I'm preparing to migrate from qmail to... what, postfix? Basically, I'll be running the server install CD, and choose LAMP, DNS, and email... and letting Ubuntu do most of the dirty work.

What's the best way to keep my settings and emails? I believe that qmail is now setup to save in mbox format. I don't know how the users are saved; I only know that it uses VqAdmin, and that the guy who managed the server(s) before me hated Linux, so he used rpms (he had an old copy of RedHat) for everything he could and edited/tweaked as little as he could get by with.

Any help is greatly appreciated.
