The rules must be consecutive,

if your global config has

quota_rule1
quota_rule2

then the userdb must return

quota_rule3. Or it will overwrite an existing rule.

Hi,
 
 OK, I wrote this :
 

userdb {
 driver = passwd
 args = /etc/dovecot/quota-overrides
 
 result_success=continue-ok
 
 # Override fields from passwd
 #override_fields = home=/home/virtual/%u
 }

 but sorry I don't understand the following line 

 username::::::::::quota_ruleX=... where X is the next rule number.

 What should I write ?...... for instance :  ? something like that ??

That `*` there is actually mailbox mask. You have to return an additional quota_ruleN from your userdb for that user.

You can do e.g.

userdb {
   ..
   result_success=continue-ok}
}

userdb {
   driver = passwd
   args = /etc/dovecot/quota-overrides
}

and put in there 

username::::::::::quota_ruleX=... where X is the next rule number.

the count of : might be wrong.

Hi Again,
 
 Juste another one...
 
 The quota I've decided is 30Gb for everybody
 I would like to add an exception for the user AZT000 so here is my test :
 
 I put 60 GB for AZT000, but apparently, this is not seen :-( No error message
 Is there a general syntax for a specific user ?
 
 NB: I tried :
 quota_rule = azt000:storage=+60GB orquota_rule1 = azt000:storage=+60GB same results
 
 

plugin {
 quota = maildir:User quota
 quota_rule = *:storage=30GB
 quota_rule2 = Trash:storage=+100MB
 quota_rule3 = Spam:storage=+20%%
 # quota_rule = *:storage=70GB
 # quota_rule = *:storage=70GB
 quota_rule = azt000:storage=+60GB

 Thanks again

 Just for info
 
 [root@mbox1 xenia]# doveadm quota get -A |grep "STORAGE"
 Nothing at all ?? weird
 [root@mbox1 xenia]#
 
 [root@mbox1 xenia]# doveadm quota get -u <user1>
 Quota name Type Value Limit %
 [root@mbox1 xenia]#
 => Absolutely nothing is displayed ????
 
 
 normally, the size of the user1 email folder is about 21 Gb
 So..just modified the line :quota_rule = *:storage=100G
 But nothing has changed...

You are missing quota driver settings, the recommended settings are

plugin {
 quota = count
 quota_vsizes = yes
}

Aki

 Hi Aki,
 Thanks for your reply..
 
 I just tryed to ad it.. but this can't connect anymore .
 Here is my exact declaration "90-quota.conf"
 
 ( based on : https://doc.dovecot.org/configuration_manual/quota/ )

plugin {
 quota = count
 quota_vsizes = yes
 #quota = maildir:User quota
 quota_rule = *:storage=100GB
 # quota_rule2 = Trash:storage=+100MB
 # quota_rule3 = Spam:storage=+20%%
 # 20% of 100GB = 20GB
 quota_status_success = DUNNO
 quota_status_nouser = DUNNO
 quota_status_overquota = "552 5.2.2 Mailbox is full"
 quota_warning = storage=95%% quota-warning 95 %u
 quota_warning2 = storage=80%% quota-warning 80 %u
 quota_warning3 = -storage=100%% quota-warning below %u
 
 # LDA/LMTP allows saving the last mail to bring user from under quota to
 # over quota, if the quota doesn't grow too high. Default is to allow as
 # long as quota will stay under 10% above the limit. Also allowed e.g. 10M.
 quota_grace = 10%%
 
 # Quota plugin can also limit the maximum accepted mail size.
 quota_max_mail_size = 100M
 }

 
 The error message I have now is :
 
 Oct 06 07:23:35 imap(azt000)<7381><3pAIWajNgdcgAUHQ/kJ8Aikr1PIAQmFL>: Error: Failed to initialize quota: Invalid quota root quota: Invalid rule Trash:Storage=+100M: Unknown rule limit name: Storage

 Then you can see that I've removed the 2 lines 
 # quota_rule2 = Trash:storage=+100MB
 # quota_rule3 = Spam:storage=+20%%
 
 but without any success
 
 Effectively.. what is the Word "Storage" for Dovecot ?? no idea ... I just wrote what I saw :-)
 
 For info : all the mailbox are placed on a NFS storage.. Don't know if this help to locate the problem..
 Thanks and regards,
 
 
 

Did you try changing Storage => storage in your rule? It seems to be coming either from userdb or your config.

Try `doveadm user azt000` to if your userdb is providing these rules.
