As long as you can send email to foo-list at example.com, I think that's all that
matters for right now.

My idea is that we'd bring up a test domain with a couple of test lists, and
let people subscribe and unsubscribe via email (e.g. foo-join at example.com and
foo-leave at example.com).  Then people could post test messages to the list and
we'd all see how MM3 performed under real-world conditions.

A few other things:

* My main goal right now is to get the core to releasable state by 11.11.11.
  This probably means it's got to go to beta fairly soon, probably no later
  than the end of the northern hemisphere summer (probably best right after
  GSoC ends).

* We don't need to wait until the web ui is ready, so we'll start with just
  the email interface.

* Probably best to run the system off of bzr trunk.  That way, you can much
  more quickly deploy bug fixes during this test phase.

* I actually don't need shell access if you're willing and able to maintain
  the system, provide logs if necessary, update the bzr branch, etc.

* I think the risk is small, but you should be prepared to deal with any
  runaway mail storms.  Since most of the queuing architecture is a fairly
  straight port from MM2, and we have at least a *decade* of experience with
  that subsystem, we should be in good shape.  But the MM3 code has been
  refactored and updated to more modern Pythonic idioms, so it's entirely
  possible that some catastrophic bug was introduced.  Don't be afraid, but be
  prepared. :)
