I have my domain's email set up with Google Apps, and I am interested in sending automated emails (when users register, for example) with the From and/or Reply-To field being "[email protected]". I have a few questions pertaining to how this is done:
Should I actually set up a user in Google Apps named "no-reply"?
If not setting up a "no-reply" user, should I log in with a real address (e.g.: "[email protected]") and send the email as being from "[email protected]" instead? Or should I simply use the Reply-To email header?
If it's necessary to use the Reply-To header, is there a way to block the true From address (i.e.: the username I used to log into Google's SMTP server)?
