Due to some long time configuration issues, which have now been resolved, I think was missing some list events. Now I have to play catchup. I am not sure how bounce processing works. Lets assume that a list member's email address goes bad. Exactly what happens to the bounced message and how does the list owner get notified? Assuming the owner missed those notifications, how can (s)he tell which users have invalid addresses? Thanks.
The bounce score begins at 0.0. Each bounce (only one per day is counted) increases the score by 1.0 or 0.5 depending upon if the -bounces processing detects a soft error or hard error. Once the bounce score reaches 5.0, the subscription is set to NOMAIL, and for three successive weeks, once per week, a test mail is sent to the address asking the subscriber to re-confirm. If there is no response to these three mailings, then the address is unsubscribed. All of these parameters are configurable. The bounced mail that triggers the 5.0 score is sent to the list owners, the previous bounce messages are discarded. The unsubscribe notice is sent to the list owners.
I run a report daily
http://veenet.value.net/~msapiro/scripts/get_bounce_info.pythat tells me for each Mailman list, each subscriber that has a bounce score greater than zero. I review the report daily to spot bad addresses.
Look at the Mailman logs
/var/log/mailman/bounceand maybe other logs in that directory.
