Hi everyone,

I recently redeployed our mailman3 server. As the owner for one of our mailing lists, I received a huge amount of subscription disabled notification emails. These emails mentioned that the subscription was disabled due to bounce score. Furthermore, we received a few emails from our subscribers saying that they have functioning email addresses and not sure why there were bounces and that their subsctiptions had been disabed.

See https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...

I have some questions:

1. Why do mailman mass send out subscription disabled notification emails to admins after it's been redeployed?
2. I have "Bounce disable warnings" set to 3 and "Bounce disabled warnings interval" set to 7d. How come there are still so many emails seem to be disabled but not unsubscribed? Hence we receiving so many subscription disabled notification emails.
3. What could have cuased functioning emails to bounce and therefore being disabled?

The answer to all those is you upgraded from a Mailman core version prior to 3.3.1. Prior to that, bounces were recorded in the database but not processed. when you upgraded, they all got processed at once.

See https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/... which includes a mailman shell interaction to re-enable all the subscriptions disabled by bounce.
