@sean, I'm trying to follow your Dada Mail suggestion and hit my first snag: I don't see an option to create an Apache+PHP+CGI application. I created an Apache+PHP instead, but that doesn't give me access to Apache configs (that I can find).
Using your recommendation of adding a cgi-handler to an .htaccess file worked...sort of. I was able to run the uncompress script, but I fail running the installer Do I need to have a similar file for each and every directory that Dada Mail uses?
