[Mailman-Users] Hevy resource footprint forces backdrop to mailman 2.1

Greetings,

after many years of smoothly running a mailman2 instance I had to migrate my virtual server to a new provider. There I found, that mailman2 was no longer supported and tried to migrate to mailman3

.. with much pain and no success. Mailman3 keeps crashing my v-server and swallows almost every mail sent to any of the migrated lists.

So I wanted to switch back to mailman 2.1.39 by installing from the source package and found that this also fails due to missing python2 support.

How to solve this?

Thank you very much
