problem Dovecot 2.2.13 does not send the information on ending the quota to user
Hi.
I have Dovecot + Postfix + MySQL.
Version of Postix: 2.11.3-1
Version of Dovecot: 2.2.13
Operations system is: Debian GNU/Linux 8.2 (jessie)
Postfix have patched (patch VDA - http://vda.sourceforge.net) for using with
quota, it means that file "maildirsize" in
mail directory already exists and changed when add/delete mail.
Quota for virtual box take in MySQL db.

Those plugin is successfully loaded and checked. When removing/receiving emails
percent of employment, respectively
changes.
I read in dovecot manual, that the notification send only when the quota border
crossing - then I tested like this:
Clears the box up to 60% and then send letters, which occupy about 5% more of
allocated quota. And so the lead up to
95%. But reports of ending the quota not be sent.
In what may be another problem?
Thanks.
