Hello, I would like to kindly ask, if there is some recommendation for dovecot
quota configuration, to prevent quota-warning triggering when IMAP MOVE command
is executed close to some thresholds.
Problem seems to be this:
Jun 10 11:08:20 srv1 dovecot[39677]:
imap(b...@domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning:
quota-warning b...@domain.com (because bytes=3713971 -> 7301217 over limit 4096000)
Jun 10 11:08:20 srv1 dovecot[39677]:
imap(b...@domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning:
quota-warning b...@domain.com (because bytes=7301217 -> 3713971 below limit 4096000)
So during any IMAP MOVE, which is copy-then-delete process, quota goes over and
then below limit, triggering closest threshold.
Quota config:
quota = count:User quota
quota_vsizes = yes
# default, we specific user limits via sql
quota_rule = *:storage=0
quota_grace = 50M
quota_warning = storage=100%% quota-warning %u
quota_warning2 = -storage=100%% quota-warning %u
quota_warning3 = storage=90%% quota-warning %u
quota_warning4 = storage=80%% quota-warning %u
There is no way to prevent quota warnings in that situation!
Recommended fix does not seems to work (tried multiple namespaces):
quota_rule = Folder:storage=+100M
This will only prevent, that your users are unable to delete emails (==
copy to trash then delete) while at 100%.
It will not prevent the warning.
Kind regards,
Christian Mack
