I think it is, but it points at a need to update the testable
documentation.  There are some grammar issues ("who's" instead of
"whose") in the email implementation documentation, and some
inconsistencies as to the blessed method of sending email
(MailController vs sendmail).

I worry a bit about the "scalability" entry-- there are lots of places
where scaling issues can emerge.  For a given component, it's not
necessarily clear how it needs to scale until it's been used on
production.  Premature optimization is a danger here, but there's always
a judgment call about whether an optimization is premature.
