Hi.

I installed the latest version of dovecot (v 2.2.21). But dovecot still doesn't send the information on ending the quota to user.

dovecot --version

2.2.21 (5345f22)

before reporting an issue, please try a version made this millenium, 2.2.9 is older than my gran or take it up with your distro, dovecot doesnt make the distro version they do

Hi.

I have Dovecot + Postfix + MySQL. Version of Postix: postfix_2.11.3-1ubuntu1_amd64 Version of Dovecot: 2.2.9 Operations system is: Ubuntu 15.04 x64

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.

Check that the socket has a quota-warning:

lsof |grep quota-warning

Verify that the plugin quota is running I doing like this:

doveadm -D -v quota get -u rrr@mydomain.ru

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.
