If you ever need to find out what mime types are installed on your linux server, you can simply look up the mime type file by going to;
/etc/mime.types.
If the list is not at that path, you can do a find or locate for the mime.types list.
Also, if you need to add a mime type to the server, you can add to that list or you can add them by going to the .htaccess file for the account/website you want to add it for and add it directly to the .htaccess file.
