Here's the thing... This is a side project. If it were my full time job, believe me, i'd be all about manual configuration and am not afraid of editing text files in the shell. We do it a lot actually. BUT, we don't have time to spend an hour configuring a new signup when we get 2 to 4 new sites every day or two.

We've been using the VirtualHosting capabilities on our Raq server (which is all administered via a fairly well laid out and executed web interface.) On the Raq, adding a new site takes about 30 seconds, and everything is configured for each site automagically. We have over 125 domains going on 4 IP's. Raq's are awesome for doing static hosting of small sites... but once we started adding CGI's and MySQL calls, the thing just couldn't take it. Which is why we got the new server.

We need something that allows us to add a site and have the tool do the rest (set up email, create directories, create users/aliases, ftp, etc etc...).

Any other ideas? =]
