"""Process disabled members, recommended once per day.
This script cruises through every mailing list looking for members whose
delivery is disabled. If they have been disabled due to bounces, they will
receive another notification, or they may be removed if they've received the
maximum number of notifications.
Use the --byadmin, --byuser, and --unknown flags to also send notifications to
members whose accounts have been disabled for those reasons. Use --all to
send the notification to all disabled members.
Usage: %(PROGRAM)s [options]
Options:
-h / --help
Print this message and exit.
-o / --byadmin
Also send notifications to any member disabled by the list
owner/administrator.
-m / --byuser
Also send notifications to any member disabled by themselves.
-u / --unknown
Also send notifications to any member disabled for unknown reasons
(usually a legacy disabled address).
-b / --notbybounce
Don't send notifications to members disabled because of bounces (the
default is to notify bounce disabled members).
-a / --all
Send notifications to all disabled members.
-f / --force
Send notifications to disabled members even if they're not due a new
notification yet.
-l listname
--listname=listname
Process only the given list, otherwise do all lists.
