quota for subfolder with prefix=INBOX.

[Jogi Hofmüller]

Hi all,

We use prefix=INBOX. in order to keep things as they were on the old
server. Now I started playing with quota and have trouble getting the
additional quota for Trash and/or Junk working. My expectation was that
once a user is over quota and moves email to trash sh/e should be able
to receive new email again. That's what I cannot get to work with our
setup.

Attached you find the config that I thought should be working. The
numbers are ridiculously low but that's just for testing.

Here is some output from doveadm

doveadm quota get -u user
Quota name Type Value Limit %
User quota STORAGE 5422 5120 105
User quota MESSAGE 18 - 0

doveadm mailbox status -u user "messages vsize" "*"
INBOX messages=13 vsize=3147033

doveadm mailbox status -u user "messages vsize" "INBOX.*"
INBOX.Drafts messages=0 vsize=0
INBOX.Sent messages=0 vsize=0
INBOX.Trash messages=5 vsize=2475790
INBOX.Junk messages=0 vsize=0

Hi all,

Since I did not manage to get quota for individual subfolders working I
tried toying with quota_grace, which also does not work for me :( My
approach was this:

plugin {
quota = maildir:User quota
quota_grace = 20%%
quota_rule = *:storage=5M

}

I expected normal delivery of email when user is at 103% quota but the
new email (even tiny ones with less than 1K) get's rejected with reason
'over quota'. Is this what dovecot is supposed to do or did I do
something wrong?

Regards,

I think your question is answered by first sentence in

Hi,

I think your question is answered by first sentence in
http://wiki2.dovecot.org/Quota/Configuration#Quota_grace

I guess I totally misunderstood the quota_grace option then. To be
clear: if the last mail brings the user just 1% over quota it doesn't
matter that I e.g. set quota_grace = 10 %% because every further email
will just be denied.

Too bad the extended quota for subfolders don't work in our setup (see
my initial email).

Cheers,

Yes. The grace value only protects the system from receiving huge last
message.

Alright then, back to the $subject. Who has a clue on how to get
extended quota for subfolders working when using prefix=INBOX.?
