Dear Dovecot experts,
I am in the process of planning migration from dovecot 2.3 to 2.4.1+dfsg1-6 on Debian Trixie, but userdb extra fields for quota_storage_size are ignored. All settings proved to work in 2.3; following per-user quota manual as outlined in [1].
Issue Cannot override setting quota_storage_size using userdb_quota_storage_size, but userdb_quota_storage_extra and userdb_quota_storage_percentage apparently work.
Setup Configures multiple userdb using driver passwd combined for a) user information and b) user-specific extra fields; auth. via passdb using driver pam defined in auth-system.conf.ext included by 10-auth.conf Excerpt from doveconf -n: … passdb system_pam { driver = pam } userdb userdb_01_passwd { driver = passwd result_internalfail = return-fail result_success = continue-ok } userdb userdb_02_quota { passwd_file_path = /etc/dovecot/quota-user-settings driver = passwd-file result_internalfail = return-fail result_success = continue } …
Excerpt from passwd file /etc/dovecot/quota-user-settings holding userdb extra fields: web1p1:::::::userdb_quota_storage_size=1200M
Default quota config excerpt from doveconf -n: … quota user { storage_grace = 100M storage_size = 750M quota_warning warn-95 { quota_storage_percentage = 95 execute quota-warning { args = 95 %{user} } } quota_warning warn-85 { quota_storage_percentage = 85 execute quota-warning { args = 85 %{user} } } } …
Result Userdb setting appear to work correctly as it combines both userdb files, see following output:
doveadm user web1p1
field value uid 644 gid 105 home /home/pop/web1p1 mail_path /home/pop/web1p1/mail system_groups_user web1p1 quota_storage_size 1200M
However, querying the quota only shows the default value, but not the user-specific setting.
doveadm quota get -u web1p1
Quota name Type Value Limit % user STORAGE 798830 768000 104 user MESSAGE 5617 - 0
Expected behaviour Any user should report default user quota (here 750M), but user web1p1 having user-specific setting for userdb_quota_storage_size=1200M should report a higher quota limit overriding the default quota setting.
I tried to specify user-specific values for userdb_quota_storage_extra and userdb_quota_storage_percentage, which worked; probably, because there were no default value specified in the config, yet? Setting userdb_quota_storage_extra to 200M works:
web1p1:::::::userdb_quota_storage_extra=200M
…
doveadm user web1p1
field value uid 644 gid 105 home /home/pop/web1p1 mail_path /home/pop/web1p1/mail system_groups_user web1p1 quota_storage_extra 200M
…
doveadm quota get -u web1p1
Quota name Type Value Limit % user STORAGE 798830 972800 82 user MESSAGE 5617 - 0
Quota is reported as correctly as 750M+200M=950M.
Same approach works when setting userdb_quota_storage_percentage, e.g. to a value above 100.
