Hello,

I am trying to get per-user quotas working. My thanks to all who have helped so far.

To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine. Here's my current doveconf -n output it is producing the following debug error related to the userdb sql query:

# 2.1.10: /etc/dovecot/dovecot.conf # XXX dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_gid = 5000 first_valid_uid = 5000 hostname = XXX last_valid_gid = 5000 last_valid_uid = 5000 mail_location = maildir:/home/vmail/%d/%n:LAYOUT=fs mail_plugins = " quota" namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::proxy::quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } inet_listener imaps { address = xxx xxxx ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/server.crt ssl_key = </etc/ssl/private/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = " quota imap_quota" }

Refer to server log for more information.

I am wanting a majority of my users to have the global 1GB quota, but the users in the quota table to have given quotas. Here's what the virtual_users and quota tables look like:

mysql> describe virtual_users; +-----------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | domain_id | int(11) | NO | MUL | NULL | | | user | varchar(40) | NO | | NULL | | | password | varchar(128) | NO | | NULL | | +-----------+--------------+------+-----+---------+----------------+ 4 rows in set (0.00 sec)

mysql> describe quota; +----------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------+--------------+------+-----+---------+-------+ | username | varchar(100) | NO | PRI | NULL | | | bytes | bigint(20) | NO | | 0 | | | messages | int(11) | NO | | 0 | | +----------+--------------+------+-----+---------+-------+ 3 rows in set (0.00 sec)

I'd appreciate any help.

Thanks. Dave.
