Depends on the hardware and the users - if they are regularly pushing multi-megabyte attachments you may need faster hardware than expected. But for normal users a Pentium-2 200 would be fast enough (just don't ask how I would know that)

External USB drives can fail in amazing ways :-) But I like your "backup strategy" > If you're looking at buying hardware, I'd recommend something like a > Dell SC-series (1425 if you want rack-mounting, they're nice).

Meh, if you build them yourself you can always be a lot cheaper and you can customize for your needs - I'm building a fanless box for routing purposes right now, nothing you could reasonably buy at these big vendors. If you don't have the experience go find a small shop in your area, they can offer better service. Building it myself saves ~30% compared to our "normal" shop, Dell would be even more expensive. > In my experience, I'd stay away from qmail for e-mail purposes, but > hey, it's all about freedom. Right. So most people will suggest postfix, then the usual weirdos jump up and yell exim ... and then the boss reads the MS propaganda and really needs an exchange server ;-) -- Stand still, and let the rest of the universe move
