Don't count namespace space in quota
Hello everyone!
I'm trying to figure a solution for this scenario.
I have the Dovecot IMAP using MDBOX (SIS) storage for the daily usage email.
For long term storage I'm preparing a namespace with MBOX storage.
I'm not using the altstorage logic because as far as I know it needs to have the same format as the base one and for archival I prefer to have the attachments inside the messages in an old/well known format supported by near any email software.
The problem at the moment is with quotas.
If the user has 5GB in his mailboxes and the long term "historico" namespace has another 5GB, the storage used becomes 10GB and I want the users to only see their "active" usage (5GB).
I have that space to be ignored (as defined in the wiki and dovecot documentation - my quota_rule5 ) but it doesn't seem to influence the usage reported by IMAP.
What am I doing wrong?
If I put the "historico"namespace with disabled = yes and do a "doveadm quota recalc" the values become correct but I need the namespace available so the users can recover their old messages if needed.
The relevant settings (AFAIK) I'm using are:
plugin {
quota = dict:FileQuota:ns=:file:%h/dovecot-quota
quota2 = dirsize:HistQuota:ns=@HISTORICO/
quota_clone_dict = proxy::quota
quota_grace = 10%%
quota_rule = *:storage=24G
quota_rule2 = Trash:storage=+128M
quota_rule3 = Junk:storage=+64M
quota_rule4 = INBOX:storage=+128M
quota_rule5 = ns=@HISTORICO:ignore
}
namespace historico {
disabled = no
hidden = no
ignore_on_failure = yes
inbox = no
list = no
location =
mbox:/mnt/mail-hist/historic/%d/%-2.2n/%n:SUBSCRIPTIONS=.imap/dovecot-subscriptions:LAYOUT=maildir++
order = 0
prefix = @HISTORICO/
separator = /
subscriptions = yes
type = private
}
namespace inbox {
disabled = no
hidden = no
ignore_on_failure = no
inbox = yes
list = yes
location =
order = 0
prefix =
separator = /
subscriptions = yes
type = private
}
userdb {
args = /etc/dovecot/dovecot-sql.conf.ext
auth_verbose = default
default_fields = home=/data/domains/%d/%-2.2n/%n lport=%{lport}
driver = sql
}best regards to all the Dovecot community, stay safe!

I think this should be:
quota2_rule = ns=@HISTORICO:ignore
Aki
Thanks for the suggestion.
That wasn't enough, finally found it!
The quota dict wasn't properly configured and were including all namespaces in the counting.
Instead of:
quota = dict:FileQuota:ns=:file:%h/dovecot-quota
I now have:
quota = dict:FileQuota::ns=:file:%h/dovecot-quota
The namespace selector were in the wrong parameter due to a missing : delimiter
Thanks!
