in your controller. like so....

        //the names specified in the rules should relate to the name fields of your

        // form inputs

        $this->form_valdiation->set_rules('username', 'Username', 'required|max_length[12]|min_length[5]');

        $this->form_validation->set_rules('password', 'Password', 'required');

        if ($this->form_validation->run() == FALSE) {

            //if the form validation returns false, ie has errors reload the view

            //so we can display the errors

            $this->load->view('login');

        } else {

            //validate user login details against the db or something here

        }

    }

}
