Niels,
This is correct, but from a pure technical viewpoint this will be easier to
solve with the new version of mailman 3 (which is a groundbreaking rewrite of
mailman) and much more transparent to extend or modify in functionality if
"required".
But the new mailman version is still - compared to the technical step behind
- very "new" / young - so it may take still some time to find most mailman
installations out there migrated to the new mailman.
Thanks for the update! Perhaps we can consider this at some point.
Jari
