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

Summary

Since iRedMail-0.7.0, quarantining related settings are configured but disabled by default, you can easily enable quarantining with this tutorial.

With below steps, Virus/Spam/Banned emails will be quarantined into SQL database. You can manage quarantined emails with iRedAdmin-Pro.

Configure Amavisd to enable quarantining

• Edit Amavisd config file, find below settings and update them. If it doesn't exist, just add them.
  • on RHEL/CentOS/openSUSE, it's /etc/amavisd.conf or /etc/amavisd/amavisd.conf.
  • on Debian/Ubuntu/Mint, it's /etc/amavis/conf.d/50-user
  • on FreeBSD, it's /usr/local/etc/amavisd.conf
  • on OpenBSD, it's /etc/amavisd.conf

# Change below two settings to D_DISCARD.
$final_spam_destiny = D_DISCARD;
$final_banned_destiny = D_DISCARD;

#
# Quarantine SPAM into SQL server.
#
$spam_quarantine_to = 'spam-quarantine';    # <- Remove '#' at the beginning of line.
$spam_quarantine_method = 'sql:';           # <- Remove '#' at the beginning of line.

#
# Quarantine VIRUS into SQL server.
#
$virus_quarantine_to = 'virus-quarantine';   # <- Remove '#' at the beginning of line.
$virus_quarantine_method = 'sql:';           # <- Remove '#' at the beginning of line.

#
# Quarantine BANNED emails into SQL server.
#
$banned_quarantine_to = 'banned-quarantine';
$banned_files_quarantine_method = 'sql:';

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

@storage_sql_dsn = (
    ['DBI:...],
);

• Restart amavisd service to make it work.

Configure iRedAdmin-Pro to manage quarantined mails

• Edit iRedAdmin-Pro config file settings.ini, make sure you have correct settings in "[amavisd]" section like below:
  • on Red Hat Enterprise Linux, CentOS, Scientific Linux, it's /var/www/iredadmin/settings.ini
  • on Debian, Ubuntu, Mint, it's /usr/share/apache2/iredadmin/settings.ini
  • on openSUSE, it's /srv/www/iredadmin/settings.ini
  • on Gentoo Linux, it's /var/www/iredadmin/settings.ini
  • on FreeBSD, it's /usr/local/www/iredadmin/settings.ini
  • on OpenBSD, it's /var/www/iredadmin/settings.ini

[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_sql_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". Choose action in drop-down menu list to release or delete them.
