I don't believe that event reporting is working properly in sending emails to a gmail account (periodic reboot and ping reboot). If I try to send test emails they fail, a red failed banner drops down and no email is received.
I do, however, receive emails with the subject line "status change" I've attached a screen shot of one of these emails to this question. The emails report "online to offline" and "offline to online". Effectively, a periodic reboot, as scheduled.
Are these status change emails a separate notification from the event reporting emails? If they are, they may indicate what settings errors I have made in event reporting email setup.
