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

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.
