Google Form Email Notification On Submission - email

Question

I'm trying to update this script to allow me to update the "Sender's" or "Reply To" email address. I'm unsure how to do this as I'm using the script listed here - http://www.labnol.org/?p=20884
I've emailed the developer of this script but have yet to receive a response. Any advice on adding a field to overwrite the default "Reply To" or sender email address?
Thanks for your help!

function Initialize() {
var triggers = ScriptApp.getScriptTriggers();
for(var i in triggers) {
ScriptApp.deleteTrigger(triggers[i]);
}
ScriptApp.newTrigger("SendGoogleForm")
.forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
.onFormSubmit()
.create();
}
function SendGoogleForm(e)
{
try
{
// You may replace this with another email address
var email = "CLIENT EMAIL ADDRESS";
// Optional but change the following variable
// to have a custom subject for Google Form email notifications
var subject = "Form Application Submitted";
var s = SpreadsheetApp.getActiveSheet();
var columns = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];
var message = "";
// Only include form fields that are not blank
for ( var keys in columns ) {
var key = columns[keys];
if ( e.namedValues[key] && (e.namedValues[key] != "") ) {
message += key + ' :: '+ e.namedValues[key] + "\n\n";
}
}
// This is the MailApp service of Google Apps Script
// that sends the email. You can also use GmailApp for HTML Mail.
MailApp.sendEmail(email, subject, message);
} catch (e) {
Logger.log(e.toString());
}
}

Replace
MailApp.sendEmail(email, subject, message);
with
GmailApp.sendEmail(email, subject, message, {replyTo: "abc#example.com", from: "xyz#example.com"});
The from address has to be an alias though.
