this is going to change tomorrow morning (https://github.com/edx/edx-platform/pull/1260) 

I'm a bit worried about the brittleness of these two lines generally, because you're hardcoding in something that's pulled partially from settings (we've got in our backlog a story about allowing courses to change what goes in the `[ ]` part of the subject and what goes as the "from" person on their emails - ie basically these things may very well change). Would be interested in @wedaly 's take on this.
