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(box1@domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning: quota-warning box1@domain.com (because bytes=3713971 -> 7301217 over limit 4096000) Jun 10 11:08:20 srv1 dovecot[39677]: imap(box1@domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning: quota-warning box1@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
