Since Postfix won't run pipes as root, pipe aliases found in these
files will be run as group 'nobody'.

>/usr/local/mailman/data/aliases is owned by root.mailman
>/usr/local/mailman/data/aliases is owned by mailman.mailman

And pipe aliases found in these files will run as group mailman.

If you have

MTA = 'Postfix'

Mailman will automatically maintain the aliases in
/usr/local/mailman/data/aliases* as you create and delete lists. You
will not need, nor should you have any Mailman aliases in

If all your Mailman aliases are in /usr/local/mailman/data/aliases*
with the current ownership, you won't have any further mail group
mismatch problems.
