Download Symantec Messaging Gateway 10.6.2

Symantec Messaging Gateway is a product for securing incoming and outgoing mail flows. It builds on Brightmail, which was acquired by Symantec in 2004. Although that happened more than twelve years ago, the old name is still mentioned in the product with the addition ‘powered by Brightmail’. The program offers anti-spam and anti-mailware 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 or Hyper-V. Version 10.6.2 has recently been released with the following changes:

What’s new in SMG 10.6.2

Symantec recommends that all customers using version 10.6 of the SMG software update at their earliest convenience.

New features include the following:

• The ability to disable clickable URLs in messages.
• Previously, the MTA would immediately retry the first message in the queue for each domain when it was restarted. In this version, the MTA waits for the completion of the retry interval before it attempts delivery again.

This release also fixes known defects and addresses known vulnerabilities.

Resolved issues:

• The sensor for the CPU temperature status erroneously returned “Not Available” for some 8340s.
• Disabling SSLv3 in all SMTP conversations did not prevent RC4 ciphers from being used.
• On some 8340s a fan status error appeared.
• Control Center was unable to send updated configuration files to scanners if the configuration file is over 7MB.
• SSH weak MAC algorithms were enabled in SMG.
• A message had both “strip all attachments” and “strip and delay in suspect virus quarantine” actions. When the message was released from quarantine, all attachments were present.

• Sending Brightmail admin events to remote syslog were not enabled when a Control Center-only appliance was used.
• Control Center did not process new statistics due to a missing stats file.
• DNS latency detection/protection resulted in large numbers of ERROR level messages in the Brightmail Engine logs.
• In some cases, a Dictionary rule does not catch a non-US ASCII word in the subject.

• Attempts to modify DDS sources failed with an invalid credentials error and/or information was not saved.
• Network connection errors appear in conduit_log during installation.
• Recipient Validation incorrectly rejected Recipients with a BATV tag.
