Hello all, I'm sure this has been covered somewhere before, but my googlefu is not up to the challenge.

Basically, I'm trying to configure quota plugin to use a dictionary service (specifically proxy with mysql) so that I can store the quota usage in a database and use that information in a lookup for postfix to reject mail if over quota. I'm doing this because postfix+avamis+dovecot setup with amavis re-injecting into postfix results in mail being effectively accepted before dovecot lmtp knows if mailbox is full.

I'm currently using quota maildir:

quota = maildir:User quota

and this works;

doveadm -Df tab quota get -u 'user@domain'

Quota name Type Value Limit % User quota STORAGE 55388 204800 27 User quota MESSAGE 4883 - 0

When I use quota dict:

quota = dict:User quota:%u:proxy::quota

I get this:

"doveadm -f tab quota get -u user@domain"

Quota name Type Value Limit % User quota STORAGE 0 204800 0 User quota MESSAGE 0 - 0

So far so good.

But manually setting database entry to values retrieved above with maildir quota results in this:

Quota name Type Value Limit % User quota STORAGE 54 204800 0 User quota MESSAGE 4883 - 0

I'm guessing this is returning values in KB, so that makes sense, I guess.

Attempting to recalc quota on one account using command:

"doveadm -f tab quota recalc -u user@domain"

returns with nothing, and when I repeat 'quota get' command, it says:

doveadm(user@domain): Fatal: User doesn't exist

Err............what?!

Indeed, looking in the database shows the account in question was actually DELETED!

Obviously, I've got something messed here, but I don't know what.

I need some guidance here.

Dovecot version is 2.1.12

Here is my config:

From dovecot-dict-sql.conf.ext:

connect = host=localhost dbname=maildb user=dbuser password=dbpass

CREATE TABLE quota (

username varchar(100) not null,

bytes bigint not null default 0,

messages integer not null default 0,

primary key (username)

);

map { pattern = priv/quota/storage table = email username_field = address value_field = quota_bytes } map { pattern = priv/quota/messages table = email username_field = address value_field = quota_messages }

CREATE TABLE expires (

username varchar(100) not null,

mailbox varchar(255) not null,

expire_stamp integer not null,

primary key (username, mailbox)

);

map { pattern = shared/expire/$user/$mailbox table = email value_field = expire_stamp

fields { address = $user maildir = $mailbox } }

Other than some guesswork, I've not got the FOGGIEST idea what the settings in the file actually mean; it doesn't seem to be documented anywhere.

Also, the quota plugin settings, at least with respect to using a proxy service, don't seem to be real explanatory either, e.g. the reason I'm using %u for the user is because I stumbled across a post suggesting that leaving it blank would result in just getting the username instead of the username@domain. This is not at all obvious from the documentation, IMO. The docs would benefit greatly from some example use cases (no, I'm not volunteering; I'm TERRIBLE with documentation ;) ).

Anyway, if someone could proffer some help or at least guidance here, I'd be very grateful.
