## General (All backends must apply these steps)

### Update /etc/iredmail-release with iRedMail version number

iRedMail stores the release version in `/etc/iredmail-release` after
installation, it's recommended to update this file after you upgraded iRedMail,
so that you can know which version of iRedMail you're running. For example:

```
# File: /etc/iredmail-release

0.8.6
```

### Upgrade Roundcube webmail to the latest stable release

Please follow Roundcube official tutorial to upgrade Roundcube webmail to the
latest stable release immediately: [How to upgrade Roundcube](https://github.com/roundcube/roundcubemail/wiki/Upgrade).

release: http://docs.phpmyadmin.net/en/latest/setup.html#upgrading-from-an-older-version

### Enable Opportunistic TLS support in Postfix when sending mail to remote SMTP server

This feature is used to secure your mail transaction when sending email from
your iRedMail server (Postfix) to remote SMTP server. Refer to Postfix document
for more technical details: [smtp_tls_security_level](http://www.postfix.org/postconf.5.html#smtp_tls_security_level)

* Add required parameters in Postfix:

```
# postconf -e smtp_tls_security_level='may'
# postconf -e smtp_tls_CAfile='$smtpd_tls_CAfile'
```

* Then restart Postfix service:

```
# ---- On Linux ----
# /etc/init.d/postfix restart

# ---- On FreeBSD ----
# /usr/local/etc/rc.d/postfix restart

# ---- On OpenBSD ----
# /etc/rc.d/postfix restart
```

### Alter Cluebringer database

__IMPORTANT NOTE__: This step is required if you're running Cluebringer. And
please skip this step if you're running Policyd-1.8.

For better management, we have to do some modification on Cluebringer database,
for example, add new columns, add new indexes. We have a SQL file you can use
to finish this in one step.

Please download below two SQL files shipped in iRedMail-0.8.6, and save it as
file /root/extra.sql, and /root/column_character_set.mysql:

* https://bitbucket.org/zhb/iredmail/raw/4d7b14fc40bb2467fb4efcc4ce08ac9fc037224c/iRedMail/samples/cluebringer/extra.sql
* https://bitbucket.org/zhb/iredmail/raw/4d7b14fc40bb2467fb4efcc4ce08ac9fc037224c/iRedMail/samples/cluebringer/column_character_set.mysql

For MySQL, please login to MySQL server as `root` user and import this sql file:

```
# mysql -uroot -p
mysql> USE cluebringer;
mysql> SOURCE /root/extra.sql;
mysql> SOURCE /root/column_character_set.mysql;
```

For PostgreSQL, please login to PostgreSQL admin user `postgres` and import
this sql file:

```
# su - postgres
$ psql -d cluebringer
sql> \i /root/extra.sql;
```

That's all.

### Add cron job to cleanup Cluebringer database

__IMPORTANT NOTE__: This step is required if you're running Cluebringer. And
please skip this step if you're running Policyd-1.8.

We have to delete old/expired entries from database to keep SQL query fast.

NOTE: On RHEL/CentOS and openSUSE, you must update cluebringer package to
version '2.0.13-3' with yum first:

```
# yum update cluebringer
```

* Add cron job with command `crontab`:

```
# crontab -e -u root
```

Now add cron job:

*  On RHEL/CentOS, openSUSE
```
1   3   *   *   *   /usr/sbin/cbpadmin --config=/etc/policyd/cluebringer.conf --cleanup > /dev/null
```

* On Debian/Ubuntu:
```
1   3   *   *   *   /usr/sbin/cbpadmin --config=/etc/cluebringer/cluebringer.conf --cleanup > /dev/null
```

* On FreeBSD:
```
1   3   *   *   *   /usr/local/bin/cbpadmin --config=/usr/local/etc/cluebringer.conf --cleanup > /dev/null
```

* On OpenBSD: not required since OpenBSD doesn't have cluebringer package installed.
