Not quite. The remaining issue is archives because public archives are
the only things that are not accessed through a wrapper. That's an
important access issue, i.e. forcing private archive access to be only
via the 'private' wrapper/script which forces authentication.

Because public archives are accessed directly by the web server via the
'pipermail' alias and the symlinks in archives/public, the
archives/private/<listname>/ directories and their subordinate archive
contents must be accessible by 'other', but the archives/private/
directory itself has permissions 02771 to prevent 'other' getting the
names of the lists by reading the directory.
