Email contact links are an invaluable part of any web page. However, they are also vulnerable to a particular type of web robot known as the spam harvester or spambot. A spam harvester can read through the pages in your site and extract email addresses which are then added to bulk marketing databases. RichTextEditor allows you reduce possible spam by 'disguising' a raw email address in an encoded ASCII form.. You can turn this feature off by setting this property to "false".
Example
<?php
$rte=new RichTextEditor();
$rte->Text="Type here";
$rte->EnableAntiSpamEmailEncoder=false;
$rte->ID="Editor1";
$rte->MvcInit();
echo $rte->GetString();
// use $_POST["Editor1"]to retrieve the data
?>
