Yes, and what that means is that created subordinate directories will be
group 'list' and SETGID, and created subordinated files will be group 'list'

But, the owner, not the group, will be the id of the user that created
them which for archived files will normally be 'list' not 'www-data'
because the files are created by ArchRunner, not by the web server.

So, back to my original questions. What is the ownership of files
archived after you ran your 'chown -R', and can you access them, and
what were the ownership and permissions of some example archived
messages and their containing directories before you changed them?
