Hello,
I am trying to set up file-dictionary based quotas while supporting the SETQUOTA IMAP command.
I am using the following configuration :
plugin { quota = dict:User quota::file:%h/Maildir/dovecot-quota quota_set = dict:file:%h/Maildir/dovecot-quota }
which enables correct quota accounting + setting through SETQUOTA.
A user's dovecot-quota file ends with the following contents :
priv/quota/limit/storage 5242880 priv/quota/limit/messages 20 priv/quota/messages 1 priv/quota/storage 8506282
which shows a correct accounting (1 mail received, ~8MB used) and correct setting after having used the following IMAP command through a master user :
A2 SETQUOTA "User quota" (STORAGE 5242880 MESSAGE 20)
*But* the problem is that I am unable to fetch the limits and consume them from userdb (as a consequence, the limits are never applied).
On the consuming side, I am using a dictionary userdb to try to fetch the 'priv/quota/limit/storage' value from the file but it does not work because the key is never found.
Here is my configuration :
userdb { driver = dict args = /etc/dovecot/dovecot-dict-quota.conf.ext }
and my dovecot-dict-quota.conf.ext file :
uri = file:%h/Maildir/dovecot-quota iterate_disable = yes
key quota { key = priv/quota/limit/storage default_value = 100 }
userdb_fields { quota_rule = *:storage=%{dict:quota} }
If I try to fetch the quota for that user :
# doveadm quota get -u ganael.laplanche@centralesupelec.fr
Quota name Type Value Limit
%
User quota STORAGE 8307 100
8307
User quota MESSAGE 1 -
0
the default rule is returned (100). The logs show :
May 16 12:02:45 mailhost1-saclay dovecot: auth-worker(12899): Debug: dict(Ganael.Laplanche@centralesupelec.fr): Lookup: shared/priv/quota/limit/ storage not found, using default value 100
We can see that the default quota rule has been applied because the key is not found. The problem is that a "shared/" prefix is always prepended when looking for the key I configured (priv/quota/limit/storage).
If I test the dictionary manually, the key is found :
# doveadm dict get -u ganael.laplanche@centralesupelec.fr "file:/var/vmail/l/ laplanche_gan/Maildir/dovecot-quota" priv/quota/limit/storage 5242880
Does anyone know how to prevent Dovecot from adding that prefix and make it fetch the correct value from userdb ?
