If you don't plan on using your mail server for an outbound relay, you
don't need SASL or SMTP Auth.  You only need these if you have users
that may be relaying mail from arbitrary IP addresses (road warriors).
 Even then I recommend VPN for this.

Maildir is the better format.  mbox can cause problems if you keep
messages on the server and let it get too large.  I don't think there
are any IMAP servers that support mbox for storage either.  Fetchmail
uses your MTA/MDA for delivery, so it is not aware of the mailbox
storage format, nor does it care.

Personally I like a combination of postfix and
courier-imap/courier-pop.  If you throw MySQL into the mix with
postfixadmin then you have a really quick virtual mail system that
does not require system users for mail.
