It depends on the backend you use. If you use filesystem quota's, then
there is no need to use the dovecot LDA, because the actual quota usage
is already being updated by the filesystem/kernel itself.

However if you use Maildir++ quota, then something has to update the
maildirsize file so that it contains the actual usage of that Maildir.
So you need the dovecot LDA here, or another LDA that can update those
files in a compatible way.

However I prefer to always use dovecot's deliver, because it
automatically updates indexes and caches when a mail arrives, and this
cannot be done by another LDA because the indexes and caches are dovecot
specific.
