tel is an alias of the count(*) function so you won't have to do $row->count(*), i don't think it will work.

To make a callback function you have to define the message.

Code:

function _checkEmailAddress($str) // start with an underscore to make function invisible for the routing
{
   $query = $this->db->query("SELECT count(*) tel FROM users WHERE emailAddress = ?",array($emailAddress));
   $row = $query->row();
   if ($row->tel == 0)
   {
      $this->validation->set_message('_checkEmailAddress', 'The %s field doesn't exist in our database');
      return false;
   }
   else
   {
      return true;
   }
}
// to add to the rules
$rules['emailAddress']    = "required|valid_email|callback__checkEmailAddress"; // two underscores
