Something is not right then. One should never edit Defaults.py.
mm_cfg.py includes the contents of Defaults.py via this line:

from Defaults import *

Then in mm_cfg.py one overrides any settings previously imported from

In addition, the HTTP Error 403 - Forbidden, is not generated by invalid
host names or URL's. This error says the URL was located but the client
does not have permission to access it, this is a http server
configuration issue, not a mailman configuration issue.

I suspect the problem is the http configuration for the directory that
was originally posted omitted the "Options ExecCGI" which is required to
tell the http server it is permissible to execute cgi scripts in this

Here is what I use, adjust the path to your installation:

ScriptAlias /mailman/ /usr/lib/mailman/cgi-bin/
<Directory /usr/lib/mailman/cgi-bin/>
    AllowOverride None
    Options ExecCGI
    Order allow,deny
    Allow from all
