I have a similar problem to: http://www.howtoforge.com/forums/showthread.php?t=51937&highlight=application/x-httpd-suphp I'd like to access squirrelmail via webmail.example.com, but can't even open it via example.com/squirrelmail. I succeed with 192.168.x.x/squirrelmail but example.com/squirrelmail will ask to download the application/x-httpd-suphp file.
