Mail messages sent from nodemailer are not displayed in the user's mailbox

Question

I send messages from my domain account, but they do not appear in the user window (from nodemailer parameters). But when sending messages from messages, gmail services are displayed in the sent user field. I am missing something in the lower code

var transport = nodemailer.createTransport({ host: "xxxx.domain.com", auth: { user: 'xyx', pass: '123' } }); transport.sendMail(options, function (err, info) { if (err) { console.log(err) } console.log(info); });
