Hi,
I am still struggling with this, and would appreciate any help ayone can
give. Let me try to explain step for step.
I created a test account t...@company.com:
root@dovecot:/# doveadm quota get -u test
Quota name Type Value Limit
%
STORAGE 1209 1368
88
MESSAGE 35 -
0
As you can see, the test mailbox is 88% full, so it should receive
warnings, because in dovecot.conf I have set:
plugin {
quota = maildir
quota_rule = ?:storage=5G
quota_rule2 = Trash:storage=+100M
quota_warning = storage=97%% quota-warning 97 %u
quota_warning2 = storage=95%% quota-warning 95 %u
quota_warning3 = storage=90%% quota-warning 90 %u
quota_warning4 = storage=85%% quota-warning 85 %u
quota_warning5 = storage=80%% quota-warning 80 %u
quota_warning6 = -storage=100%% quota-warning below %u
}
We use a script to send out the email warnings, configured like this:
service quota-warning {
executable = script /usr/local/bin/quota-warning.sh
unix_listener quota-warning {
user = vmail
mode = 0666
}
user = vmail
}
When running this script manually as vmail, the warning is delivered to
the test user:
sudo -H -u vmail bash -c '/usr/local/bin/quota-warning.sh 90 test'
However, in practice: dovecot never sends out any quota-warnings. It
just starts generating delivery failures when the mailbox is over 100%.
We define the per-user quota in the first line of each user's
maildirsize file, for the test user: /var/vmail/test/Maildir/maildirsize
Here is a debug=yes log file of 88% full incoming mailbox delivery:
