Mailman package and ubuntu pro

[ciberfox]

Hi everyone,
I wanted to know if the Ubuntu Pro service also includes support for updating the Mailman package and, in particular, security fixes.
Unfortunately, this tool is no longer or almost maintained by the developer, and I have not found a valid alternative that guarantees solid management of mailing lists with public access.

We are not Canonical employees and have no special insight into Pro.

The "Mailman" package was removed from Ubuntu after 20.04.
In Ubuntu 18.04 and 20.04, the package was in the Universe pocket of the Ubuntu repos.

Pro promises security updates to some (not all) Universe packages.
So maybe they will, maybe they won't.

The free tier of Pro does not include any further maintenance or support. (No bugfixes or version bumps)
There is no promise to free-tier customers that Canonical engineers will adopt the source code.

For an authoritative answer from the Pro product team...
Paid tier customers should consult their service contact.
Free tier customers can ask at https://discourse.ubuntu.com/t/ubuntu-pro-faq/34042
