  # Rather annoyingly, ActionMailer templates have no knowledge of the context
  # in which they are invokved, unlike normal view templates. This is strange
  # and, at least for Hub, unhelpful. We could insist that the system installer
  # configures some static value for the default host for links, but that's a
  # horrible kludge - once the application is running it always knows its host
  # via the "request" object.
  #
  # This filter patches around this Rails hiccup by wasting a few CPU cycles on
  # auto-setup of the e-mail host.
