## General (All backends should apply these steps)

### Update `/etc/iredmail-release` with new 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:

```
0.9.7
```

### Upgrade iRedAPD (Postfix policy server) to the latest stable release (2.2)

Please follow below tutorial to upgrade iRedAPD to the latest stable release:
[Upgrade iRedAPD to the latest stable release](./upgrade.iredapd.html)

### Fixed: SOGo backup script contains 3 issues

SOGo backup script `/var/vmail/backup/backup_sogo.sh` shipped in iRedMail-0.9.7
and earlier releases contains 3 issues:

- it cannot remove old backup files
- it doesn't set correct owner and permission on backup files
- it cannot find command `sogo-tool` on FreeBSD. This issue causes our script
  didn't backup any sogo data at all.

To fix them, please download the latest version and override the one on your
system:

!!! attention

    Script `backup_sogo.sh` uses `/var/vmail/backup` to store backup files by
    default, if you use a different directory, please edit this file and modify
    parameter `BACKUP_ROOTDIR=` to use the correct one.

```
cd /var/vmail/backup/
wget https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/tools/backup_sogo.sh
chown root backup_sogo.sh
chmod 0400 backup_sogo.sh
```

### [OPTIONAL] Fix improper expected DNSBL filter for site `b.barracudacentral.org`

Postfix config file generated by iRedMail enables DNSBL service for postscreen
service like below:

```
postscreen_dnsbl_sites =
    zen.spamhaus.org=127.0.0.[2..11]*3
    b.barracudacentral.org=127.0.0.[2..11]*2
```

but site `b.barracudacentral.org` returns only domain `127.0.0.2` (instead of
a range from `127.0.0.2` to `127.0.0.11`), so we should change the
`b.barracudacentral.org=127.0.0.[2..11]*2` line to:

```
postscreen_dnsbl_sites =
    zen.spamhaus.org=127.0.0.[2..11]*3
    b.barracudacentral.org=127.0.0.2*2
```

Reloading or restarting Postfix is required.

### [OPTIONAL] Log mail subject, sender, size in mail deliver log

If you may need to get more info of (locally) delivered mail messages,
Dovecot setting `deliver_log_format` can log extra mail subject, sender, and
message size in mail deliver log. Please append this setting in Dovecot config
file `dovecot.conf`, then restart or reload Dovecot service.
* On Linux/OpenBSD, it's `/etc/dovecot/dovecot.conf`
* On FreeBSD, it's `/usr/local/etc/dovecot/dovecot.conf`

```
deliver_log_format = from=%{from}, envelope_sender=%{from_envelope}, subject=%{subject}, msgid=%m, size=%{size}, %$
```

## MySQL/MariaDB backends

### Fixed: User under disabled domain is able to send email with smtp protocol

Dovecot is IMAP/POP3/Managesieve server, also a SASL auth server for Postfix.
If mail domain is disabled, users under this domain are not able to use
IMAP/POP3/Managesieve services, but there's a bug in Dovecot SQL query, it
doesn't check domain status while performing smtp sasl auth.
Please follow steps below to fix it.

* Open file `/etc/dovecot/dovecot-mysql.conf` (Linux/OpenBSD) or
  `/usr/local/etc/dovecot/dovecot-mysql.conf` (FreeBSD), find the
  `password_query` line like below:

```
password_query = SELECT password, allow_nets FROM mailbox WHERE username='%u' AND enable%Ls%Lc=1 AND active=1
```

* Replace it by lines below:

```
password_query = SELECT mailbox.password, mailbox.allow_nets \
        FROM mailbox,domain \
       WHERE mailbox.username='%u' \
             AND mailbox.`enable%Ls%Lc`=1 \
             AND mailbox.active=1 \
             AND mailbox.domain=domain.domain \
             AND domain.backupmx=0 \
             AND domain.active=1
```

* Save your change and restart Dovecot service.

## PostgreSQL backend

### Fixed: User under disabled domain is able to send email with smtp protocol

Dovecot is IMAP/POP3/Managesieve server, also a SASL auth server for Postfix.
If mail domain is disabled, users under this domain are not able to use
IMAP/POP3/Managesieve services, but there's a bug in Dovecot SQL query, it
doesn't check domain status while performing smtp sasl auth.
Please follow steps below to fix it.

* Open file `/etc/dovecot/dovecot-pgsql.conf` (Linux/OpenBSD) or
  `/usr/local/etc/dovecot/dovecot-pgsql.conf` (FreeBSD), find the
  `password_query` line like below:

```
password_query = SELECT password, allow_nets FROM mailbox WHERE username='%u' AND enable%Ls%Lc=1 AND active=1
```

* Replace it by lines below:

```
password_query = SELECT mailbox.password, mailbox.allow_nets \
        FROM mailbox,domain \
       WHERE mailbox.username='%u' \
             AND mailbox."enable%Ls%Lc"=1 \
             AND mailbox.active=1 \
             AND mailbox.domain=domain.domain \
             AND domain.backupmx=0 \
             AND domain.active=1
```

* Save your change and restart Dovecot service.
