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.py
that 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/bounce
and maybe other logs in that directory.
