Hide Block-Listed Emails from End Users

Harmony Email & Collaboration now gives administrators control over the visibility of block-listed emails in end-user portals and quarantine digest emails.

Context and Purpose

While the vast majority of attacks are prevented by Harmony Email & Collaboration’s advanced AI engines, some of the emails end up in the quarantine due to block-list rules added by administrators. While these emails are automatically quarantined and prevented from reaching users’ mailboxes, they can still appear in the end-user portal and daily quarantine digest. For many organizations, this visibility poses unnecessary risks and increases operational overhead—especially for SOC teams managing user inquiries and support tickets related to these messages.

New Capability and Benefits

To address this, Harmony Email & Collaboration now introduces a new control that allows administrators to completely hide block-listed emails from both the end-user portal and daily quarantine digest.

This gives security teams more flexibility to:

• Minimize user exposure to messages already classified as high-risk or irrelevant.
• Reduce user confusion and support requests.
• Align email visibility policies with organizational risk tolerance.

 How to Configure

Go to Security Settings > User Interaction > Quarantine > End User Permissions > Block Listed Emails
and check or uncheck Include block-listed items in digest and portal.
