Mailman mailing appears in public list when set to private

Perhaps a noobie question, as we just started looking at Mailman. We have a rather large Majordomo install with over 100 lists spanning 15 years and we are considering moving to Mailman. We thought it would be wise to learn all the ins and outs of Mailman in Cpanel before getting to far ahead of ourselves. What we've done: In cpanel we enabled Mailman, and created our first list which we set to private. However, when we send an email to listname-request@domain.com[/EMAIL] with 'lists' in the subject, the email we get back shows: - Results: Public mailing lists at domain.com: 1. List name: mylist Description: n/a Requests to: [EMAIL='testjames-request@opengamingalliance.org">mylist-request@d[/EMAIL]omain.com - Done. --------------- On the cpanel server we see this directory structure: [/usr/local/cpanel/3rdparty/mailman/archives]# ls -la private/ total 24 drwx--x--- 6 mailman nobody 4096 Nov 15 12:13 ./ drwxrwsr-x 4 mailman mailman 4096 Nov 29 2013 ../ drwxr-x--- 2 mailman nobody 4096 Nov 29 2013 mailman/ drwxrwx--- 2 mailman mailman 4096 Nov 29 2013 mailman.mbox/ drwxr-x--- 2 mailman nobody 4096 Nov 15 12:13 mylist_domain.com/ drwxrwx--- 2 mailman mailman 4096 Nov 15 12:13 mylist_domain.com.mbox/ [/usr/local/cpanel/3rdparty/mailman/archives]# ls -la public/ total 8 drwx--x--- 2 mailman nobody 4096 Nov 15 12:13 ./ drwxrwsr-x 4 mailman mailman 4096 Nov 29 2013 ../ -rw-r--r-- 1 mailman mailman 0 Sep 18 23:06 index.html In both the mailman settings and cpanel settings, we see the list is marked Private. Did we miss a setting, or is there something else we need to do, to ensure our list is not accidentally visible to the public. Thanks.
