Just found a flaw in my line of thought. This doesn’t work as expected as virtual(8) resolves the list recursively and nested mail lists will end up being send with the envelope sender of the umbrella list. Well, I might as well let the python program deliver straight to list members, that will save me the administrative burden of the second postfix instance. — Eino Tuominen
