How can i send confirmation mail send different from address? - google-apps-script

Question

I'm sending confirmation mail with following code in google docs scripts.
But It is sending from my personal gmail address. I need define different mail address. Cause I will use this for my company and mail need show like that sometest#companytsite.com
How can i do that?
My Code:
function Initialize() {
var triggers = ScriptApp.getScriptTriggers();
for (var i in triggers) {
ScriptApp.deleteTrigger(triggers[i]);
}
ScriptApp.newTrigger("SendConfirmationMail")
.forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
.onFormSubmit()
.create();
}
function SendConfirmationMail(e) {
try {
var ss, cc, sendername, subject, columns;
var message, value, textbody, sender;
// This is your email address and you will be in the CC
cc = Session.getActiveUser().getEmail();
// This will show up as the sender's name
sendername = "Your Name Goes Here";
// Optional but change the following variable
// to have a custom subject for Google Docs emails
subject = "Google Form Successfully Submitted";
// This is the body of the auto-reply
message = "We have received your details.<br>Thanks!<br><br>";
ss = SpreadsheetApp.getActiveSheet();
columns = ss.getRange(1, 1, 1, ss.getLastColumn()).getValues()[0];
// This is the submitter's email address
sender = e.namedValues["Email Address"].toString();
// Only include form values that are not blank
for ( var keys in columns ) {
var key = columns[keys];
if ( e.namedValues[key] ) {
message += key + ' :: '+ e.namedValues[key] + "<br />";
}
}
textbody = message.replace("<br>", "\n");
GmailApp.sendEmail(sender, subject, textbody,
{cc: cc, name: sendername, htmlBody: message});
} catch (e) {
Logger.log(e.toString());
}
}

According to the documentation: https://developers.google.com/apps-script/reference/gmail/gmail-app#sendEmail(String,String,String,Object)
You should be able to pass in a from in the options.
GmailApp.sendEmail(sender, subject, textbody, {
from: "sometest#companytsite.com",
cc: cc,
name: sendername,
htmlBody: message
});
Nb. to avoid confusion sender should really be to
Now it also says that the email address you want to send it from must be an alias, to check you can print out getAliases() to see if it exists. If not you should be able to follow these instructions:
