How to change sender name different form authenticated email?

 var nodemailer = require('nodemailer');

// Not the movie transporter!
  var transporter = nodemailer.createTransport({
      service: 'gmail',
      auth: {
          user: '*****@gmail.com', // Your email id
          pass: '*******' // Your password
      }
  });




var mailOptions = {
           from: varfrom_name, // sender address
           to: varto, // list of receivers
           subject: varsubject, // Subject line
           text: vartext, // plaintext body
           html: varhtml // html body
       };


       console.log(mailOptions);

       // send mail with defined transport object
        transporter.sendMail(mailOptions, function (error, info) {
           if (error) {
               return console.log(error);
           }else{
             return console.log(info);
           }
       });

I want different sender address from the authenticated one ? Suppose I authenticated data with abc@gmail.com, but I want to send the mail from xyz@gmail.com to def@gmail.com. How to do that in node-mailer ?

// Using send mail npm module

var sendmail = require('sendmail')({silent: true})
      sendmail({
        from: ' xyz@gmail.com',
        to: 'def@gmail.comh',
        subject: 'MailComposer sendmail',
        html: 'Mail of test sendmail ',
        attachments: [
        ]
      }, function (err, reply) {
        console.log(err && err.stack)
        console.dir(reply)
      })

But the mails coming in the span box and the mails that we are sending is won't showing in the sent mail of sender mail address ?

I hope i will able to elaborate my question
