Note: This tutorial is appliable for iRedMail-0.7.0 and later versions. If you're using iRedMail-0.6.1 and earlier versions, please refer to this tutorial.

Summary

iRedMail-0.7.0 has quarantining related settings pre-configured, but users can't manage quarantined mails, so quarantining is disabled by default.

Since iRedAdmin-Pro supports releasing and deleting quarantined mails, you can easily enable quarantining with this tutorial.

Configure Amavisd to enable quarantining

• Edit Amavisd config file "/etc/amavisd.conf" (RHEL/CentOS/openSUSE) or "/etc/amavis/conf.d/50-users" (Debian/Ubuntu) or "/usr/local/etc/amavisd.conf" (FreeBSD), find below settings and change them:

$final_spam_destiny       = D_DISCARD;                 # <- Change it to D_DISCARD
$spam_quarantine_to = 'spam-quarantine';           # <- Remove '#' at the beginning of line.
$spam_quarantine_method = 'sql:';           # <- Remove '#' at the beginning of line.

Also, make sure you have below lines configured in same config file (It's configured by default in iRedMail-0.7.0):

$sql_allow_8bit_address = 1;
$timestamp_fmt_mysql = 1;
@storage_sql_dsn = (
    ['DBI:mysql:database=...],
);

• Restart amavisd service to make it work.

Configure iRedAdmin-Pro to manage quarantined mails

• Edit iRedAdmin-Pro config file "/var/www/iredadmin/settings.ini" (RHEL/CentOS) or "/usr/share/apache2/iredadmin/settings.ini" (Debian/Ubuntu) or "/srv/www/iredadmin/settings.ini" (openSUSE) or "/usr/local/www/iredadmin/settings.ini" (FreeBSD), make sure you have correct settings in "[amavisd]" section like below:

[amavisd]
quarantine = True               # <- Set to True to enable quaranting management.
server = 127.0.0.1
quarantine_port = 9998

logging_into_sql = True          # <- Set to True to view log of sent/received mails.

host = 127.0.0.1
port = 3306
db = amavisd 
user = amavisd
passwd = [passwd_of_mysql_user_amavisd]

• Restart Apache web server to make it work.
• You can now login to iRedAdmin-Pro, and view quarantined mails via menu "System -> Quarantined Mails". Use drop-down menu list to release or delete them.
