Maildir allows you to move / delete messages between mailboxes without
re-writing the entire spool file.  This should have obvious advantages
in multi-user setups since users re-writing 100's of megabytes, (i've
even got people with well over 2GB mail folders) would obviously bring
the server IO to it's knees in no time.  It should also be much easier
to create incremental backups with maildir format.

But there is almost no advantage to single user, since the re-writing of
the mail file should happen neatly in the background.  And indeed, the
old mbox format is much faster for such activities as searching your
e-mail (if you are actually searching the contents of the message bodies.)
