It appears that Mailman is appending the bounce message to the probe
and in this case there were "a couple hundred" subscribers in the
washington.hostforweb.net domain that bounced.

In any case, this seems to be sufficient reason to not append the
original bounce mesage to the probe.

I'm far from fluent in Python, but it looks like either

  self.sendProbe(member, msg)
in the routine
  def registerBounce(self, member, msg, weight=1.0, day=None):
in Bouncer.py

  def sendProbe(self, member, msg):
in Deliverer.py

are places where this can be addressed.
