Brian makes a number of good points. I just have a couple of remarks/questions.
- MM3 DMARC handling seems to have improved from reviews I have seen
but NO BOUNCE PROCESSING.
I don't know why Mailman 3's DMARC mitigation is considered improved over Mailman 2.1. It's the same. The Settings and Postorius UI for them are more logical than MM 2.1, but they ultimately boil down to the same things.
The latest Mailman core (not yet released but available at https://gitlab.com/mailman/mailman/-/tree/master fully implements bounce processing. Prior to this, bounce events were stored in the database but not processed. Now they are.
My goodness. How do list managers keep their mailing lists clean? I know how much a hit to an IP address reputation can be done when a server is sending messages out to invalid email addresses. However I don't think I can fix that right? It is a Mailman core issue? So let's say it does get added to MM Core. How long will it show up in Postorius? Especially since not every feature in MM Core is revealed in Postorius already.
As I said, it's in the latest version of core. The list specific settings: 'bounce_info_stale_after', 'bounce_notify_owner_on_disable', 'bounce_notify_owner_on_removal', 'bounce_score_threshold', 'bounce_you_are_disabled_warnings', 'bounce_you_are_disabled_warnings_interval' and 'process_bounces' are not currently exposed in Postorius, but if Mailman 2.1 lists are imported with import21, they will be set appropriately and they will be in Postorius eventually.
