Hey Everyone,

I am pleased to announce Mailman Core 3.3.1 is now out.

This release includes support for bounce processing, which had been lacking in Mailman 3 until now. So, after upgrading to this release, you will notice bounce related notifications from Mailman 3 being sent out to list owners if the list has bounce processing enabled (which, most list do by default).

Postorius changes for new bounce processing options are coming out soon, I would like the current head to bake in a little longer since it went through bootstrap 4 upgrade recently. Expect it to be out in about a month. If your users would really care about bounce processing being enabled and not being able to tune threshold and notification parameters in the web interface, you might want to wait for Postorius's next release before upgrading.

It also exposes all the remaining attributes of MailingList via REST API, so Postorius can expose them in the Web Interface. This should finally make all attributes of a MailingList manageable via Web Interface, without having to access command line interface.

There has also been a whole lot of bug fixes. A full list of changes can be found at:

The release is available via PyPI:

To install this release via pip, you can run:

$ pip install --upgrade mailman
