Product Updates - Beta Environment

This section details updates to the Secure Email Threat Defense Beta Environment for our Beta testing customers.

December 11 2025

Bulk remediation and reclassification is now possible from the UI. Previously, you could remediate or reclassify only 100 messages at a time. Bulk remediation allows you to remediate or reclassify all messages in a search result, up to a 50,000 message limit. For details, see Bulk Move and Reclassify Messages.

You can now pivot from the High Impact Personnel list to a filtered list of the messages that were flagged as impersonations.

SMTP/Inline Mode: Outbound scanning is now enabled to ensure malicious data is identified and addressed before exiting the network.

Authentication error reporting (SPF/DKIM/DMARC)
- Added SPF/DKIM/DMARC errors to message report timelines.
- Added visibility to the status and reason for SPF/DKIM/DMARC errors to the hover help on the Sender Information widget on the message report.
- Added x-headers for authentication failure so MS Admins can configure Transport Rules on Microsoft to set custom delivery routes.
- Added email sender authentication status and error codes to message search and message event log export APIs.
You can now configure Secure Email Threat Defense as a first hop in your inline mode mail path. You can configure relay hosts for imported domains.
Updated connection handling terminology from domain to hostname/FQDN for improved clarity.
Fixed issues with exporting Blocked Connection Logs to meet Excel formatting and better file naming.

Policy Exceptions by Recipient. You can create rules by going to Configuration > Policy configuration.
Notifications of user role changes made by administrators. To turn these notifications on, go to Administration > Business.
