Apache/Mailman/Postfix VirtualHosts Problem

[kisong]

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
