And this was probably because you saw the following

Warning: Private archive directory is other-executable (o+x).
         This could allow other users on your system to read private
         If you're on a shared multiuser system, you should consult the
         installation manual on how to fix this.""")

And you then did the equivalent of

  chmod o-x archives/private/

without actually reading and understanding the warning in the
installation manual at <http://www.list.org/mailman-install/node9.html>.

The -R in the above is unnecessary as all the subordinates should be
world readable and searchable already. You only need to ensure that the
web server can search the archives/private/ directory to find the
archives/private/LISTNAME directories pointed to by the
archives/public/LISTNAME symlinks.

Thus, archives/private/ must be either o+x or owned by the web server
user (Its group must be Mailman's group, 'list' in your case). The only
problem with its being o+x is if you have local, shell access users on
your server for whom you want to ensure no access to private list archives.
