OK, let me try again.
>From the Mailman-2.1.5/NEWS file:
- The bounce processor has been redesigned so that now when an
address's bounce score reaches the threshold, that address will
be sent a probe message. Only if the probe bounces will the
address be disabled. The score is reset to zero when the probe
is sent. Also, bounce events are now kept in an event file
instead of in memory. This should help contain the bloat of the
BounceRunner.
What appears to have happened in your case is that you have "a couple
hundred" subscribers in the washington.hostforweb.net domain that all
bounced to the point of reaching the threshold causing a probe message
to be sent to each of the bouncing addresses. In at least one case and
maybe in all, the bouncing address was actually valid because the
probe reached the subscriber.
The problem here is that the bounce message that caused the score to
reach the threshold was appended to the probe, and it contained a list
of all the bouncing addresses in the domain.
I don't think it is necessary for Mailman to append the bounce message
to the probe message, and I think your experience is good reason not
to. Unfortunately, there appears to be no way in 2.1.5 to fix this
short of hacking the python code and I suggested a couple of places
where one could start looking if one wanted to do this.
As far as how often this might happen on your list is concerned, if all
or almost all the addresses are actually valid and do not normally
bounce, there was apparently some MTA transient situation that caused
these addresses to all be bouncing at once. If this is a situation
that might occur again, you might consider tuning your bounce
processing parameters to minimize the likelihood of valid addresses
reaching threshold. If, OTOH, almost all the addresses were in fact
bad, they are now gone and won't be "revealed" again.
