While I agree that MX backups are a pita, it's important to note that something very common these days are routing issues. I have a SMTP server in NYC area that (new to me) can't deliver email to people who use Level3/CenturyLink due to some things outside of my control. I'm 100% sure the reverse situation exists somewhere even though I may not know about it today. So my resolution to others' corporate greed and neck beard routing laziness is more than 1 MX. -Jim P.
