Postfix doesn't need absurd hardware.
A decent dualcore machine can handle just about anything you can throw
at it - that is, in your situation.
I deduce that your situation is < 1 million message per hour, since you
clearly haven't done this before.

So that's 1GB per user ?
Get 4 or more disk drives and put them in RAID-10 on a hardware controller.
You'll also have to learn a lot about IMAP, maildirs, and message access

You say nothing about expected mail loads, peak speed, or spam inspection.
Or network capabilities.
Or availability requirements.
If you are serious about running a mail server for end-users, get at
Multiple MXen are a standard feature of SMTP, and a backend mailstore
can be split up by users.
That way, if one goes down, the other will store its half of messages
and queue the rest until you have the second one back up.
