The way maildir delivery works is:

create the file in tmp/
hardlink it to new/
unlink from tmp/

The last two steps could be done with a rename() which would fix the JFS
problem, but since there's a tiny (practically non-existent with
Dovecot) possibility of that overwriting a mail file in new/ dir,
link()+unlink() is done.
