I have Isp configured and running on a Centos 5 server. I just finished installing roundcube mail and would like to configure the server so that www.any_domain_forwarded_to_my_server.com/mail pulls up the roundcube login. I tried making a file in /etc/httpd/conf.d/ with Alias /mail /var/www/web18/web but it is not parsing the .php files and just brings up a blank page. What can I do to fix it?
