"""Throw email at Mailman as fast as you can.

This is not a unit test, it's a functional test, so you can't run it within
the unit test framework (hence its filename doesn't start with `test_').
Here's how I use this one:

- set up a dummy list

- add an alias to your MTA, say `devnull' that pipes its messages to, you
  guessed it, /dev/null

- make this address a member of your list

- add another address to `accept_these_non_members', let's call it ok@dom.ain

- change the FROMADDR variable to ok@dom.ain

- change the LISTADDR variable to point to your list

- run this program like so: python fblast.py N
  where N is the number of seconds to sleep before sending the next msg

- let this run until you're tired of it, then hit ^C
