Fix incorrect per-user sieve_dir setting in Dovecot
Note: This fix is applicable to Dovecot-1.x, you can check Dovecot version
with command dovecot -n
.
In /etc/dovecot.conf
or /etc/dovecot/dovecot.conf
, remove the last slash
(/
) in setting sieve_dir =
like below:
# Part of file: dovecot.conf
# Original setting:
#sieve_dir = /var/vmail/sieve/%Ld/%Ln/
# Change to:
sieve_dir = /var/vmail/sieve/%Ld/%Ln # <-- Remove the last slash.
Add indexes for Amavisd database
$ mysql -uroot -p
mysql> USE amavisd;
mysql> ALTER TABLE maddr ADD INDEX maddr_idx_email (email);
mysql> ALTER TABLE maddr ADD INDEX maddr_idx_domain (domain);
mysql> ALTER TABLE msgs ADD INDEX msgs_idx_content (content);
mysql> ALTER TABLE msgs ADD INDEX msgs_idx_content_time_num (content, time_num);
mysql> ALTER TABLE msgs ADD INDEX msgs_idx_mail_id (mail_id);
mysql> ALTER TABLE quarantine ADD INDEX quar_idx_mail_id (mail_id);
[Debian and Ubuntu special] Assign Apache daemon user to group adm
Note: This fix is applicable to only Debian and Ubuntu.
Assign Apache daemon user to group adm
to avoid Awstats cron job issue.
# usermod -g adm www-data
OpenLDAP backend special
Fix incorrect calculation of mailbox quota
There's a bug in iRedMail-0.7.3 and all earlier versions: Mailbox quota gets calculated per user and per user alias account, so both email addresses get their own mailbox quota usage. Here's the solution to fix it.
- Open
/etc/dovecot-ldap.conf
(on RHEL/CentOS/Scientific Linux) or/etc/dovecot/dovecot-ldap.conf
(on Debian/Ubuntu/openSUSE) or/usr/local/etc/dovecot-ldap.conf
(on FreeBSD), prependmail=user,
in bothuser_attrs =
andpass_attrs =
like below:
# Part of file: dovecot-ldap.conf
# Original settings:
#pass_attrs = userPassword=password
#user_attrs = homeDirectory=home,[...OMIT OTHER SETTINGS HERE...]
# Changed:
pass_attrs = mail=user,userPassword=password
user_attrs = mail=user,homeDirectory=home,[...OMIT OTHER SETTINGS HERE...]
Restarting Dovecot service is required.
MySQL backend special
Store realtime mailbox quota usage in seperate SQL table
In iRedMail-0.7.3 and some earlier versions, Dovecot stores realtime mailbox
quota usage in MySQL database in two columns: mailbox.bytes
,
mailbox.messages
, if they have invalid values (e.g. empty value, non-integer
value), Dovecot will update them with two SQL commands:
- delete record with SQL:
DELETE FROM mailbox WHERE username='xxx@yyy.com'
- create a new record with current, correct quota info. SQL:
INSERT INTO mailbox (username, bytes, messages) VALUES ('xxx@yyy.com', xx, xx)
As you can see, first sql command will delete iRedMail mail user, that's critial issue. So we have to store realtime mailbox quota usage in a separate MySQL table to avoid similar issues.
Below are steps to store realtime mailbox quota usage in a separate SQL table:
- Create new SQL table
vmail.used_quota
to store real-time mailbox quota and drop unused SQL columns:mailbox.bytes
,mailbox.messages
:
# mysql -uroot -p
mysql> USE vmail;
mysql> CREATE TABLE IF NOT EXISTS `used_quota` (
`username` VARCHAR(255) NOT NULL,
`bytes` BIGINT NOT NULL DEFAULT 0,
`messages` BIGINT NOT NULL DEFAULT 0,
PRIMARY KEY (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
mysql> ALTER TABLE mailbox DROP COLUMN bytes;
mysql> ALTER TABLE mailbox DROP COLUMN messages;
-
Replace
table = mailbox
withtable = used_quota
in below config file, so that Dovecot will store mailbox quota in new SQL table.- On RHEL/CentOS/Scientific Linux 5.x, please update
/etc/dovecot-used-quota.conf
, on 6.x, please update/etc/dovecot/used-quota.conf
. - On Debian/Ubuntu, please update
/etc/dovecot/dovecot-used-quota.conf
. - On openSUSE, please update
/etc/dovecot/dovecot-used-quota.conf
. - On FreeBSD, please update
/usr/local/etc/dovecot-used-quota.conf
.
- On RHEL/CentOS/Scientific Linux 5.x, please update

Restarting Dovecot service is required.
