Hi,

sorry but I'm new to dovecot and this list and don't know how to proceed with my dovecot installation. I was trying to set up an Mailserver with Postfix, Dovecot and PostgreSQL. Everything was working fine till I wanted to integrate quota support. When I activate it by adding quota to the the imap plugin section (like described in the wiki) I get the following error every time I try to login:

Jan 20 19:32:07 kauket dovecot: IMAP(user@dmain.de): Unknown quota backend: quota=maildir Jan 20 19:32:07 kauket dovecot: child 11288 (imap) returned error 89 Jan 20 19:32:07 kauket dovecot: imap-login: Login:user=user@domain.de, method=plain, rip=::ffff:1.2.3.4, lip=::ffff:1.2.3.5, TLS

I tried to set quota = maildir:storage=10240 in the plugin section, too and got the same error.

I already talked to some dovecot users bot nobody could help me and I hope you can give me an advice what could be the mistake.

Here is my Config:

# /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: [::] ssl_cert_file: /etc/ssl/certs/kauket.maedness.de.crt ssl_key_file: /etc/ssl/certs/kauket.maedness.de.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: dovecot-auth mail_extra_groups: mail mail_location: maildir:/var/mail/%h mail_plugins: quota imap_quota auth default: user: dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf

# grep -ve '^[ ]*#' -e '^$' dovecot-sql.conf driver = pgsql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 10000 AS uid, 8 AS gid, quota=maildir:storage=' || quota AS quota, maildir AS home FROM mailbox WHERE username = '%u'

The system is a debian stable (etch) with package version 1.0.rc15-2etch1 and dovecot --version tells 1.0.rc15.

I know the this version of dovecot is a little bit ancient but I hope you can still help me. I even don't know if it's only a bug in the package or if it's a bug in dovecot itself.

I thank you for all clues and advices.

Sincerly yours,

Sascha
