[Mailman-Users] after new installation 403 Forbiden Access

[Guillaume Chartrand]

I know it's been posted many time but all the answer wasn't apply to me. So I will ask it another time
I run Red Hat Enterprise Linux 4 AS
I installed Python 2.6.6
I installed Apache 2.2.16
I download and try to install mailman 2.1.14

All the installation steps working fine, but when I try to create the first list with the web interface I've got the 403 Forbidden page
Whenever I try to reach
http://mywebserver.com/mailman/create
                                                                         admin
                                                                        listinfo

I've always get the 403 error.
Here is the output of the command ls -la /usr/local/mailman/cgi-bin/
drwxrwsr-x   2 root mailman  4096 Sep 30 14:57 .
drwxrwsr-x  20 root mailman  4096 Sep 30 14:57 ..

-rwxr-sr-x   1 root mailman 15666 Sep 30 14:57 subscribe

Here's some of the httpd.conf line

Alias /pipermail/   /usr/local/mailman/archives/public/
ScriptAlias /mailman/ "/usr/local/mailman/cgi-bin/"

<Directory "/usr/local/mailman/archives/public/">
        AddDefaultCharset Off
        Options Indexes FollowSymlinks MultiViews
        AllowOverride None
        Order allow,deny
        Allow from all
</Directory>

The apache runs with the user nobody
And this is an other command to see if right seems ok

ls -la /usr/local/mailman/lists/
total 12
drwxrwsr-x   3 root mailman 4096 Oct  1 08:39 .
drwxrwsr-x  20 root mailman 4096 Sep 30 14:57 ..
drwxrwsr-x   2 root mailman 4096 Oct  1 09:00 mailman

I've modified the mm_cfg.py also and add these line
DEFAULT_EMAIL_HOST = 'listes2.collanaud.qc.ca'
DEFAULT_URL_HOST = 'listes2.collanaud.qc.ca'
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

So what i'm doing wrong.
Thanks for helping me resolve that
