Why does postfix need to traverse the directory? My understanding of
the benefit of maildir is that the MTA doesn't need to avoid
overwriting a file, locking, etc. and any other issue that mbox has
to deal with.

An IMAP server, though, does have to look at the contents of the
directory. It can index the files, though, or use a better
filesystem (one that uses btree for allocation).

Still, why was this in a Postfix book?
