Hi,
In our setup, we use two quota roots. One for user quota and one for domain quota. If a user has no quota, then the domain quota is applied.
For a user with user quota this is how it looks: # doveadm quota get -u test@shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 0 102400 0 User quota MESSAGE 0 - 0
In this case, the whole domain contains 21257 messages but the account itself contains 0.
For a user with only domain quota, this is how it looks: # doveadm quota get -u rick@shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 693299 - 0 User quota MESSAGE 12876 - 0
So far so good. My account contains 12876 messages.
Now I've sent a message containing a 1mb.bin as attachment to test@shellz.nl:
# doveadm quota get -u test@shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1440540 2560000 56 Domain quota MESSAGE 21258 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0
Seems to be fine, the message on disk is indeed 1.4MB and this has been added to both domain and user quota.
Now see what happens when I run the following command: # doveadm quota recalc -u test@shellz.nl # doveadm quota get -u test@shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1384 2560000 0 Domain quota MESSAGE 1 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0
The recalc action has updated the domain usage to reflect the specific user's usage (my 12876 messages are no longer counted).
We log domain usage (usage_domain) in a seperate table from mailbox usage (usage_mailbox). These are the queries that set the usage:
256 Query BEGIN
256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl'
256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl'
256 Query INSERT INTO usage_domain (bytes,domain) VALUES ('1418118','shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118'
256 Query INSERT INTO usage_domain (messages,domain) VALUES ('1','shellz.nl') ON DUPLICATE KEY UPDATE messages='1'
256 Query COMMIT
257 Query BEGIN
257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test@shellz.nl'
257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test@shellz.nl'
257 Query INSERT INTO usage_mailbox (bytes,userdomain) VALUES ('1418118','test@shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118'
257 Query INSERT INTO usage_mailbox (messages,userdomain) VALUES ('1','test@shellz.nl') ON DUPLICATE KEY UPDATE messages='1'
257 Query COMMIT
How do I prevent this from happening? It should only update the usage_mailbox table when I run the recalc command. Could this be because we use seperate tables for domain and user usage?

Thanks in advance to anyone who might be able to shed some light in this situation :).
