ChangeLog

• Jun 29, 2020: initial release.

General (All backends should apply these changes)

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:

1.3

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

Please follow below tutorial to upgrade iRedAPD to the latest stable release: Upgrade iRedAPD to the latest stable release

Upgrade mlmmjadmin to the latest stable release

Please follow below tutorial to upgrade mlmmjadmin to the latest stable release: Upgrade mlmmjadmin to the latest stable release

Upgrade Roundcube webmail to the latest stable release (1.4.6)

Roundcube 1.4.6 fixes few security issues, all users are encouraged to upgrade as soon as possible.

• How to upgrade Roundcube.

References:

• 07 June 2020, Updates 1.4.6 and 1.3.13 released
• 02 June 2020, Security updates 1.4.5 and 1.3.12 released

Fixed: can not manage mail filters with Roundcube on CentOS 7

On CentOS 7, the Roundcube official plugin managesieve doesn't work with TLSv1.1 and TLSv1.2, so we have to re-enable TLSv1 in Dovecot, otherwise you can not manage mail filters with Roundcube.

Open file /etc/dovecot/dovecot.conf, find the ssl_protocols parameter like below:

ssl_protocols = !SSLv2 !SSLv3 !TLSv1 !TLSv1.1

Remove !TLSv1 and restart Dovecot service:

ssl_protocols = !SSLv2 !SSLv3 !TLSv1.1

Note: TLSv1 and TLSv1.2 are supported with this change.

Fixed: inconsistent Fail2ban jail names

iRedMail-1.2 and 1.2.1 introduced SQL integration in Fail2ban, but there're few inconsistent jail names which caused unbanning IP from iRedAdmin-Pro doesn't work. Please run commands below to fix them.

cd /etc/fail2ban/jail.d/
perl -pi -e 's#dovecot-iredmail#dovecot#g' dovecot.local

perl -pi -e 's#postfix-pregreet-iredmail#postfix-pregreet#g' postfix-pregreet.local
perl -pi -e 's#name=postfix,#name=postfix-pregreet,#g' postfix-pregreet.local

perl -pi -e 's#postfix-iredmail#postfix#g' postfix.local
perl -pi -e 's#roundcube-iredmail#roundcube#g' roundcube.local
perl -pi -e 's#sogo-iredmail#sogo#g' sogo.local

OpenLDAP backend special

Add missing index for SQL column msgs.time_iso in amavisd database

Please run SQL commands below as MySQL root user:

USE amavisd;
CREATE INDEX msgs_idx_time_iso ON msgs (time_iso);

Improvement: Store more info in Fail2ban SQL db

With changes below, we now store more info in Fail2ban SQL database:

• Matched log lines which triggerred the ban
• Number of times the failure occurred until ban
• Reverse DNS name of banned IP address

Please run SQL commands below as MySQL root user:

USE fail2ban;
ALTER TABLE banned ADD COLUMN failures INT(2) NOT NULL DEFAULT 0;
ALTER TABLE banned ADD COLUMN loglines TEXT;
ALTER TABLE banned ADD COLUMN `rdns` VARCHAR(255) NOT NULL DEFAULT '';
CREATE INDEX rdns ON banned (`rdns`);

Now open file /etc/fail2ban/action.d/banned_db.conf, find the actionban = line like below:

actionban   = /usr/local/bin/fail2ban_banned_db ban <ip> <port> <protocol> <name>

Replace it by:

actionban   = /usr/local/bin/fail2ban_banned_db ban <ip> <port> <protocol> <name> <ipjailfailures> <ipjailmatches>

Download improved shell script and replace the existing one:

cd /usr/local/bin
wget -O fail2ban_banned_db https://github.com/iredmail/iRedMail/raw/1.3/samples/fail2ban/bin/fail2ban_banned_db
chmod 0550 fail2ban_banned_db

Now restart Fail2ban service.
