Dovecot doesn't try to enforce filesystem quota limits. It just handles
the EDQUOT error from write(). Preferrably this shouldn't happen to
index files and if you're using maildir it can prevent user from doing
anything if it can't write dovecot-uidlist file.

So the only thing that the fs quota plugin does is report the limits and
current usage to clients via IMAP QUOTA commands.
