Hi,
I'm trying to setup quota with the following layout
CREATE TABLE "domain" (
"id" INTEGER,
"name" TEXT,
"active" INTEGER DEFAULT 0,
PRIMARY KEY("id"),
UNIQUE("name")
)
CREATE TABLE "address" (
"id" INTEGER,
"localpart" TEXT NOT NULL,
"domain_id" INTEGER NOT NULL,
PRIMARY KEY("id"),
UNIQUE("localpart","domain_id")
)
CREATE TABLE "mailbox" (
"id" INTEGER,
"address_id" INTEGER,
"active" INTEGER DEFAULT 0,
"password" TEXT,
"quota_bytes" INTEGER DEFAULT 0,
PRIMARY KEY("id")
)
As I like to update the quota and I like to use a dict/map I'm not sure if I
can update this following:
map {
pattern = priv/quota/storage
table = maibox
value_field = dummy
fields {
value_field = quota_bytes
id = mailbox_id
}
mailbox_id will be queried using password_query using: "mailbox.id as
mailbox_id"
Using such map I hope to be able to use:
SELECT quota_bytes FROM mailbox WHERE id = '$mailbox_id'
INSERT INTO mailbox (quota_bytes) VALUES ('$value') ON DUPLICATE KEY UPDATE
quota_bytes='$value'
Can someone help me with this ?
Hi Matt
as far as I know the quota plugin with the dict backend requires you to
configure the name of your username field in the map. The usual way to
configure it is to have a quota table like in the documentation.
https://doc.dovecot.org/configuration_manual/quota/quota_dict/
In your case where you don't have a username field in the table that
stores the quotas, then depending on your database, you may be able to
create a view that does include the username and configure that in Dovecot.
The quota plugin updates the values of two fields holding the number of
messages and the number of bytes used. I noticed you don't have the
messages field. I suggest to add it.
You shouldn't need to write any queries to update the quota: Dovecot
will generate the queries.
On a final note, before you invest time in this, it may be worthwhile
keeping an eye on the future plans
https://doc.dovecot.org/3.0/installation_guide/upgrading/from-2.3-to-3.0/
You could use the count backend with quota plugin (which is the
recommended backend for new installations) and then use the quota_clone
plugin to keep your database in sync.
