Download Symantec Messaging Gateway 10.7.5

Symantec Messaging Gateway is a product for securing incoming and outgoing mail flows. It builds on Brightmail, which was acquired by Symantec in 2004, which in turn was acquired by Broadcom in 2019. Although both acquisitions happened some time ago, they are still reflected in the name and description of the product. The program offers anti-spam and anti-malware options, advanced content filtering and data loss prevention, and also offers encryption options by integrating with Symantec encryption products. SMG can be run on a companion hardware appliance or virtually in VMware, Hyper-V, or KVM. Version 10.7.5 has been released with the following changes:

What’s new in SMG 10.7.5

This release (10.7.5) introduces support for the deployment of Symantec Messaging Gateway on Linux KVM platforms.

This release also introduces WebPulse integration for URL category filtering. Administrators can now create content filtering policies to detect and manage spam and other unwanted content based on the URLs contained in mail headers and body content, leveraging Broadcom’s best-of-breed URL categorization service.

IMPORTANT: Communication with the WebPulse service requires that the Symantec Messaging Gateway can reach several domains on ports 80 (HTTP) and 443 (HTTPS). Ensure that your network security infrastructure permits access from your SMG appliance(s) to the following URLs for HTTP and HTTPS traffic:

• sp.cwfservice.net
• list.bluecoat.com
• webpulse.es.bluecoat.com
• subscription.es.bluecoat.com

If your organization uses SMG in a closed network environment, remove the check next to Enable Relationship-based AI for File specific detections on the Malware > Email Scan Settings page. Failure to do this will result in delays and instability in your environment, as the appliance attempts to look up URLs as they’re detected.

Release 10.7.5 also includes changes to the Modify Clickable URLs action in Content Filtering policies. These changes allow users to modify only the URLs that match certain criteria, such as Spam URLs, Malicious URLs, or Unknown URLs.

This release also includes:

• The ability to undo URL modification for outbound messages using Content Filtering.
• A change in inbound mail processing that causes SMG to reject messages if the sender presents a client certificate that cannot be validated.
• A fix for network access issues for the S450 hardware platform.
• Support for a large number of new file types for email content filtering policies.
• Support for VMware 7.0.
