If your ISP is running Mailman's cron jobs on a regular schedule - in
particular if cron/disabled is run daily - the unsubscribe for a user
will come exactly (bounce_you_are_disabled_warnings times
bounce_you_are_disabled_warnings_interval) days after the notification
to the admin that the user's delivery was disabled by bounce
processing.
If the unsubscribes come after long, seemingly random delays,
cron/disabled is not being run daily by cron. Once a user's delivery
is disabled by bounce, the subsequent user notifications and eventual
unsubscribe are controlled entirely by the
bounce_you_are_disabled_warnings and
bounce_you_are_disabled_warnings_interval list settings and the
running of cron/disabled which is what sends the warnings and does the
eventual unsubscribe.
