So, here is how to implement this solution:

==== File to be modified: index.php ====

STEP 1: Add the following function right above the "sendsubmitnotification" function:

function extractemailaddress($address) // by Michael Milette (2010-10-27)

// eliminate everything outside of and including square brackets, if applicable
$start = strpos($address,'[');
if ($start > 0 && $start < strlen($address))
$end = strpos($address,']',$start+1);
if ($start > 0 && $start+1 < $end-1)
$address = substr($address,$start+1,$end-$start-1);


// Decode back to string if the email address is hex encoded
if (ctype_xdigit($address))
$address = preg_replace('#(\w)(\w)#e', "chr(hexdec('$1$2'))", $address);

// replace (at) with @, the (dot) with . and remove all spaces
$address = str_replace('(at)','@',$address);
$address = str_replace('(dot)','.',$address);
$address = str_replace(' ','',$address);

return $address;

STEP 2: modify the "sendsubmitnotification" function by adding in $ert=extractemailaddress($ert); as follows:

//Now check each of the email addresses that they are valid before creating/adding to the $emailresponseto array
foreach($emailresponsetos as $ert)

$ert=extractemailaddress($ert);
if(validate_email($ert))

$emailresponseto[]=$ert;



That's it. You could also add a tool somewhere on the webpage to help users encode email addresses. Here is a simple Javascript function I wrote to do the encoding:

// Convert characters in a string of text to hexadecimal string
function String2Hex(txtString)
var hex = '';
for(var i=0;i
