Note: This tutorial is appliable to 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-user" (Debian/Ubuntu) or "/usr/local/etc/amavisd.conf" (FreeBSD), find below settings and change them:

# 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 by default in iRedMail-0.7.0):

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

• 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_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". Use drop-down menu list to release or delete them.

Screenshots:

• View quarantined mails
• Expand quarantined mail to view mail headers and body
