For basic spam protection I did set up a helper that
encodes email addresses in ASCII.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Encodes (ASCII) email addresses for basic spam protection
*
* @access public
* @param string - email address
* @param string
* @param bool
* @param string - name of css class
* @return string
*

// ------------------------------------------------------------------------
/**
* Usage Exaples:
*
* returns pure email address ASCII encoded:
* echo (encode_email('account@domain.com'));
*
* returns email address ASCII encoded with "mailto: link" and defined anchor text:
* echo (encode_email('account@domain.com','John Doe',TRUE));
*
* returns email address ASCII encoded with mailto: link, defined anchor text and css class for <a> tag:
* echo (encode_email('account@domain.com','John Doe',TRUE,'my-link-style'));

if ( ! function_exists('encode_email'))
{
function encode_email($email, $anchor_text = '', $mailto = FALSE, $css = '')
{
$email = trim($email);
$anchor_text = trim($anchor_text);
$css = trim($css);

if ($mailto === TRUE)
{
if (strlen($css) > 1)
{
$css = ' class="'.$css.'" ';
}
return '<a href="milto'.$email_encoded.'">'.$anchor_text.'</a>'. "\n";
