bin/list_members --nomail=bybounce lists those members whose delivery is
currently disabled by bounce processing because their bounce score
reached threshold. These are members that haven't yet been removed, but
will be after they've received and not responded to
bounce_you_are_disabled_warnings warning notifications.
These will show in the get_bounce_info output with
current score >= bounce_score_threshold
last bounce date in the recent past
email notices left < bounce_you_are_disabled_warnings
last notice date in the recent past
confirmation cookie = a hex string
The other 18 are either stale or currently bouncing but not yet
disabled. They will all have
current score < bounce_score_threshold
email notices left = bounce_you_are_disabled_warnings
last notice date = (1970, 1, 1)
confirmation cookie = None
The difference between stale and current is whether last bounce date is
older than today - bounce_info_stale_after days.

Please send them to me or post them here so we can improve the heuristic
bounce recognition. You may sanitize them by munging email addresses to
a form like user at example.com, list-bounces at example.com, etc. and if the
original list post is included, you may replace it with a note, but
otherwise we would like the exact headers and MTA boilerplate from the

If you set bounce_notify_owner_on_disable to Yes, you will get a notice
including the actual bounce DSN when the member's delivery is first
disabled by bounce. Beginning in Mailman 2.1.19, you can set
bounce_notify_owner_on_bounce_increment to Yes to receive a similar
notice every time a member's bounce score is incremented, i.e., for at
most one bounce per member per day.
