I've been trying to setup mailman on my Fedora box with Apache and Postfix. Here is one error that shows up when I restart my Apache server that I don't know how to fix: [warn] NameVirtualHost 70.88.225.1:80 has no VirtualHosts I think this is what is causing my mailman setup to not work.
It's a warning, you can ignore it. It means you have a NameVirtualHost directive somewhere in your Apache configuration, but no virtual host for that IP address. Have a look here: http://httpd.apache.org/docs/2.0/mod/core.html#namevirtualhost
