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!
