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 test@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:
