Mark's example of wanting to receive notification about automatically
generated alarms makes me wonder if we shouldn't use Received as the
loop prevention mechanism after all.  it's definitely the safest method
of prevention.  the risk is that users will run into hop count limits,
but I think most messages should be well clear of that.

yes, but even if the Right Thing is to use redirect, it's quite likely
that a non-trivial amount of people will use notify instead.
