In my case the only email that goes out is to: noreply@noreply.com, from: the admin email address. I have experimented with listing more than one email recipient and with user roles. Same result. None of the listed email accounts receive the email, I just get the mail delivery failed on noreply@noreply.com. This happens with 3.9 and 4.0. I am a site builder with no coding experience and have downgraded to 3.8 for now.
