Configure quarantine digest settings

You can specify settings for the quarantine digest, an email sent to users that lists their quarantined emails. You can release emails from quarantine digest directly from the user portal.


Quarantine digest lists all emails that are identified as spam and quarantined by the Sophos Firewall anti-spam engine. Sophos Firewall emails the quarantine digest to all users as per the configured frequency (hourly, daily, or weekly). From the digest, users can sort through the quarantined emails.

The quarantine digest contains the date and time of email receipt, sender and recipient email addresses, and the email subject.


The quarantine digest is available only in Sophos Firewall XG 105, Cyberoam CR25iNG, Sophos UTM SG105, and higher models.
