I would advise against running your own web server unless you really know what you are doing. I'm sure you know how to setup a web server, but email deliverability (getting past spam filters of the big email providers) is a huge pain in the *. So much that I don't even attempt it these days, I just outsource my email.

Ok, let's change the context then. What if I run a web hosting company and want to offer an installable package that includes an MTA, MDA and a front end for viewing/sending mail? (I don't run a web hosting company, so I'm sure there are other things that need to go into that mix.) The customer would click a button and we would configure everything on their VPS or whatever. If that's not plausible enough, maybe I'm a web hosting company that just offers to host your email and now I've got enough scale to make it worth investing resources to ensure deliverability and spam filtering. At some point it's got to be worth running your own email infrastructure and for those scenarios, is there an installable front end that has the Gmail special sauce?
