I would change it to:

* Auto-Delete= Yes,Full-Auto,Delay(5),Max(100)

With this setting you will not get any bounced messages. LISTSERV
keeps track of  "fatal" errors per subscriber it can interpret. Non-fatal
errors like "mail box full" will be discarded. If it detects any fatal errors
(per subscriber) they will show on a daily error report sent to you.
If a subscriber has a fatal error 5 days in a row, they will be auto-deleted
and you will be notified. If they have over 100 fatal errors any time within
the 5 days they will be deleted also, it's whichever comes first. So
depending on the volume of your list, you may want to adjust the 100.
