I vividly remember this incident and more like it. I was coached by my manager to never reply all to an email addressed to a larger distribution group because of this exact reason. Not only were you annoying people, but everyone's email ended up getting delayed for an hour or two.
Can someone explain to me why the backlog would happen? Why they didn't have systems to protect from such a basic DOS attack?
