Apologies for the unscheduled 3 hour maintenance - in an effort to figure out where our missing emails were going we tried a server reboot, which resulted in unexpected downtime when the server didn't want to wake back up. We'll make sure to let everyone know ahead of time if we plan on doing something like that again.
In related news, the backlog of emails going back to the weekend has apparently been delivered, in case anyone's confused about suddenly receiving a pile of emails they were expecting earlier this week. Mails should be working as expected now, but as usual please do file a ticket if you're still having troubles receiving emails for account or password recovery!
