by XFS do you mean filesystem quotas, yes ?

I was fighting domain quota for a long time, too. And I was never really successful at it, because group/domain quotas have multiple problems, and domain quota recalc is just one of them :)

After a long trial and error I ended up implementing XFS project quotas.

Hi all,

I’m a little bit confused about the quota plugin in dovecot and fighting the the issues the people had years ago. I spent readingg the old archives and the mailing list for 3 days and not able to get work some features. Single user quota is fine and simple, the group quota /for example domain based/ makes me unhappy.

Setup: CentOS7, dovecot comunity repo, dovecot 2.3.5

1. domain quota recalc domain quota recalc do not work properly. The domain qouta usage is worknig well, hwhen receiving/deleting mail, generaly if the operations are incremental. But if I run domain quota recalc, the doveadm is setting the domain quota after each user calculation, that means the domain quota is set to the last user.

2. multiple quota roots and rules According the documentation, there could be possible, from the sample configuration file

Multiple quota roots are also possible, for example this gives each user

# their own 100MB quota and one shared 1GB quota within the domain

plugin { quota = dict:User quota::proxy::quota quota2 = dict:Group quota:%d:proxy::quota_domain quota_rule = *:storage=1024M quota2_rule = *:storage=2048M }

But If I run [TEST] root@mail-store01.test.host.sk: /etc/dovecot # doveadm quota get -u '*' Username Quota name Type Value Limit % test01@test.host.sk User quota STORAGE 1 1024 0 test01@test.host.sk User quota MESSAGE 1 - 0 test01@test.host.sk Group quota STORAGE 7 - 0 test01@test.host.sk Group quota MESSAGE 3 - 0 test03@test.host.sk User quota STORAGE 7 1024 0 test03@test.host.sk User quota MESSAGE 3 - 0 test03@test.host.sk Group quota STORAGE 7 - 0 test03@test.host.sk Group quota MESSAGE 3 - 0

The idea is to have overall domain quota, but for user able to set it’s personal quota.
