Yes - blocks get automatically run by Phoenix. Before we split James
into multiple blocks it was straightforward to specify what services
were run. I haven't had time to play with current set-up for that.
The IMAP code generally needs some attention, so I wouldn't rely on it
for examples.
And, yes, components within blocks should be set up by their block, I
think.
