## General (All backends should apply these upgrade 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

    0.8.0

### 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.

### Set strict file permission for Dovecot config files

There's one world-readable Dovecot config file, we should set strict file owner and permission on it so that it won't leak SQL server infomation.

Please execute below command to fix it, then restart Dovecot service:

NOTE: The file name on different Linux/BSD distributions may be different, it should be `dovecot-used-quota.conf` or `used-quota.conf`.

- On RHEL/CentOS/Scientific Linux 5.x:

    # chown dovecot:dovecot /etc/dovecot-used-quota.conf
    # chmod 0500 /etc/dovecot-used-quota.conf

- On RHEL/CentOS/Scientific Linux 6.x, Debian, Ubuntu, openSUSE:

    # chown dovecot:dovecot /etc/dovecot/used-quota.conf
    # chmod 0500 /etc/dovecot/used-quota.conf

- On FreeBSD:

    # chown dovecot:dovecot /usr/local/etc/dovecot-used-quota.conf
    # chmod 0500 /usr/local/etc/dovecot-used-quota.conf

### Enable greylist opt in and opt out in Policyd

Note: If you're running Ubuntu 11.10 or later releases, there's no Policyd (v1.8) installed at all, it's replaced by Cluebringer, a.k.a. Policyd v2. So it's safe to skip this step.

Some people are fairly irate when it comes to mail and refuse wanting to have any type of delay. this feature enables each and every person the ability to not subject themselves to greylisting. this feature is also VERY usefull when you dont want to subject EVERY person to greylisting at once but instead allows you to enable it in batches/groups of users so you get a feel on the type of complaints or praise from your users.

Please update Policyd setting `OPTINOUT` and `OPTINOUTALL=1` to 1 to enable greylist opt-in/opt-out:

    * On RHEL/CentOS/Scientific Linux, it's set in file `/etc/policyd.conf`.
    * On Debian/Ubuntu, it's set in file `/etc/postfix-policyd.conf`.
    * On openSUSE, it's set in file `/etc/policyd.conf`.
    * On FreeBSD, it's set in file `/usr/local/etc/postfix-policyd-sf.conf`.

    # Part of file: policyd.conf

    OPTINOUT=1
    OPTINOUTALL=1

Restarting Policyd service is required to make it work.

Notes:

- iRedAdmin-Pro customers can manage greylist opt-in with one lick with the latest iRedAdmin-Pro releases, in domain profile page or user profile page, under tab `Advanced`.
- For more details about how to set greylist opt-in manually with MySQL command line or phpMyAdmin, please refer to Policyd official document: http://policyd.sourceforge.net/readme.html (Section "Greylist Opt-in / Opt-out")

### Enable case insensitive user authentication in Roundcube webmail

Please change below setting to `true` in Roundcube webmail config file 'config/main.inc.php' to enable case insensitive user authentication. The config file should be:

    * `/var/www/roundcubemail/config/main.inc.php` on RHEL/CentOS/Scientific Linux
    * `/usr/share/apache2/roundcubemail/config/config.inc.php` on Debian/Ubuntu
    * `/srv/www/roundcubemail/config/main.inc.php` on openSUSE
    * `/usr/local/www/roundcubemail/config/main.inc.php` on FreeBSD

    # Part of file: config/main.inc.php

    $rcmail_config['login_lc'] = false;

### Fix logrotate setting of Dovecot log files

Open `/etc/logrotate.d/dovecot` and `/etc/logrotate.d/sieve`, update postrotate commands:

- If you're running Dovecot-1.x, please update postrotate command with below value:

    # Part of file: /etc/logrotate.d/dovecot and /etc/logrotate.d/sieve

    postrotate
        /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true
    endscript

- If you're running Dovecot-2.x, please update postrotate command with below value:

    # Part of file: /etc/logrotate.d/dovecot, /etc/logrotate.d/sieve

    postrotate
        doveadm log reopen
    endscript

### [OPTIONAL] Enforce connections over HTTPS in Roundcube webmail

This step is optional but highly recommended for better security.

Please update below parameter in Roundcube config file `roundcubemail/config/main.inc.php` to enforce connections over https for better security. With this option enabled, all non-secure connections will be redirected to `https://`.

    * On RHEL/CentOS/Scientific Linux, Gentoo, OpenBSD, it's `/var/www/roundcubemail/config/main.inc.php`.
    * On Debian/Ubuntu, it's `/usr/share/apache2/roundcubemail/config/main.inc.php`.
    * On openSUSE, it's `/srv/www/roundcubemail/config/main.inc.php`.
    * On FreeBSD, it's `/usr/local/www/roundcubemail/config/main.inc.php`.

    # Part of file: roundcubemail/config/main.inc.php

    $rcmail_config['force_https'] = true;

Restarting Apache web server is required.

### [OPTIONAL] Enforce connections over POP3S/IMAPS in Dovecot

This step is OPTIONAL but highly recommended for better security. Since it may requires update on your mail users' MUA (e.g. Thunderbird, Outlook), please notify your mail users before this change.

Since iRedMail-0.8.0, all clients are forced to use IMAPS and POPS (via STARTTLS) for better security by default. To enable this feature, please update below parameters in your Dovecot config file, `dovecot.conf`.

    * On RHEL/CentOS/Scientific Linux 5.x, it's `/etc/dovecot.conf`.
    * On RHEL/CentOS/Scientific Linux 6.x, it's `/etc/dovecot/dovecot.conf`.
    * On Debian/Ubuntu, it's `/etc/dovecot/dovecot.conf`.
    * On openSUSE, it's `/etc/dovecot/dovecot.conf`.
    * On FreeBSD, it's `/usr/local/etc/dovecot/dovecot.conf`.

    # Part of file: dovecot.conf

    ssl = required
    disable_plaintext_auth = yes

Restarting Dovecot service is required.

## OpenLDAP backend special

### Add internal service required by Doveadm

NOTE: This step is applicable to both Dovecot-1.x and Dovecot-2.x.

To use `doveadm` command provided by Dovecot-2, please add one more value of attribute 'enabledService' for mail user.

- Download python script used to adding missing values.

    # cd /root/
    # wget https://github.com/iredmail/iRedMail/raw/1.0/update/ldap/updateLDAPValues_074_to_080.py

- Open `updateLDAPValues_074_to_080.py`, config LDAP server related settings in file head. e.g.

    # Part of file: updateLDAPValues_074_to_080.py

    uri = 'ldap://127.0.0.1:389'
    basedn = 'o=domains,dc=example,dc=com'
    bind_dn = 'cn=vmailadmin,dc=example,dc=com'
    bind_pw = 'passwd'

You can find required LDAP credential in iRedAdmin config file or `iRedMail.tips` file under your iRedMail installation directory. Using either `cn=Manager,dc=xx,dc=xx` or `cn=vmailadmin,dc=xx,dc=xx` as bind dn is ok.

- Execute this script, it will add missing values for mail accounts:

    # python updateLDAPValues_074_to_080.py

It will print progress message in the terminal, just be patient.

If you're running Dovecot-2, please add below lines in `dovecot-ldap.conf` to make command `doveadm mailbox` work as expected:

    # Part of file: dovecot-ldap.conf

    iterate_attrs   = mail=user
    iterate_filter  = (&(objectClass=mailUser)(accountStatus=active)(enabledService=mail))

## MySQL backend special

### Add internal service required by Doveadm

To use doveadm command provided by Dovecot-2, please add one more column in MySQL table `vmail.mailbox` with below command:

    # mysql -uroot -p
    mysql> USE vmail;
    mysql> ALTER TABLE mailbox ADD COLUMN enabledoveadm TINYINT(1) NOT NULL DEFAULT 1;
