quota-status returns quota_status_success when email would put user over quota

Hi list,

I am attempting to get quota-status service working, so I can deny email 
at the initial smtp dialog instead of generating bounces with lda.

I can't seem to get quota-status to return quota_status_overquota, even 
when an email would put an account over quota.

Quota in general works fine:
Jan 22 06:39:23 mail dovecot: lda(xx at yy.dk): 
msgid=<25c5bdb20d58fc4f649f716a947613dc at zz.org>: save failed to INBOX: 
Quota exceeded (mailbox for user is full)
Jan 22 06:39:23 mail dovecot: lda(xx at yy.dk): 
msgid=<25c5bdb20d58fc4f649f716a947613dc at zz.org>: rejected: Quota 
exceeded (mailbox for user is full)

The system is a pretty standard debian 8 box running virtually on a 
kvm/ovirt cluster:
root at mail:~# dpkg --list | grep dovec
ii  dovecot-core                   1:2.2.13-12~deb8u1 amd64        
secure POP3/IMAP server - core files
ii  dovecot-imapd                  1:2.2.13-12~deb8u1 amd64        
secure POP3/IMAP server - IMAP daemon
ii  dovecot-lmtpd                  1:2.2.13-12~deb8u1 amd64        
secure POP3/IMAP server - LMTP server
ii  dovecot-mysql                  1:2.2.13-12~deb8u1 amd64        
secure POP3/IMAP server - MySQL support
ii  dovecot-pop3d                  1:2.2.13-12~deb8u1 amd64        
secure POP3/IMAP server - POP3 daemon

Mail storage is local XFS partitions as far as the dovecot server knows. 
Behind the scene its actually raw disk images on NFS shares from a SAN 
towards the kvm/ovirt cluster.

I test by using nc towards the quota-status instance:
root at mail:~# printf "recipient=kptest at
asom-net.dk\nsize=1000000000\n\n"
| nc -q1 localhost 12340
action=DUNNO

User has 500MB quota:
mysql> SELECT 
CONCAT('/data/vmail/',CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1)))
AS home, 110 AS uid, 110 AS gid,
CONCAT('*:storage=',mailquota,'M') AS
quota_rule FROM virtual_users WHERE email='kptest at asom-net.dk';
+--------------------------------+-----+-----+----------------+
| home                           | uid | gid | quota_rule     |
+--------------------------------+-----+-----+----------------+
| /data/vmail/asom-net.dk/kptest | 110 | 110 | *:storage=500M |
+--------------------------------+-----+-----+----------------+
1 row in set (0.00 sec)

maildirsize seems ok:
root at mail:~# cat /data/vmail/asom-net.dk/kptest/maildirsize
524288000S
685 1
690 1

Quota-status will return unknown user if that is the case:
root at mail:~# printf "recipient=kptest2 at
asom-net.dk\nsize=1000000000\n\n"
| nc -q1 localhost 12340
action=551 5.5.1 User not found

If I do a strace on the quota-status PID, it seems to do a stat on the

including the last few lines):

It seems like sort of permission issue?
root at mail:~# su - vmail
No directory, logging in with HOME=/
$ id -a

$ cat /data/vmail/asom-net.dk/kptest/maildirsize
524288000S
685 1
690 1

/data/vmail/asom-net.dk is actually a symlink, maybe that could be of 
importance?:
root at mail:~# ls -ld /data/vmail/asom-net.dk
lrwxrwxrwx 1 root root 19 Jan  9 11:18 /data/vmail/asom-net.dk ->

drwx------ 9 vmail vmail 4096 Jan 23 08:55 /data/mnt1/asom-net.dk/kptest/

-rw------- 1 vmail vmail 23 Jan 12 16:50 
/data/mnt1/asom-net.dk/kptest/maildirsize

Anyone have any idea what might be wrong here?

quota-status returns quota_status_success when email would put user over quota

Hi list,

We still did not manage to get quota-status working.
We're hoping someone can provide some feedback/ideas on how we may 
investigate this issue further?
Is it likely to be a bug fixed in a newer version?

Regards,

Kristian

Tried this and works here. Doveconf -n output with regards to quota settings is
very similar, i use a quota dict, not maildir, spotted one difference i
commented in your doveconf -n and i'm using version 2.2.27 from source

The one line i'm missing here from your doveconf -n output is mail_plugins =
" quota" set in conf.d/10-mail.conf

Have you added quota to the global mail plugins setting?
