We used these messages as a prompt to check if an email was entered incorrectly. Any thoughts on whether this is a change on the QB server, or if there's a way to set up an email confirmation notification?no longer receiving email undeliverable notices from mail delivery systemI used to receive emails from mailer-daemon@lvmailappout13.intuit.com notifying me if a QB email notification was undeliverable. I no longer receive these emails. Is there a way I can receive them again, or a way I can program QB to send a notification if an email isn't delivered? I searched the forums already, but couldn't find anything relevant for my situation.
