[Dovecot] Cant't get quota / dict work

[Nicola Tiling]

Hi

I have a mixed configuration for MAILDIR und MBOX accounts  LDA is  
exim. For maildir exim writes a maildirsize file and I can see the  
IMAP contingent in my mailclient.

But I can't find a solution for mbox. I tried dict with mysql, db, and  
pgsql - but notihing works for me.

- db: a file is written but it seems to be empty:
  1013 [mail] =db_dump-4.6 -p quota.db
VERSION=3
format=print
type=btree
db_pagesize=4096
HEADER=END
  priv/quota/messages
  0
  priv/quota/storage
  0
DATA=END

- mysql: the dict-server connects, but nothing is written to the table
dovecot: Jul 02 11:24:13 Info: dict: mysql: Connected to mail
the mysql log shows no entries for an update or insert to the table  
"quota"

- pgsql: same: the dict-server connects, but nothing is written to the  
table
dovecot: Jul 02 10:56:45 Info: dict: pgsql: Connected to mail
the pgsql log shows no activities

System:
FreeBSD 6.2-STABLE-200709

dict-quota.conf:
connect = host= ...
table = quota
select_field = current
where_field = path
username_field = username
