How to access squirrelmail through IP, not http://ip/squirrelmail but http://ip

Hi i want to allow users to access squirrelmail when they type http://192.168.0.51 and not http://192.168.0.51/squirrelmail

How do i go about to do that. Must i change something in the http.conf
And how can i only bind port 25 and port 110 to 192.168.0.51

 

You can either change the document root of that vhost, or you use the Alias directive: http://httpd.apache.org/docs/2.2/mod/mod_alias.html#alias
