Thank you, tbh, I didn't read list_lists manpage.

That makes sense. The Debian package takes care to create symlinks to
those binaries in /usr/sbin, but it's good to know where to find those
on non-Debian systems.

Since Mailman's "bin" directory has 755 permissions on Debian, every
user can attempt to run these commands. Most directories (except
private archives) in /var/lib/mailman have world read/execute
permissions, but it seems that the actual data is owned by group
"list" and only readable by group/owner. So running either
"list_lists" or "list_members <listname>" result in a EPERM traceback.
