Is it possible to send an email via Google Apps Script's MailApp class that would send the email from an existing (non Gmail) mailbox?
Currently, when I trigger an email from the code below, the email actually comes from a random Google server that is spoofing as the user triggering the email. I would like the email to be sent directly by a mailbox within my organization, if at all possible.
MailApp.sendEmail({
to: 'example@yahoo.com',
name: 'Jane Doe',
replyTo: 'example@google.com',
subject: 'Test',
body: 'Testing'
});
