$this->db->insert('iv_mail',$data);
$insert_id=$this->db->insert_id();
foreach($this->input->post('features') as $feature){
$data=array('mail_id'=>$insert_id,
'featurename'=> $feature);
$this->db->insert('iv_mail_features',$data);

You must do name all checkbox as an array like this.
<input type="checkbox" name="checkbox[]" value="add"><hr>
<input type="checkbox" name="checkbox[]" value="edit"><hr>
<input type="checkbox" name="checkbox[]" value="update"><hr>
<input type="checkbox" name="checkbox[]" value="delete">
then in your function must be like this
$inputnum = count($this->input->post('checkbox'));
for ($i=0;$i < $inputnum; $i++) {
echo $this->input->post('checkbox')[$i].'<hr>';
}
You can change the code as you want.
also, you can add all features as json in one column like this
$inputnum = count($this->input->post('checkbox'));
for ($i=0;$i < $inputnum; $i++) {
$checkbox[] = $this->input->post('checkbox')[$i].'<hr>';
}
json_encode($checkbox);
