This is what keeps me away from self-hosting it, though. As long as there's some possibility that my ability to deliver email could get nuked, all because someone else made a mistake, it's not worth it to me, especially since using / sending email is mandatory for doing most things. I guess I'm just not really willing to take that sort of risk
